Keyword Clustering Tool


The clustering tool automatically segments your keywords into relevant groups based on TOP-10 of Google and Yandex search engines. The tool generates and sends automated queries to search engines and then matches webpages from search results to each keyword. If the search engine returns the same webpages for different keywords and there are several matches for those, they will be banded up together (clustered). Keywords that revealed no matches in TOP-10 of search results are grouped into a separate group named Stray keywords.

Each webpage may have a pool of target keywords. The Keyword Grouping Tool allows to create relevant groups of target keywords to run up to top-rate SEO performance.

Methods of keyword clustering


SOFT


SOFT Clustering
The Clustering Tool picks the most popular keyword and compares TOP 10 search results for this keyword with TOP10 results for other keywords by the number of matching URLs in TOP 10. If the number of matching URLs matches the selected grouping level, these keywords are banded up together. All keyword within a group will be related to the most popular keyword, but they will not necessarily be related to each other (will not necessarily have matching URLs).

MODERATE


MODERATE Clustering The Tool picks the most popular keyword and compares TOP10 search results for this keyword with TOP10 results for other keywords by the number of matching URLs in TOP 10. At the same time, it compares all keywords to each other. If the number of matching URLs matches the selected grouping level, these keywords are banded up together. Each keyword within a group will have a related keyword with matching URLs. But two different pairs of keywords will not necessarily have matching URLs.

HARD


HARD Clustering The Tool picks the most popular keyword and compares TOP10 search results for this keyword with TOP10 results for other keywords by the number of matching URLs in TOP 10. At the same time, it compares all keywords to each other and all matching URLs in the related pairs. If the number of matching URLs matches the selected grouping level, these keywords are banded up together. All keywords within a group will be related to each other and will have the same matching URLs.

Clustering level


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

A chance to have 1-2-3 matching documents in SERP is much higher than having 9-10 matching documents (actually it's almost all pages in TOP-10). That's why clustering with a higher clustering level produces more groups with fewer keywords in every group. On the opposite, if you selected 8-9 or 10, you'll get lots of groups with a small number of relevant keywords in each of them. There are some exceptions, but they are uncommon.

You can change a clustering level to re-group keywords only within seven days after clustering.

Keyword clustering


To run the keyword grouping follow the below steps:

  1. Go to the Keywords page.
  2. Import or research keywords.

  3. List of imported keywords
  4. Press on the toolbar.
  5. In the pop-up window pick a search engine, a language, a location, and a grouping level*.

    Clustering settings
    The tool will group your keywords based on the preferences you set. If you haven't added keywords, they'll be grouped.

  6. Press Start.

During the keyword grouping, your interface will be locked.

Clustering in progress
Estimated time of keyword clustering for 5000 keywords is 10-15 minutes.

Clustering result
Once the tasks are processed, you'll get a complete keywords structure.

Please notice, that keyword grouping will switch off all keyword groups (they Rank tracker tool will ignore them when running ranking reports). To turn on a group, click on a red spot in the left corner of the group or press On all groups in the Notification Center, in the right-upper corner, on the toolbar.
