Google just started rolling out the so-called “mobile-first” index. It’s going to change the way that your site gets ranked in the search engine results pages (SERPs). Here are a things you need to know about the mobile-first index so that you can optimize your website accordingly.
Google crawls your site to add pages to its index. That is, it uses a bot to surf around your site like a real visitor and follows links on your pages.
In the past, Google crawled your site as a desktop user. Now, however, Google will crawl your site as a mobile user. That’s a distinction with a really big difference.
For starters, your website might present a completely different display to mobile users versus desktop users. In some cases, links that appear on the desktop version of your site might not appear on the mobile version. That’s bad because the Googlebot can’t follow links that aren’t there. As a result, your site might take a hit in the SERPs.
Keep in mind also that Google uses a number of ranking signals to determine where your site should land in the results list. If the bot finds that your site is hostile to mobile users or loads very slowly, you’re definitely going to lose rank.
The bottom line — when performing search engine optimization (SEO) for your site, start with optimizing it for a mobile audience. That’s the prime directive now.
the number of mobile users surpassed the number of desktop users a couple of years ago. If anything, Google is late to the game. In addition to that, Google says that there are more mobile searches than desktop searches. So it makes perfect sense that its bot should crawl pages as a mobile user.
