Adsy vs PressWhizz: Which Guest Posting Marketplace Is Better for SEO in 2026?

Buying backlinks through a marketplace is easier than contacting publishers one by one. The harder part is deciding which websites are worth paying for. A strong Domain Rating and an attractive price don’t tell you whether a site’s content is relevant, its traffic is stable or its audience matches your business.

Adsy and PressWhizz both let buyers choose publishers, review SEO metrics and buy placements without doing outreach. They differ mainly in the research tools they give you.

Two Marketplaces With Different Approaches

Adsy is built around guest posting and content marketing. Its advertised catalogue includes more than 150,000 websites, with over 20 filters, customer reviews and the option to supply your own article or have one written.

PressWhizz is an AI link-building marketplace with more than 72,000 publishers and over 31,000 niche-edit opportunities. Alongside standard filters, buyers can research existing articles, keyword rankings and competitor backlinks.

These are platform-reported figures, and catalogue size alone doesn’t decide which marketplace suits a campaign.

Publisher Quality: What Can You Check Before Buying?

Adsy’s strongest feature is its feedback system. Listings can show customer reviews (the platform advertises over 45,000), completion rates, average link lifetime, turnaround and examples of previous work, alongside Ahrefs, Moz or Semrush metrics. That helps buyers avoid publishers with a history of missed deadlines.

PressWhizz focuses on Ahrefs and Moz metrics, referring domains and organic traffic history. Traffic graphs show whether a site has kept its visibility or is declining, and a site with steady traffic and a clear editorial focus is often a better pick than one with high authority scores but erratic performance. On either platform, buyers still need to check that the site publishes relevant content.

Finding Relevant Websites and Existing Articles

Broad categories are a common problem: a site listed under “business” may cover dozens of unrelated subjects. Adsy narrows options with filters for category, geography, language, traffic and metrics, plus custom lists and saved-search notifications. PressWhizz offers Exact Category Match, which separates sites dedicated to a topic from those that cover it among others, and Favorite Portals for shortlists.

The clearer difference is research into content that already exists. Content Search on PressWhizz searches more than 30 million indexed publisher pages for articles mentioning your keywords. That makes it easy to find publishers already writing about your topic, or existing articles suited to a niche edit. Adsy supports link insertions but has no equivalent tool for finding individual articles across its network.

Ranking Keywords adds another route: it finds PressWhizz publishers already ranking in Google for chosen search terms, which can surface relevant sites that standard filters miss.

Managing Campaigns and Competitor Research

For agencies juggling several clients, both platforms help track history. Adsy offers projects, lists, favourites, allowlists, blocklists, filters for previously used sites and CSV/XLSX order exports. PressWhizz’s My Projects lets teams blacklist publishers and see which sites already link to a client’s domain before ordering again. Both support finding newly added sites; PressWhizz filters by the last one, three or six months or the past year.

PressWhizz also includes Competitors Backlink Research, covering up to three competitors. Buyers can see which publishers link to rivals, review them for relevance and quality, and shortlist them, all without leaving the marketplace. Adsy lets buyers import domains found elsewhere but doesn’t offer a built-in competitor workflow.

Pricing, Content and Delivery

Adsy offers two purchase options: Content Placement, where you supply the article, and Content Creation and Placement, where the publisher writes and publishes it for one displayed price. It also has publisher messaging and custom orders.

PressWhizz says its direct relationships with site owners help keep prices competitive, reduce rejections and speed up turnaround. Prices are shown upfront, a managed service covers larger campaigns, and the company reports adding roughly 1,000 to 2,000 new websites each week. Whichever you use, compare equivalent offers and confirm what the price includes, since writing or editorial requirements can add cost.

Link Protection After Publication

“Permanent” doesn’t mean protected forever. Adsy advertises permanent placements and monitors link presence for three months, and its average link lifetime data helps judge past reliability. PressWhizz includes a 12-month guarantee: if a link or page is removed in that period, it tries to restore the placement and refunds the order if it can’t. For agencies buying on behalf of clients, that longer protection is a meaningful difference.

Which Marketplace Is the Better Fit?

Adsy suits buyers who want a very large guest-posting catalogue, a simple choice between supplying content and ordering writing, and publisher reviews to guide decisions. PressWhizz suits buyers who research articles and keyword rankings before buying, mix guest posts with niche edits, study competitor backlinks or run repeat campaigns, and value a 12-month guarantee.

Final Verdict

Adsy is a well-established marketplace with a large catalogue, flexible content services and useful publisher reliability data. It is a good option for buying sponsored articles in a straightforward way.

For SEO agencies and businesses focused on relevant backlinks, PressWhizz is the stronger overall choice. Its research tools, campaign management and longer guarantee give buyers more control over where their links appear, which makes it the platform worth trying first.
