Frequently asked questions

How many SEO agencies are listed in Spain?

FindSEO currently lists 8 SEO agencies in Spain. Listings are built from each agency's own website and can be claimed and updated by the agency.

How are agencies ordered?

By default, Featured agencies appear first and are always labelled as paid placement. After that, agencies are ordered by their verified FindSEO review score, weighted by how many reviews they have, so a single 5-star review doesn't outrank dozens of strong ones. Paying never changes ratings, reviews or awards.

Are Google ratings part of the FindSEO score?

No. FindSEO ratings come only from client reviews we've checked. Where available, Google ratings are shown separately with attribution and are never stored or mixed into our score.
