SEO and UX: The User Experience Factors Google Considers in Rankings

What does SEO and UX alignment mean, and how does Google judge user experience?

SEO and UX alignment means building a page that search engines can understand and that visitors find fast, safe and easy to use. However, Google does not grade this with one score. Instead, it looks at a mix of signals: Core Web Vitals, HTTPS, mobile display, ad density, interstitials and how clearly the main content stands out.

I have worked in digital marketing since 2012. The question I hear most from clients sounds like this: "Our site is fast, so why are we not moving up?" The honest answer rarely changes. User experience alone does not win rankings. However, a poor experience sends away the visitors that good content earned.

In this guide I go through the user experience factors that Google names in its own documentation. I leave practical design trade-offs, such as tabs or menu choices, for another article. Here the focus stays on what Google says it looks at, and on how you can check each item yourself.

What does Google actually mean by "page experience"?

Google's page experience documentation gives site owners a short list of self-assessment questions. That list sets the official frame for the topic. So whenever someone tells you about a new "UX ranking signal", test the claim against these questions first.

• Do your pages have good Core Web Vitals?
• Do you serve your pages securely over HTTPS?
• Does your content display well on mobile devices?
• Does your content avoid an excessive amount of ads that distract from the main content?
• Do your pages avoid intrusive interstitials?
• Can visitors easily tell the main content apart from everything else on the page?

Notice what the list leaves out. Button colours, font taste and animation style do not appear anywhere. In other words, Google cares about how easily a visitor reaches the content, not about your aesthetic preferences. Above all, that distinction matters when you decide where to spend a limited budget.

Is page experience a single ranking signal?

No. In the same document, Google states plainly that there is no single signal. Instead, its core ranking systems look at a variety of signals that align with overall page experience. Google also confirms that its ranking systems use Core Web Vitals.

One sentence in that document is worth pinning above your desk. Google says it always tries to show the most relevant content, even if the page experience is sub-par. As a result, a page with perfect scores that fails to answer the query will not automatically outrank a slower page that nails the answer.

Here is how I summarise it for clients. User experience helps you stand out among pages of similar quality, and it decides whether incoming traffic turns into leads or sales. Still, if you treat it as a cure for thin content, you will end up disappointed. Relevance comes first, then experience. When both are in place, results tend to last.

What are Core Web Vitals and what are the thresholds?

Core Web Vitals are three metrics that Google chose to reflect real user experience: LCP for loading, INP for responsiveness and CLS for visual stability. The official thresholds on web.dev look like this:

One detail often slips past teams. The assessment uses the 75th percentile of page loads, and it treats mobile and desktop separately. Put simply, at least three out of four visits need a good experience. As a result, the numbers on your own fast laptop can mislead you.

Which mistakes hurt LCP, and how do you fix them?

On most business websites, the LCP element is the large hero image or the main heading block on the home page. In my audits, the causes of a slow LCP fall into the same four groups almost every time. First, find out which one applies to your site.

• Uncompressed images that ship desktop dimensions to phones.
• Slow server response, often on cheap shared hosting.
• A hero image that sits behind lazy loading and therefore loads late.
• Heavy CSS and JavaScript files that block rendering.

The fixes, therefore, follow the same order. Converting images to a modern format such as WebP and resizing them to their real display size usually brings the cheapest, fastest win. You can use the image resizer tool for that. Next, remove the lazy loading attribute from the main image above the fold. After that, move on to server and caching work. In short, skip the search for a miracle plugin and clean up images, server and resource order one by one.

Why did INP replace FID, and what does it measure?

INP became an official Core Web Vital in March 2024, taking over from First Input Delay (FID). FID only looked at the delay before the browser started handling the very first interaction. INP, on the other hand, observes clicks, taps and key presses throughout the whole visit. It then reports how long the page takes to show the next visual update.

This change exposed a common problem. Plenty of sites responded quickly to the first click, yet their menus, filters or forms froze later. For example, a category page that stalls for a second after each filter click could look fine under FID. With INP, that sluggishness finally shows up in the data.

Three things usually drag INP down: long JavaScript tasks that block the main thread, too many third party tags and heavy interface components that redraw large parts of the page on every click. Therefore, cleaning out unused tags in your tag manager is often the first improvement you can make without writing code. Then you work with your developer to break up long tasks.

