Mobile-First Indexing

Mobile-first indexing means that Google will include the mobile version of your website as the starting point of Google’s list of the index and it will become the ultimate criteria on which the ranking of your website will be determined. Once you monitor the crawlbot traffic on your site you will see a market increase in the traffic on your website from the Smartphone Googlebot and the pages’ cached versions will be basically the mobile version of your page.

Mobile-first indexing can be better understood if we understand what indexing actually means. It is the process of increasing the usability of your website by making it more user-friendly.  By the process of Indexing search engines like Google make a copy of your webpage in a certain format which is beneficial to help in the proper ranking algorithm.

It is termed “mobile-first” since it is not confined to mobile-only index. In case any website doesn’t have a user-friendly mobile webpage then its desktop version is taken into consideration for indexing.

However, the lack of user-friendly mobile webpage does have a negative impact on the ranking of their webpage. Naturally, in this scenario a website with a user-friendly mobile webpage will receive a potentially higher ranking even for the desktop users.

Now the questions that arise in this scenario are:

What if I Don’t Have a Mobile Webpage?

According to Google, not having a mobile webpage, responsive or mobile friendly website then In this case, Google will take it upon itself to crawl your desktop webpage but your ranking will affect in SERPs result because google consider your website as a poor user experience in comparison to mobile friendly websites.

However, if you have a mobile webpage you need to make sure that links available on your mobile webpage coincide with the links on your desktop version. Otherwise Google will be unable to consume the exact content and wouldn’t be able to rank your webpage by the process of crawling like it did to your desktop version.

What Problems Might I Face if I Have Different Contents on The Desktop and Mobile Webpage?

Now, if your site doesn’t have a device type redirect or if it doesn’t feature rel=alternate and canonical tags setup, then you might entail the chance that the Google ranking system will check the content only on your mobile webpage and will not check the check the content present on your desktop webpage.

Hence it is recommended to have the same content on both your mobile and desktop webpage, otherwise Googlebot will face a difficulty to discover the high-quality content present on your mobile webpage, leading to the decrease of the rankings of your webpage.

You can see with this simple example.

Content is like water and if you put water in any shape or size, water will take their shape and size. So content is important in both version of websites, and same content will be on both websites.

Will This Affect The Rankings of The Web Pages?

No, if your website is mobile friendly, this should not change the overall ranking of the websites. However, a small change is expected but it is yet too soon to predict anything about the rankings. The main goal of this change is not let indexing change have a large impact on the current rankings.

However, if your mobile webpage has lesser and poor quality content as compared to that present on your desktop webpage then you can potentially face a threat to have a lower ranking. That’s’ why Google always recommends the webpage owners to have the same content, page-by-page on their desktop and mobile webpage so that the rankings remain unchanged.

It might potentially lower your rankings.  If you wish to hide certain content from your mobile webpage in order to save space, then it will no longer be an issue as then the content would be seen in the same light as if the content was loaded in a fully visible manner. However, the content should be still crawlable.

This is an incredibly mobile-friendly ranking host. However, if your webpage is not mobile friendly, Google will not even take it into consideration for ranking.

In the previous index method, the desktop content was indexed and was utilized to feature the listings for both mobile and desktop users. This process is followed by the use of a friendly ranking system which boosts the content to increase its ranking in the Google’s mobile listing. Contents which aren’t mobile-friendly do not function well in this ranking system either.

In this new method, mobile content first gets indexed and is then used to show the listings both on the desktop and the mobile web pages. Then the mobile-friendly pages are boosted to have a mobile-friendly ranking.
