What Ereferer does

Ereferer (legal entity SAS Ereferer, registered in Montreuil, France; SIRET 52281558800028) operates a two-sided marketplace for the buying and selling of sponsored articles and guest post placements, serving SEO agencies, in-house SEO professionals, and website publishers primarily in the SMB segment. Founded in 2010, the platform aggregates over 50,000 publisher sites across roughly 10 languages, with a stated 20,000+ active buyer base and inventory including premium domains such as Bloomberg.com and MarketWatch.com. Buyers access a filtering engine that ranks publishers on Trust Flow, Domain Authority, Traffic, TTF, WHOIS/ARCHIVE age, and backlink counts; transactions start at €10 per sponsored article, with Ereferer retaining a commission on each spread between buyer price and the 90% publisher payout (76.50% net after a 15% withdrawal fee).

The company's product surface extends beyond the core marketplace into a copywriting service (from €1.85 per 100 words, with SEO formatting, optional 123RF/Pixabay images, premium writer tiers, and 24-hour urgent delivery), a directory submission module covering 307 directories, a group purchase feature that splits guest post costs between two buyers, and a WordPress plugin that lets publishers auto-publish sponsored content via API key authentication with configurable categories and status rules. Distribution is purely self-serve product-led growth with free signup, multilingual UI, and organic/content marketing through an educational blog — there are no field sales, channel partners, or paid acquisition signals in the source data. The company is privately held with no disclosed external funding, acquisitions, or leadership changes.