How does layout shift (CLS) drive visitors away?

CLS measures how much content moves around unexpectedly while a page loads. You know the feeling. You start reading, a banner drops in from the top and pushes the text down. Or you aim for "Buy now" and tap an ad instead. In short, few things feel more irritating for users.

Typical sources of layout shift include images and videos without set dimensions, ad slots that load late, web fonts that arrive after the text and notification bars injected above the content. Moreover, these shifts often stay invisible on a developer's fast connection. Instead, they only become obvious on a slow mobile network.

The logic of the fix is simple: reserve space for every element in advance. Give images width and height values. Set a fixed height for ad and embed containers. Keep the fallback font close in size to the web font. In most cases, these steps bring CLS into the good range. As a bonus, complaints about accidental taps usually drop as well.

Why does the difference between field data and lab data matter?

Google's Core Web Vitals assessment relies on real field data from Chrome users. Tools like Lighthouse, by contrast, simulate a single page load in a controlled setting. The two answer different questions. Lab data tells you why a page is slow. Field data tells you what real visitors actually experience.

This gap causes the most common misunderstanding I see. A client celebrates a Lighthouse score of 95, while the Core Web Vitals report in Search Console still lists "poor" URLs. That said, the reverse can happen too. So when you make decisions, treat field data as the truth and use lab tests as a diagnostic tool.

Pages with little traffic may have no field data at all. In that case, Search Console may then group similar pages together or show nothing. I will cover reading a Lighthouse report step by step in a separate article. For now, remember one thing: improve the real user distribution instead of chasing a lab score.

Is HTTPS still a user experience factor?

Yes. HTTPS appears explicitly in Google's page experience questions, and Search Console offers a dedicated HTTPS report. Since most sites already have an SSL certificate today, this item works less like a competitive edge and more like a baseline. Missing it hurts; having it simply keeps you in the game.

In practice, problems rarely come from a missing certificate. Instead, they come from half finished setups. For example, the address bar shows HTTPS, yet some images or scripts still load from HTTP addresses. Another frequent mistake leaves both HTTP and HTTPS versions reachable, with long redirect chains in between.

• Redirect every HTTP address to its HTTPS version with a single 301 step.
• Check the browser console for mixed content warnings.
• Make sure canonical tags and your XML sitemap point to HTTPS URLs.
• Put the certificate renewal date in your calendar, because an expired certificate shows visitors a warning screen.

To spot redirect chains quickly, try the redirect checker.

When do intrusive interstitials become a problem?

In its guidance on interstitials, Google describes intrusive elements as page elements that block the view of the content, usually for promotional purposes. According to the same page, such dialogs frustrate users and make it harder for search engines to understand your content, which may lead to poor search performance.

These are the patterns I flag most often:

• Campaign or newsletter overlays that cover the whole screen as soon as the page opens.
• Consent or sign up steps that send users to a separate page before they see any content.
• Layers with tiny, hidden or delayed close buttons.

Legal requirements, however, sit in a different category. Specifically, the document mentions dialogs such as cookie consent and age verification as exceptions. Even then, Google recommends overlaying the content rather than redirecting the user elsewhere. For promotions, my advice is to use a banner that takes up only a small part of the screen. That way you deliver the message without pulling visitors away from the content.

Why do excessive ads and a clear main content area matter?

The last two questions on Google's list belong together: avoid ads that distract from the main content, and make sure visitors can easily tell the main content apart from everything else. Both come back to one user question: "Where is the information I came for?"

Do not assume this only concerns ad funded publishers. In practice, business websites create the same problem in other ways. For instance, if the first screen of a service page fills up with a slider, a promo strip, a chat bubble and a cookie notice, visitors may leave before they learn what the service is. No ads involved, yet the effect matches.

I use a simple test during audits. I open the page on a phone, take a screenshot of the first screen and try to answer "What does this page offer?" from that image alone. If I cannot answer, the main content does not stand out enough. For that reason, the headline, a short value proposition and the first paragraph should always appear on the first screen. Decorative elements can then move below them.

How do you check mobile usability now that Google retired its tools?

On 1 December 2023, Google retired the Mobile Usability report in Search Console, along with the Mobile-Friendly Test tool and its API. That does not mean mobile experience stopped mattering. Mobile display remains one of the page experience questions, and Google primarily evaluates sites through their mobile versions.

