SEMrush Tools for Mobile SEO: Mobile Databases, Performance Report and AMP Checks in Site Audit

Hello and welcome to our SEMrush SEO Toolkit course! My name is Ashley Ward, I'm a digital marketing strategist at SEMrush and a passionate digital marketer. I'll guide you through this course.

The mobile Internet has become increasingly popular, with more websites getting traffic from mobile devices than from desktop computers and laptops, thus enabling users to access and share information on the go. In 2018, Google reversed their search direction by switching to a mobile-first index, and since then it has used the mobile version of content for indexing and ranking. This makes mobile SEO crucial if you want to be sure that you're visible to your audience anytime, anywhere.

Leveraging SEMrush's Mobile Databases to Build Your Mobile SEO Strategy

And what does mobile SEO start with? Mobile databases, of course! So, when building your SEO strategy, you absolutely shouldn't neglect the mobile databases present in SEMrush tools and reports, especially if you're targeting mobile devices.

Now, let's move on and learn about the most important factors affecting your mobile SEO. Site speed is the first among them, because it's synonymous with user experience. With a high site speed, your audience will stay on your website longer, bounce less, and convert better. To help you keep your site speed under control and optimize it if needed, we've created a dedicated in-depth report in the SEMrush Site Audit tool - Site Performance.

Optimizing Your Website's Performance with SEMrush Site Audit

Let's explore the report. Go to the Site Audit Overview page, then click View details.

There are five widgets that help you quickly analyze how your website performs and find areas of improvement. Let's take a closer look:

  • First and foremost, the Page (HTML) Load Speed donut chart shows the distribution of pages by their load speed: fast, medium, slow, and very slow. The common recommendation is to have pages with load speed under 1 second.
  • The Average Page (HTML) Load Speed trend shows how your website's speed has changed over time.
  • The Number of JavaScript and CSS bar chart shows your pages' breakdown by the number of JS & CSS files they have, so that you can find pages with too many webpage resources.
  • The JavaScript and CSS Size bar chart shows your pages' breakdown by the total size of JavaScript and CSS files used on a given page, thus allowing you to identify the pages with too-large code files.

Click on any of the charts' elements to see a list of the corresponding segment's crawled pages, which you can then sort by page load speed, number of JavaScript and CSS files, or JavaScript and CSS size. You're also able to refine the list by applying more filters to discover the pages with the weakest performance.

Getting back to the report, you'll see a list of performance issues, by solving which you'll enhance your website performance. Also, if you have your Google Analytics account connected to the Site Audit, you'll see a notice for pages that take more than 1 second to become interactive among other performance issues.

Implementing AMP on Your Website

Apart from optimizing your website's speed, it also makes sense to implement AMP, which stands for Accelerated Mobile Pages, to make your website more mobile friendly. It is a Google-run technology which is based on stripped-down HTML, designed to deliver a better user experience thanks to its almost instant load speed. And if you already have it up and running, you might want to ensure it's working properly. Surprisingly, the Site Audit tool can help you with checking your AMPs' health too!

Facilitating AMP Implementation with SEMrush Site Audit

The good news is that Site Audit tests your AMP pages automatically, with minimal effort from your side. To ensure your AMP pages are given priority over other pages during the next crawl, check the Crawl AMP pages first checkbox in the crawl settings. After the audit is complete, go to the Issues page and see if any AMP-related checks are triggered.

Overall, Site Audit tests your AMP pages' health for more than thirty technical issues across four checks:

  • AMP HTML issues
  • AMP style and layout issues
  • AMP templating issues
  • AMP canonicalisation Issues

Finally, go to the Statistics tab and find the AMP Links widget to make sure that all of your pages that have AMP versions are linked to them with the rel=amphtml tag.

SEMrush Tools for Mobile SEO: Lesson Summary

Let's wrap it up. To conquer mobile SEO, you shouldn't take your website performance for granted, instead ensure your website's fast load speed and deliver a great user experience. Also, to keep up with the times, implementing AMP on your website would be a good idea. To avoid any issues related to site speed and SEO implementation, use the related checks within the Site Audit tool.
