How to Vet a Link Seller: 8 Red Flags to Avoid

The link selling ecosystem is unregulated, unaudited, and full of people who will take your money and deliver something that looks like a backlink but functions like nothing — or worse, a liability. In iGaming especially, where the commercial value of links is high and the penalty risk for manipulative profiles is significant, buying from the wrong seller is a decision you'll be undoing for the next 12 months.

This guide gives you eight specific red flags to check before committing to any link placement or link seller. These aren't theoretical warnings — they're the patterns that repeatedly appear in audits of underperforming or penalised iGaming link profiles. Learn to spot them and you'll dramatically improve the ROI of every link building budget you spend.

Red Flag 1: They Lead With Domain Authority, Not Traffic

When a link seller's first sales point is 'DA 45, DR 38, TF 30' — a stack of third-party metrics — without any mention of organic traffic, treat it as a warning sign. Domain-level metrics are easy to inflate through reciprocal linking, purchased links, or legacy link profiles from years ago. Organic traffic from real users searching for relevant content is much harder to fake and much more relevant to the actual value of the placement.

A legitimate publisher should be able to tell you: how many monthly organic visitors the site receives, which countries they come from, and roughly what topics drive that traffic. If they can't — or won't — answer these questions, the most likely explanation is that the traffic numbers don't support the metrics they're leading with.

⚠️ Ask every link seller: What is the monthly organic traffic for this site, and what geography does it come from? If they can't or won't answer, walk away.

Red Flag 2: The Site Has Hundreds of Outbound Links on Every Page

Open the specific page where your link will appear and count the external links. A page with 80–200+ outbound links to diverse, unrelated destinations is a link farm page — it exists to sell links, not to serve readers. Links from these pages pass minimal value because Google devalues each individual outbound link as the total count increases (this is the 'link juice dilution' principle), and the page's pattern is identifiable as commercial link placement rather than editorial content.

The threshold: pages with more than 20–30 external links are worth scrutinising. Pages with 50+ external links across unrelated topics are link farm inventory. Pages with 100+ are essentially worthless as placements regardless of domain-level metrics.

Red Flag 3: The Content Is Clearly AI-Generated Without Editorial Review

Since the widespread availability of AI writing tools, a significant portion of link seller inventory has shifted to sites populated with AI-generated content published at scale. These sites have real domain metrics, real hosting, and sometimes real domain history — but the content provides no genuine value to any reader, which means Google's Helpful Content system increasingly filters it from competitive search results.

Signals of unreviewed AI content: sentences that are grammatically correct but semantically empty; articles that cover topics in the same structure and level of generality regardless of complexity; no author bylines, no dates, no editorial voice; and content that reads like it was written to hit a word count rather than answer a question.

A link from a page Google has filtered from competitive SERPs due to content quality passes degraded authority — and in some interpretations, association with a low-quality content network is itself a mild risk signal.

Red Flag 4: The Site's Traffic Is Geographically Misaligned

This is the most expensive and most common mistake in iGaming link buying — and it's invisible if you only check domain-level metrics. A site can have DR 48 and 15,000 monthly organic visitors, and still be completely worthless as a placement for a UK casino affiliate if 85% of those visitors are from the Philippines, India, or Eastern European markets with no intent to play at a UK-regulated casino.

Always pull the traffic geography breakdown before committing to a placement. In Ahrefs, go to the site overview and check the 'Top countries' breakdown. For UK, Australian, or North American iGaming sites, you want the referring publisher's traffic to be majority from Tier 1 English-speaking markets. For European markets, verify the traffic is from your relevant jurisdiction — a site with 90% German traffic is irrelevant for a site targeting Swedish players.

Red Flag 5: They Offer Links on Pages That Don't Exist Yet

'We'll create a new article for your link' sounds like a service. In practice, a brand-new article published specifically to host your link starts with zero page-level authority, zero traffic, and no indexing history. It will pass some domain-level authority in time — but it starts from zero, and new pages on link-seller sites often take months to be indexed because Google deprioritises crawling of domains that publish content at high volume without earning traffic.

This is meaningfully worse than a niche edit — an insertion into an existing, indexed, ranking page. If every placement a seller offers is new content, you're paying for link potential, not link value. Ask specifically whether niche edits on existing indexed pages are available.

Red Flag 6: Suspiciously Similar Backlink Profiles Across Their Inventory

Link seller networks — whether PBNs or link farms presenting as legitimate sites — tend to share infrastructure and link patterns. A tell: if you pull 5 of the sites a seller is offering and they share 40–50% of the same referring domains, you're looking at a network. Sites in a network link to each other for mutual DR inflation, which means their metrics are inflated by internal links rather than genuine editorial citation.

Check in Ahrefs: open the Link Intersect tool, enter 4–5 sites from a seller's inventory, and see how much overlap there is in their referring domain profiles. Legitimate independent publishers have diverse, non-overlapping backlink profiles. Network sites cluster.

