FAQ — Mobile Responsive Website
How do I know if my website is mobile responsive?
Test your site using Google’s Mobile-Friendly Test (search.google.com/test/mobile-friendly) and try browsing on an actual smartphone. If you need to pinch, zoom, or scroll horizontally, your site isn’t properly responsive.
What’s the difference between mobile responsive and mobile-friendly?
Mobile-friendly means the site works on mobile. Mobile responsive means it automatically adapts its layout to any screen size. Responsive is the current standard and better for both users and SEO.
Will making my site mobile responsive improve SEO?
Yes. Google uses mobile-first indexing, meaning your mobile site determines your rankings. A properly responsive site with good mobile speed will rank better than a non-responsive competitor.
How long does it take to make a website mobile responsive?
If starting with a non-responsive site, expect 2-6 weeks for a proper responsive conversion. If rebuilding, it’s part of the standard timeline. Some template-based sites can be made responsive faster.
Can I just create a separate mobile site?
Separate mobile sites (m.domain.com) are outdated and not recommended. They require maintaining two sites, can cause SEO issues, and don’t adapt to the wide range of screen sizes available today.
