SEO Competition Tool
Understand how difficult a keyword may be to rank for based on key indicating factors. Moz’s Difficulty score takes into account the Page Authority (PA) and Domain Authority (DA) scores of the results ranking on the first page of Google’s search engine for the given query. It also intelligently modifies for projected click-through-rate (CTR) of a given page (putting more weight on high-ranking, more visible pages and less on low-ranking, less visible pages). The algorithm also accounts for newer pages on powerful domains that may have DA scores but not yet assigned PA values.
Volume Score
Predict how much search volume a keyword will receive with over 95% accuracy. Moz combines data from multiple sources to build our keyword Volume algorithm. We then place keywords into the most accurate ranges rather than applying a single number, capturing fluctuation in traffic due to market seasonality and other trending factors.
Opportunity Score
While Difficulty and Volume are great indicators of a keyword’s potential to rank high, with the new features Google has added into the SERP landscape, another important score is necessary to consider — Opportunity score uses an averaged CTR algorithm to build this useful metric and apply it based on the features seen in Google’s results pages. Results pages that have very few non-traditional ranking features and are more similar to the classic “10 blue links”-only model will have very high Opportunity Scores. Results pages that have many features — like images, ads, news results, answer boxes, knowledge graph panels, etc. — will have much lower Opportunity scores.
