Unancor review

This review is based on Unancor’s public pages and third-party ratings, checked on 4 October 2026. The rating out of 10 is the editor’s own judgement.

How it works

Unancor is a Spanish marketplace and SEO service. Advertisers buy sponsored posts with contextual links in Spanish-language blogs and news sites. The public link building page does not show a catalogue. It asks you to fill in a form and promises contact within 24 hours, so the buying process starts with a conversation.

The site reports a database of more than 10,500 active media, more than 20,000 clients and over ten years of experience. It names large Spanish brands among its customers and well-known news outlets among its media. A footer note says the company received co-financing from the European Regional Development Fund. The pages we read do not give a legal entity or address.

On the publisher side, Unancor says each site is reviewed by hand, usually within 24 to 48 hours, and that traffic is verified with Google Analytics or Ahrefs data. More than 100 writers produce the sponsored content. Publishers set their own rates, can turn down proposals and decide whether a link is followed.

Pricing

Unancor publishes no prices. Its publisher page says it takes zero commission from publishers, who keep 100 percent of the rate they set, and that advertisers pay separate platform fees. The size of those fees is not stated. It also says it has paid more than €2.5 million to publishers.

Without a price list, you cannot compare Unancor with other marketplaces until you have a quote. Publisuites, the other Spanish marketplace we have reviewed, lets you start with a €10 top-up. For typical costs in the market, see our lesson on link building in Spain.

The guarantee

We found no guarantee on the public pages: no minimum time a post stays online, and no refund or replacement terms. Ask for these in writing with your quote.

Public ratings

Unancor’s Trustpilot profile is unclaimed and shows a score of 1.8 from 16 reviews, checked in October 2026. Every review gives one star. Most are from publishers who say they were not paid for published articles, some for months or years, and that emails and phone calls went unanswered. A few mention high prices and system errors.

These are reviewers’ claims, not our own findings. They matter to buyers as well as publishers: a publisher who is not paid has little reason to keep your article online. Sixteen reviews is a small sample, and the profile has no positive review to balance it.

What to check before ordering

1. Get terms in writing. Price, link type, labelling and how long the post stays live.
2. Vet each site. Verified traffic is a good start. Add the checks in how to vet a publisher.
3. Start with one order. Confirm it is published and stays up before committing a larger budget.
4. Monitor. Check the post monthly. Our lesson on how to track backlinks shows how.
