Clustering level

Clustering level - is a minimum number of matches (clustering degree) required to trigger grouping of two keywords. For example, you've selected a grouping level 2 - the tool will look for two matching documents in SERP and band up such keywords together.

Matching URLs A chance to have 1-2-3 matching documents in SERP is much higher than having 9-10 matching documents. That's why clustering with a lower clustering level produces less groups with more keywords in every group. On the opposite, if you select level 8-9 or 10, you'll get many groups with a few keywords in every group.

You can change a clustering level to re-group keywords only during seven days after clustering. Re-grouping costs $0.003 per 100 keywords.
