To calculate the SEO metrics within our tools, we often use multiple data sources along with our own calculations.
Our three main data sources are:
Crawler data – For backlink metrics
Keyword data (from Google Keyword Planner) – For calculating search volume estimations
Search results data – For tracking ranking positions for both paid and organic data
Understanding where each metric comes from and how it’s calculated will give insights into both the advantages and flaws of that metric.
The core SEO metrics that we’ll cover in this module fall into 3 categories:
Our backlinks metrics: Ahrefs Rank, Domain Rating, and URL Rating
Our search traffic metrics: search traffic estimations and traffic value
Our keyword metrics: search volume, total number of keywords, organic traffic, traffic value, keyword difficulty, traffic potential, and parent topic.
For the rest of this module, we’re going to start building relationships between these databases and bring some context to seemingly arbitrary numbers.
