In their own words
Seonio Keyword Clustering
Seonio Keyword Clustering turns a seed keyword into a topic cluster based on live Google rankings. It compares keyword pairs by overlap among ranking pages, maps them as a weighted graph, and applies the Louvain algorithm to identify topic groups. Related long-tail variants can be grouped under one page, while encyclopedias, marketplaces, and reference sites are filtered before clustering to reduce false connections. Each cluster can show a primary keyword, combined search volume, and the pages currently ranking for it. Terms that do not fit a cluster are flagged separately with their search volume preserved, and the tool shows the top 10 organic results for each cluster head term. It runs on the web and offers API access. The product page includes 10 free searches per month without a credit card. Paid options listed include Starter at $10 a month, Pro at $20 a month, and Business at $40 a month, with lower monthly rates billed annually. Credits refresh at the start of each billing month and unused credits do not roll over. Reports remain active for 7 or 30 days depending on the tool.
