Serpier makes this page. Every fact about SEO.AI comes from SEO.AI's own website, and the facts on this page were last checked on . Sources are listed at the end.

Where Serpier is better

Buying a link is one step. Serpier also suggests which step to take next, and does it once you approve.

  1. 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.
  2. You click Hand over to Navi or I'll do it myself.
  3. Navi does the work, and you approve before anything is bought or changed. As your rankings, AI visibility and links change, new suggestions keep coming.

Method and what each row means

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. Every value links to its source, with the date we checked it. Serpier's facts follow the same rule and come from Serpier's own website.

Plans sold by the month show a price a month. A price for something bought by the item or once shows its unit, for example per article or one-off, and is never turned into a monthly price. A price with no unit is one where the company's own pages do not say what it is for. Prices 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. Some companies show other prices or currencies depending on where the visitor is, so the page says which visitor the prices were shown to.

Each value in the table is one of these, or the number or words the company uses:

Yes:
the company's own pages say the product has it.
No:
the company's own pages say it is not offered, or a complete plan table leaves it out.
Partly:
offered with a limit, written next to the value.
Not stated:
we could not find it on the company's own pages. It does not mean No.
Not public:
the company does not publish it, for example a price behind Contact sales.
