SEO Finds in Your Server Logs, Part 2: Optimizing for Googlebot
Posted by timresnik
This is a follow-up to a post I wrote a few months ago that goes over some of the basics of why server log files are a critical part of your technical SEO toolkit. In this post, I provide more detail around formatting the data in Excel in order to find and analyze Googlebot crawl optimization opportunities.
Before digging into the logs, it’s important to understand the basics of how Googlebot crawls your site. There are three basic factors that Googlebot considers. First is which pages should be crawled. This is determined by factors such as the number of backlinks that point to a page, the internal link structure of the site, the number and strength of the internal links that point to that page, and other internal signals like sitemaps.
Next, Googlebot determines how many pages to crawl. This is commonly referred to as the “crawl budget.” Factors that are most likely considered when allocating crawl budget are domain authority and trust, performance, load time, and clean crawl paths (Googlebot getting stuck in your endless faceted search loop costs them money). For much more detail on crawl budget, check out Ian Lurie’s post on the subject.
Finally, the rate of the crawl — how frequently Googlebot comes back — is determined by how often the site is updated, the domain authority, and the freshness of citations, social mentions, and links.
Now, let’s take a look at how Googlebot is crawling Moz.com (NOTE: the data I am analyzing is from SEOmoz.org prior to our site migration to Moz.com. Several of the potential issues that I point out below are now solved. Wahoo!). The first step is getting the log data into a workable format. I explained in detail how to do this in my last server log post. However, this time make sure to include the parameters with the URLs so we can analyze funky crawl paths. Just make sure the box below is unchecked when importing your log file.
