The SEO Value score allows you to measure the importance of a position or its movements. It corresponds to the estimated value of an SEO position.
It’s more useful to track the SEO value rather than the average rank. The SEO value allows you to measure the ranking evolution by taking into account the importance of keywords. For example, it will significantly increase if you’ve gained a position on a very important keyword. On the contrary, it will barely change if you gain a lot of positions on keywords with a weak potential.
You can use this score to measure your Return on Investment (ROI) by calculating your budget and the time spent, and comparing it with the SEO drops.
Data regarding keywords (volume and CPC) are updated every month and this can impact the SEO value that's why you can see variations at the beginning of the month.
The SEO Value is calculated according to our algorithm calculation. It takes into account different factors such as rank, type of keyword, search importance, AdWords competition, etc
To summarize: the SEO Value is the amount of money you have saved in AdWords to retain the same number of visitors you have with your current position in the search results.
