As a result, a number of technical items must be taken into consideration when doing an SEO audit to validate crawlability and indexability, as well as to maximize visibility in organic search results:
1. Mobile web crawling
Google has shared that a majority of its searches are now mobile-driven and that they’re migrating toward a mobile-first index in the upcoming months. When doing a technical SEO audit, it is now critical to not only review how the desktop Googlebot accesses your site content but also how Google’s smartphone crawler does it.
You can validate your site’s mobile crawlability (errors, redirects and blocked resources) and content accessibility (Is your content correctly rendered?) with the following technical SEO tools:
- Google page-level mobile validators: Google’s Mobile-Friendly Test and Search Console’s “Fetch as Google” functionality (with the “Mobile: Smartphone” Fetch and Render option) are the simplestand best ways to check how Google’s mobile crawler “sees” any given page of your site, so you can use them to check your site’s top pages’ mobile status. Additionally, Google Search Console’s “Mobile Usability” report identifies specific pages on your site with mobile usability issues.
- SEO crawlers with a ‘Smartphone Googlebot’ option: Most SEO crawlers now offer the option to specify or select a user agent, allowing you to simulate Google’s mobile crawler behavior. Screaming Frog SEO Spider, OnPage.org, Botify, Deepcrawl and Sitebulb all allow you to simulate the mobile search crawler behavior when accessing your site. Screaming Frog also lets you view your pages in a “List” mode to verify the status of a specific list of pages, including your rendered mobile pages.
- SEO targeted log analyzers: Last year, I wrote about the importance of doing log analysis for SEO and the questions that this would allow us to answer directly. There are log analyzers that are now completely focused on SEO issues, such as Screaming Frog Log analyzer (for smaller log files), Botify and OnCrawl (for larger log files). These tools also allow us to easily compare and identify the existing gap of our own crawls vs. what the mobile Googlebot has accessed.
