An analysis of six keyword research tools
Right keyword selection helps your content rank high in the search engines. Today we have multiple tools that can be useful in choosing the keywords that work there.
MOZ writer Jeff Baker has shared a comparative analysis of the six most accurate keyword difficulty tools. The analysis is presented with the help of Pearson Correlation Coefficient.
Baker says, “Between mid-January and late May, we ended up writing 55 blog posts each targeting 55 unique keywords. 50 of those blog posts ended up ranking in the top 100 of Google results.
We then paused and took a snapshot of each URL’s Google ranking position for its target keyword and its corresponding organic difficulty scores from Moz, SEMrush, Ahrefs, SpyFu, and KW Finder. We also took the PPC competition scores from the Keyword Planner Tool.
Our intention was to draw statistical correlations between between our keyword rankings and each tool’s organic difficulty score. With this data, we were able to report on how accurately each tool predicted where we would rank.
This study is uniquely scientific, in that each blog had one specific keyword target. We optimized the blog content specifically for that keyword. Therefore every post was created in a similar fashion”.
