Mobile is not the future. It is the present.

A large share of Google searches comes from smartphones. If your site does not work well on mobile, you lose potential customers.

Searches from smartphones

Many Google searches come from smartphones. Your website has to work flawlessly on mobile to stay visible.

Mobile first

Google indexes the mobile version

Google uses the mobile version of your website for indexing and ranking (Google Search Central). The desktop version now comes second.

Speed

Slow pages lose visitors

If a mobile page takes too long to load, users leave. Google recommends a Largest Contentful Paint of no more than 2.5 seconds (web.dev).

Does SEO still matter?
More than ever.

AI search engines like ChatGPT, Gemini and Perplexity use the web as their source. Without strong SEO there is no GEO. SEO is the foundation, and GEO builds on it.

AI reads the web

ChatGPT and Gemini use indexed web pages as a knowledge source. Without SEO rankings, AI cannot see you.

E-E-A-T decides

AI systems prefer trustworthy sources. Strong SEO authority is the key to AI citations.

SEO + GEO combined

If you combine both, you get found on Google and can be named as an expert in AI answers.

Frequently asked questions about mobile SEO

What is mobile-first indexing?

Since 2021, Google uses only the mobile version of your website for indexing and ranking. If your mobile site is slow, cluttered or broken, your rankings suffer everywhere, desktop included.

Do I still need AMP for mobile SEO?

Since 2021, AMP is no longer required for the Top Stories carousel. Instead, we recommend a fast, responsive website with optimized Core Web Vitals. AMP can still make sense in individual cases, but most websites no longer need it.

Responsive or adaptive design: which is better?

Google recommends responsive design as the preferred approach. A single URL with a flexible layout is easier to crawl and index. Adaptive design (separate mobile URLs such as m.example.com) can cause duplicate content problems and needs extra configuration with alternate and canonical tags. For WordPress SEO in particular, responsive design is the best solution.

How fast should my mobile site load?

Google recommends an LCP (Largest Contentful Paint) below 2.5 seconds (web.dev). We aim for a mobile LCP below 2 seconds.

How do I test whether my site is mobile-friendly?

Google offers the Lighthouse report in Chrome DevTools and Search Console with its mobile usability reports. We also test manually on different devices and systematically check touch targets, viewport configuration, font sizes and the whole mobile user experience.
