SEO Clusterizer vs Topvisor

SEO Clusterizer groups semantically similar search queries to support website structure and content planning. It provides eight clustering algorithms, including semantic analysis, hierarchical clustering, multilingual stemming, rare-word weighting, and tolerance for spelling variants. Its SERP feature groups keywords by overlap among ranking URLs, with results cached for 14 days. Content Analyzer scores pages across 20 quality factors and creates a content brief. The Force examines Google Top 10 competitor text and identifies missing terms. Inputs can come from Serpstat, Ahrefs, SEMrush, Google Keyword Planner, CSV, TSV, and TXT files. Exports include CSV, JSON, TSV, Markdown, and XLSX; JSON is described for developer and CMS integrations. Basic clustering runs locally in the browser, while premium AI, SERP, and content analysis run on the server and are not used to train models. Free costs nothing, Pro costs $29 a month, and Agency costs $89 a month.

Topvisor tracks search rankings across Google, Yandex, Yandex.com, Bing, Seznam, YouTube, App Store, Google Play and VK. Checks can target search locations and languages, with desktop and mobile results. Scheduled checks can email detailed reports, and projects can track up to 250 competitor sites; up to five competitors per project can be tracked for free. Teams can share projects with guest access and send selected reports to clients through guest links. Projects and checks and reports remain accessible when the account balance is zero. Projects and keywords are listed as unlimited, but checks consume account balance and only the latest check per day is stored. Connections include Yandex.Metrica, Google Analytics, Yandex.Webmaster and Google Search Console. Topvisor describes its API as free and unlimited on all plans for project management and data retrieval. The XS plan is free; paid plans start at $29 a month. Its privacy policy says personal-data databases are located in the Russian Federation.
