Hello All,

What does actually Mobile First Index means? Is it that on my desktop in google.co.uk when I will search my keyword then site will come on top whose Mobile performance is good as per google? and then what is Mobile Second Index?

Thanks!

Google is rolling out a new mobile-first index. This means Google will create and rank its search listings based on the mobile version of content, even for listings that are shown to desktop users. Google has started to use the mobile version of the web as their primary search engine index.

If you have a mobile site, then you need to make sure the content and links on the mobile site are similar enough to the desktop version so that Google can consume the proper content and rank your site as well as it did by crawling your desktop site.
