Competitors in Surnex are a **per-project list of domains**, maintained on the [Competitors](/competitors/add) page. ## Where competitor data appears Their position against yours, keyword by keyword. Who dominates AI answers for your topics. Sources AI cites about them and not you. [Backlink gap](/backlinks/gap) also compares competitors, but takes its domains as ad-hoc input on its own page rather than reading this list. ## How competitor data is collected Competitors aren't crawled or monitored as projects in their own right. Their data is a by-product of the collection Surnex already does for you: * **Positions** are read from the same search results page as yours during a [rank check](/tracking/overview). Same keyword, same location, same language, same moment — so the comparison is genuinely like-for-like. * **Backlink and AI data** is looked up against your project's [collection schedule](/projects/data-collection). Two consequences follow. Comparisons are always same-day rather than stitched together from separate lookups. And a competitor only has data for keywords **you** track — adding a competitor doesn't reveal what else they rank for. To see a competitor's full keyword profile, use [Domain Keywords](/keywords/research) on the Keywords page, which works on any domain. ## Competitors vs. domain analysis Two different tools that people reach for interchangeably: | | Competitors list | [Domain overview](/domains/overview) | | ------- | ------------------------------- | ------------------------------------ | | Scope | Your tracked keywords | The whole domain | | Ongoing | Yes, collected on schedule | One lookup at a time | | Answers | "Who beats me where I compete?" | "How strong is this site overall?" | Use domain analysis to decide **whether** a domain is worth adding, then add it to the competitor list to track it over time. ## Limits * Competitors are per project. A domain you compete with across several projects has to be added to each. * Up to **10** can be seeded at [project creation](/projects/add). Adding them afterwards on the Competitors page has no stated cap, but every additional domain widens the comparison table. * There's no competitor-level alerting. Nothing tells you when a competitor overtakes you; check the [comparison table](/tracking/competitors) or your own [ranking alerts](/tracking/alerts) for the drop.
