Each one's way of doing it, and the point where it stops.
Competitive Research shows a domain's estimated organic and paid clicks, keywords and top pages; Competitor Comparison sets up to 3 domains side by side, and their keywords go to rank tracking or a Content Editor brief in one step. Where it stops: No free plan, a 14-day trial; a free website traffic checker needs no account.
Site Analysis lists any domain's organic and paid competitors, top pages, visibility and keyword dynamics; Keyword Gap shows what a rival ranks for that you don't, and batch analysis checks many domains at once. Where it stops: Domains Serpstat has not indexed, such as new or low-traffic sites, return little or no data; the Free account allows 10 searches a day.
Domain Overview, Organic Rankings, Keyword Gap and Backlink Gap show what rivals rank for and who links to them; Position Tracking follows up to 20 competitors per campaign. Where it stops: Other sites' total traffic, channels and audience need the separate Traffic & Market toolkit; Free users see only sample domains there.
Site Explorer shows a rival domain's estimated organic traffic, organic keywords, top pages, paid keywords and country split; Content Gap and Link Intersect compare several rivals with you. Where it stops: Ahrefs Free gives data only for sites you verify, so no competitor lookups; on Lite you check sites one by one.
Traffic Overview shows a domain's estimated organic traffic with a 24-month trend, then Keywords by Traffic, Top Pages and Similar Websites; keyword gap lists export to CSV. Where it stops: Free allows 3 searches a day and 2 competitors per project; ranked-keyword totals are monthly snapshots.
KWFinder lists the keywords a competitor's domain ranks for and runs a keyword gap against up to 5 rivals; SiteProfiler gives an authority snapshot and opens the rival's backlinks in LinkMiner. Where it stops: No traffic numbers for other sites; Basic shows 25 competitor keyword rows and 20 SiteProfiler lookups a day.
The Performance report shows your own real clicks and impressions from Google by query, page, country and device, the measured baseline you compare each competitor gap against. Where it stops: No competitor data at all; own verified sites only, 1,000-row tables, data 2-3 days late.
