- Navi, Serpier's AI agent, reads your website, SEO performance, AI visibility and link monitoring, and suggests what to do next, each with why it is there: for example ordering a placement from a shortlist of publishers to work on a keyword sitting just off page one, or fixing robots.txt, llms.txt, the sitemap or meta tags.

We read each company's own website: its pricing page, docs, help center, terms and announcements. Review sites, directories and articles about a company are never a source.

Prices are per month and exclude VAT, in the currency the company publishes. A price in another currency is also shown in EUR, at the ECB reference rate of 26 October 2026.
