You can do some powerful discoveries by reviewing trending over time and analyzing ups and downs to know algorithm updates, unverified updates and other problems in the force. It’s a comparatively fast method to produce and can provide focus and direction for the consequent audit.
- Bing & Yahoo organic search is being popular over time. You might catch overall organic search trending down for a niche against just Google. I’ve experienced that earlier, as well.
- As soon as you see movement during dates without identified algorithm updates, search for those dates by Google. Let’s say, January 2014 Panda Update or September 2015 Google Algorithm Update. You may find a few posts written by some re-known bloggers.
- Take screenshots (You can use sniping tool if you are on a windows computer) whenever possible to highlight the drop and the equivalent algorithm update.
- Make certain that you take seasonality into account. There are a few sites that surge throughout Q4 due to the holidays, some that drop in summer months and so on. It’s essential to understand this before diving into the analysis.
- Don’t get occupied in the basic details of a specific hit. Concentrate on when the update happened and which algorithm update possibly will be the root cause. Remember, the SEO audit is where you will dive deeper into the site, find problems, document modifications to implement and more.
I suggest reviewing your SEO analysis report (similar to Google Analytics or Adobe Analytics), Google Search Console (using historical data if at all possible), Bing Webmaster Tools and third-party statistics like SEMrush, Searchmetrics and SimilarWeb.