These days I rely on three methods for mobile checks:

1. Lighthouse and Chrome DevTools device mode, to review the layout at different screen widths.
2. The URL Inspection tool in Search Console, to look at the screenshot of the page as Google rendered it.
3. A real mid range Android phone on mobile data, to open the page and complete the form myself.

Please do not skip the third step. The high end phones that designers and managers carry do not reflect what a large share of visitors experience. Small tap targets, tables that overflow the screen and form buttons that vanish behind the keyboard usually show up only in that real device test.

How is helpful content connected to page experience?

Google's guide to helpful, people-first content says that its core ranking systems look to reward content that provides a good page experience. The same guide encourages you to look at the experience as a whole rather than fixating on one or two isolated factors. In other words, Google treats page experience as part of what makes content helpful.

This view has a practical consequence. No matter how well you write, an unreadable layout, tiny fonts or endless unbroken paragraphs reduce the value of the text. Likewise, a fast and tidy page cannot rescue empty content. Consequently, you need both inside the same plan.

So when you produce content, look beyond keywords and check readability too. The readability checker helps you review basics such as sentence length. To see how strong pages in AI powered results organise their content, read my article on writing content for AI Overviews.

Which business website UX problems do I see most often?

After working with sites across many industries, I notice the same issues again and again. Still, none of them is technically complex. Yet because nobody spots them, they stay in place for years. The list below reflects my field observations, not the result of a statistical study.

• An auto rotating home page slider with five or six slides, each loading its own large image.
• A sticky header that covers a third of the phone screen, plus a promo bar stacked on top.
• Contact forms with unnecessary fields and a phone field that opens the wrong keyboard on mobile.
• Product catalogues offered only as PDF downloads instead of page content.
• Third party tracking codes that someone added years ago and nobody checks anymore.

What these issues share is that each one looks small on its own. Together, however, they hurt LCP, CLS and INP at the same time and weaken the first impression. Before you add a new feature, ask which existing elements actually earn their place. Quite often, the most effective improvement means removing something rather than adding it.

What should small sites without Core Web Vitals data do?

New sites and local business sites with modest traffic often see no data in the Core Web Vitals report. The reason is simple: the Chrome User Experience Report needs enough real visits to produce a meaningful assessment. This is not an error. In other words, the sample does not exist yet.

On such a site, work with lab measurements while you wait for field data. PageSpeed Insights and Lighthouse give you an approximate picture. In addition, opening your own pages on a slow mobile connection and watching how long the first screen takes to become useful works surprisingly well for small sites.

The cost of fixing things is also low. With one theme, a few plugins and a limited number of pages, you can build a clean foundation within a few days by following a checklist. Once traffic grows, field data appears and you can switch to tracking the real user distribution. So a lack of data is no excuse to postpone the work.

Which Search Console reports should you watch for SEO and UX?

Google's page experience documentation points directly to the Core Web Vitals report and the HTTPS report in Search Console. I also collect indirect signals from a few more reports, because user experience problems sometimes show up in click and impression data as well.

• Core Web Vitals report: groups URLs as good, needs improvement or poor, for mobile and desktop.
• HTTPS report: lists indexed pages that do not use HTTPS.
• URL Inspection: shows how Google sees the page, including a rendered screenshot.
• Performance report: a big gap in click through rate between devices can point to a mobile experience issue.

A word of caution. After you fix an issue and click "Validate fix" in the Core Web Vitals report, results will not arrive instantly, since the report waits for new real user data to build up. Patience, therefore, pays off here. For SEO and UX, regular report tracking beats any one time fix. In my SEO consulting work, I run this review as a monthly routine.

Which user experience factor should you invest in first?

With limited budget and developer time, you cannot fix everything at once. My order of priority depends on how many users a problem affects and on how much the fix costs. The sequence below is a starting point based on field experience, not a rule that fits every site.

1. HTTPS and redirect errors: they create trust and access problems, and fixing them is usually cheap.
2. Full screen popups and interstitials: often a single setting, with an immediate effect.
3. Broken mobile layouts: tap targets, overflowing tables, forms.
4. LCP: image optimisation and server response.
5. CLS: images without dimensions and late loading slots.
6. INP: usually needs developer effort, so start with a tag cleanup.

