Google in their latest update announced that they are now primarily focusing on mobile-first indexing and they are planning to shift to mobile-first indexing for all websites by September 2020. As per their analysis stated in their update, 70% of all sites that currently appear in their search results have already been shifted to this new category. They have also made it clear that they will be shifting the remaining sites to this new indexing method as and when their systems identify that the sites are ready for the same.
So what does this mean? It means that there will be a significant increase Googlebot’s crawling of the web, primarily the smartphone Googlebot. According to Google they will update their index for each site’s mobile version and there will be a variation in time depending on the domain of each website. This doesn’t necessarily mean that Google will stop using its traditional desktop Googlebot but the frequency will decrease and most of the crawling for Search will be done with their mobile smartphone user-agent.
It is absolutely no surprise for SEO veterans as Google had been working on this for the past four years and we (as in the world of the internet) have come a long way and our preferences have widely shifted from desktop to mobile viewing. Google started its mobile-first indexing process long back in 2016 and we had plenty of time to get ready for this.
Some key pointers for optimizing for mobile-first indexing are:
- On-page content is the same on mobile and desktop versions
- Meta data is the same on both versions
- Structured data is the same on both versions
Apart from the above pointers the top priority for mobile-first indexing is responsive web design. Google also prohibits the usage of mobile specific URLs (also known as “m-dot”)because it primarily causes issues and confusion for viewers and search engines alike.