Red Flag 7: No Author Attribution and No About Page

Sites operating as link farms rarely invest in the editorial infrastructure that legitimate publishers maintain. The most consistent signal: no named authors on articles, no About page explaining who runs the site, and no contact details beyond a generic form. This matters for two reasons.

First, Google's E-E-A-T evaluation specifically looks for author expertise signals — sites without them score poorly on quality evaluation, which means pages on these sites receive less trust and pass less authority. Second, it tells you something practical about the site's purpose: legitimate publishers invest in author identity because it builds reader trust. Sites that exist only to sell links have no incentive to invest in this.

For iGaming placements specifically, the absence of editorial attribution on a gambling content site is a particularly strong red flag — regulated gambling content in most markets benefits from clear editorial responsibility, and legitimate gambling media consistently maintains it.

Red Flag 8: The Price Is Suspiciously Low for the Claimed Metrics

Market rates for guest posts and niche edits in iGaming are relatively well-established. A DR 50 gambling site with 10,000 monthly organic visitors from UK traffic charges £250–£450 for a guest post. If a seller is offering DR 50 placements at £40–£60, one of the following is true:

• The DR is inflated and doesn't reflect genuine authority

• The traffic metrics are fabricated or geographically misaligned

• The site is a link farm with cosmetically acceptable metrics

• The placement will go on a low-traffic, low-authority subfolder rather than the main site

Genuine quality in iGaming link building has a real cost. The market has priced it accurately over time. Sellers operating significantly below market rate are almost always selling something different from what they're claiming — and the cost of the resulting poor placement (wasted budget, diluted profile) almost always exceeds the discount.

The practical rule: if a deal looks too good to be true in link building, pull the Ahrefs traffic report before paying. The discrepancy between claimed and actual metrics will almost always be visible in the data.

The 5-Minute Vetting Checklist

Run every link seller and publisher site through this checklist before committing to a placement:

Check	Pass / Fail criteria
Monthly organic traffic	3,000+ visits/month minimum — verify in Ahrefs or Semrush
Traffic geography	Majority from target market — not misaligned international traffic
Outbound links per page	Fewer than 30 external links on the placement page
Content quality	Named authors, real editorial content, not AI-generated filler
DR vs traffic sanity check	DR and traffic should roughly correlate — large gaps signal manipulation
Referring domain overlap	Less than 30% overlap with other sites from same seller
About page / editorial identity	Named team, contact details, clear publishing purpose
Price vs market rate	Within 30% of expected market rate for the claimed metrics

Any single fail on this checklist warrants further investigation before purchase. Two or more fails is a strong signal to decline the placement entirely.

FAQ

Q: Can a site pass all 8 checks and still be a bad placement?

Yes — the checklist eliminates the most common failure modes but doesn't guarantee quality. A site can have real traffic, clean metrics, and editorial content, but still be a poor topical match for your niche, have a declining traffic trend suggesting a recent algorithmic penalty, or be overpriced relative to the authority it actually passes. The checklist is a minimum bar, not a full vetting framework.

Q: How do I verify a seller's claimed traffic without Ahrefs?

Semrush's domain overview is a good alternative. SimilarWeb provides rough traffic estimates for sites with meaningful scale (usually 10,000+ monthly visits). For sites below that threshold, SimilarWeb data is unreliable — Ahrefs or Semrush organic traffic data is more accurate for smaller sites. If you don't have a subscription to either, ask the seller for a screenshot of their Google Search Console traffic — any legitimate publisher will have this and most will share it under NDA.

Q: Is it worth reporting bad link sellers to anyone?

Practically, no — there's no central authority for link building conduct. The most effective response is to document the discrepancy (screenshotting claimed vs actual metrics), request a refund on the basis of misrepresentation if the placement was already paid, and add the seller to a blocklist for your own future campaigns. Sharing experiences in relevant industry communities (Slack groups, forums) helps other buyers avoid the same sellers.

Q: Does LinksPulse vet all the sites in its inventory?

Yes — LinksPulse reviews every publisher site for organic traffic, traffic geography alignment, content quality, and niche relevance before listing. DR and Moz spam score are checked as entry filters, and sites with declining traffic trends or spam score flags above threshold are excluded. This pre-vetting removes the majority of red flag sites from your consideration set, though we still recommend running through your own checklist for high-budget placements.

Q: What should I do if I've already bought links from a seller with red flags?

Pull the full backlink profile of your site in Ahrefs and identify all placements from that seller. Check the traffic and quality of each one individually — some may be acceptable despite the seller's overall pattern. For placements that fail the quality check, add them to a disavow file in Google Search Console. Don't rush the disavow — only disavow links you're confident are harming your profile, not all links from a given seller automatically.