Still, I recheck this order with data on every project. For example, if the INP problem sits on the checkout page, it jumps to the top, because it means direct revenue loss. Put simply, priority equals the business value of the page multiplied by the severity of the issue. Site architecture also plays a role in deciding which pages matter most, and my article on category structure for large websites can guide you there.

What are the most common myths about page experience?

Most of the myths I encounter come from reading Google's documentation second hand. Here are the ones I hear most, along with what the documentation actually says.

"A Lighthouse score of 100 will put me in first place." No. Lighthouse is a diagnostic tool, and Google looks at real user data. On top of that, relevance always comes first.

"Bounce rate is a direct ranking factor." Google's page experience documentation does not mention such a metric. That said, bounce rate can help you diagnose problems. Still, it does not appear among the page experience questions Google publishes.

"The mobile test tool is gone, so mobile no longer matters." Quite the opposite. The tool disappeared, yet mobile display is still on the list.

"A beautiful design boosts rankings." Aesthetics alone do not count as a signal. What matters is whether the design makes the content easier to reach. That is why, if you plan a visual refresh, you should also follow the steps in my guide on protecting SEO during a website redesign.

Where do technical SEO and user experience overlap?

Technical SEO and UX are often two sides of the same code. For example, a page that renders its content only through JavaScript appears late for users and also makes life harder for crawlers. Similarly, long redirect chains keep people waiting and waste crawl resources at the same time.

Titles and descriptions also form another overlap. When the title in the search results does not match the page a user opens, that person goes back disappointed. Therefore, honest titles and descriptions that reflect the real page content are the first step of user experience, and it starts on the results page. You can preview how your title looks with the Google SERP preview tool.

In the AI era this overlap has grown wider still. Moreover, fast, clean and meaningful HTML serves people and AI crawlers alike. I cover the advanced side in my article on technical SEO after AI. Also, if you are building a new site, bring SEO checks into the web design process from day one.

What does a step by step SEO and UX checklist look like?

I use the following checklist when I first review a new client's site. It builds on Google's official questions and turns each one into a measurable check. You can work through it on your own site in the same order.

1. Note the poor URL groups for mobile and desktop in the Core Web Vitals report.
2. Open a sample URL from each group in PageSpeed Insights and read both the field data and the diagnostics.
3. Check the HTTPS report and your redirect chains.
4. Open the home page and your three highest earning pages on a real phone over mobile data.
5. Confirm that the headline and main content appear on the first screen.
6. Look for full screen popups, forced sign ups or layers that hide content.
7. List image sizes and formats, elements without dimensions and late loading areas.
8. Review your tag manager and remove tags nobody uses.

When you finish, you hold a prioritised to do list. Because SEO and UX alignment is an ongoing goal, repeat the same check after every major update.

How do you measure the business impact of UX improvements?

Green Core Web Vitals do not count as a business result on their own. Instead, the real question is whether the improvement changed visitor behaviour and sales. That is why I always place business metrics next to the technical ones.

My practical method works like this. First, I compare the four weeks before and after a change. Where possible, I also compare against the same period last year to reduce seasonal effects. In GA4, I look at engagement rate, form submissions and drop offs in the purchase steps. Meanwhile, in Search Console, I track mobile click through rate and average position.

I have to be honest here. Linking a ranking change to a single UX fix is rarely possible, since algorithm updates and competitor moves happen in the same period. So judge the improvement not by "did it lift rankings?" but by "did the same traffic produce more conversions?" That question gives you a measurable answer that matters for the business. If you need help with the setup, you can reach me through the contact page.

Conclusion: the page that satisfies users is the page Google looks for

Google's message on user experience is quite consistent. There is no magic signal, yet a good page experience is one of the things its core ranking systems try to reward. Core Web Vitals, HTTPS, mobile display, restrained advertising, non intrusive dialogs and a clear main content area form the official frame of that experience.

The lesson I take from my own work is simple. Treat SEO and UX alignment not as a one off optimisation project but as part of your site's standard maintenance. First come relevant, helpful content, then friction free access to that content. Consequently, when you take both steps together, search visibility and conversion rate move in the same direction.

If you are not sure where to start, run a short review with the checklist above. That way you can separate the issues that truly cost you visitors from the ones that only worry a score.
