In 2025, telling a client that "SEO is just about keywords and backlinks" is like telling them their restaurant's success is purely about the menu. Yes, the menu matters. But if the tables are dirty, the lighting is depressing, and customers bump into furniture on the way to their seats — the best menu in the world will not save you.
Google has spent the last several years building systems to measure the actual experience of visiting a website. The result is a set of ranking signals that are directly tied to your design and development decisions. Here is what is actually happening.
Core Web Vitals: Google's Experience Scorecard
Since 2021, Google officially uses Core Web Vitals as a ranking factor. These three metrics measure real user experience:
- Largest Contentful Paint (LCP): How quickly the main content loads. Google wants this under 2.5 seconds. A bloated hero image, unoptimised fonts, or a heavy slider will push this past 4 seconds — and you will lose rankings to leaner competitors.
- Interaction to Next Paint (INP): How responsive the page feels when a user clicks something. Too many JavaScript libraries running simultaneously is a common culprit.
- Cumulative Layout Shift (CLS): Whether elements jump around as the page loads. That annoying movement when an ad loads above your content? Google penalises that.
You can check your site's Core Web Vitals right now via Google PageSpeed Insights. A score below 50 is hurting you. Below 70 and you are leaving significant traffic on the table.
Mobile Usability Is a Hard Ranking Requirement
Google indexes the mobile version of your website first — this is what they call Mobile-First Indexing, and it has been the default since 2019. If your website looks fine on a desktop but has tiny text, overlapping elements, or buttons too small to tap on a phone, Google downgrades your entire site's ranking potential — not just on mobile searches, but across all searches.
In India specifically, where over 75% of internet traffic is mobile, a poor mobile experience is both a UX disaster and an SEO disaster simultaneously.
The Bounce Rate Signal
When a user arrives on your website and immediately hits the back button — that is a bounce. Google watches how many people return to search results quickly after visiting your page. If that number is high, it interprets your content as not satisfying what the user wanted.
Poor design causes bounces even when your content is excellent. Difficult-to-read fonts on a cluttered background, no clear indication of what the page is about, auto-playing audio, aggressive popups in the first three seconds — these are all design decisions that create bounces that damage your SEO.
Site Structure and Internal Linking
Google crawls your website like a map. If your pages are poorly interconnected — if there are orphan pages with no internal links pointing to them — Google either misses them entirely or assigns them lower authority.
A well-designed information architecture ensures that every important page on your site can be reached within three clicks from the homepage, and that related content is linked intelligently. This is not just good UX; it is how Google understands what your site is about and how credible each section is.
What To Do Right Now
- Run your website through PageSpeed Insights and note your Core Web Vitals scores
- Open your site on a budget Android phone — not on a laptop — and actually try to navigate it
- Check Google Search Console for "Mobile Usability" errors
- Look at your bounce rate in Google Analytics by page — pages above 80% need attention
If what you find is concerning, the good news is that most of these issues are fixable with a focused 4–6 week development engagement. We do exactly this work at Webzy — and the ranking improvements are often visible within 6–8 weeks of implementation.
