This is a very powerful tool that can show you not only ways to improve your On-Page SEO for a keyword, but also show how to improve your website in general.
The first column shows the Ranking Factor.
The next three columns (namely Top 3, Top 5 and Top 10) will always show the average value from the top rankings returned by search engines.
The next column will show the values for the webpage you entered (in the screenshot we compared it against gsa-online.de).
The rest (indicated by #1, #2, #3 … #10) will show the values for the particular website returned on the search query.
A red color means you should try to change this value, yellow suggest a change but considers this as not important for ranking and a green value shows it's fine as it is.
Everything you see here is a suggestion based on the analysis of the top rankings for this keyword. It's no fixed suggestion such as
“a keyword must be present in XYZ amount of <h1> TAGs”
, but instead this suggestion is always different and orientates on the ranking currently seen.
You see an explanation of all colors and icons at the lower status bar.
At the very bottom you see a description of the ranking factor, what it is for and what should be changed in detail to improve your SEO.
Since there are so many ranking factors, it might be a good idea to filter them to your needs.
Use the filter box at the top to only show factors with a certain term in it. In the sample below we see that speed was used to only show ranking factors that influence the speed of a webpage.
The “Compare Against” sub-menu will let you choose against what you want to compare your website against.
The “Measure with” sub-menu let's you choose how the comparison should be done (average, mean, min, max,…).
By using “Configure Sites” you can remove or add certain websites to your comparison.
The “Clear Cache” will make sure that the latest version of a website is downloaded instead of using some cached information.
There are a couple of extra analyzes you can turn on:
—-
Ranking factors who are not present on all of the websites are hidden by default (Hide unused Ranking Factors). Showing them might give you even more ideas.
There is an option called “Use Filter” which will be let you ignore certain ranking factors previously edited with Edit Filter. You can also use the right mouse click on them to filter them out.
Edit nGram Filter will fine tune how the nGram extraction is performed. That nGram topic is discussed below.
Edit Stop Words will decide what should be stripped from front/back of a found keyword or what should be ignored completely.
A nGram analysis is performed to find keywords that might influence your ranking.
There are basically 3 types that will be shown in the table:
Obviously the term SEO is shown as most important between the search results in the sample above.
