The backlink quality checklist.

Start with existence. A surprising share of link inventory fails here.

• 1. Google indexation. Search site:example.com in Google. Look at the result count and whether the homepage appears. Red flag: a handful of results or a missing homepage, meaning the site is deindexed or filtered. A link there passes nothing, whatever the metrics claim.
• 2. Organic traffic. Open the domain in Ahrefs Site Explorer or Semrush Domain Overview and read the organic traffic graph. You want stable or growing traffic, ideally high hundreds of monthly visits or better. Red flag: a cliff that lines up with a Google update; the site was hit and never recovered.
• 3. Authority against traffic. Compare DR or DA with that traffic figure. Red flag: DR 70 with 100 visits a month. Authority scores can be inflated with link schemes; real search visibility cannot.
• 4. Human editorial signals. Read the About page and two author pages. You want named staff, plausible bios, consistent bylines, dated articles. Red flags: no bylines, stock-photo headshots, and a prominent "write for us" page with a price list.

A site is judged by who it links out to, so judge it the same way.

• 5. Outbound link audit. Open five recent articles and note every external link. Red flag: links to casinos, CBD shops, payday lenders, or essay mills sitting in unrelated content. One is a warning. Two is a verdict.
• 6. Template detection. Skim ten articles for structure. Red flag: every post is roughly 700 words with three crossheads and exactly one external link in the middle. That uniformity is the signature of a link farm's production line.
• 7. Topical coherence. Read the category menu and the recent post list. Red flag: a "home improvement blog" publishing crypto, law, fashion, and travel. Sites that cover everything exist to sell links to anyone.
• 8. Outgoing anchor pattern. In Ahrefs, open the outgoing links report for the domain and scan the anchors. Red flag: exact-match commercial anchors ("best crm software", "buy gold ira") dominating the list. Journalism does not link that way; paid inventory does.

The last four checks apply to the specific page and link, not the domain.

• 9. Position on the page. Your link should sit in editorial body copy. Red flag: author bio, footer, sidebar, or a "partner content" widget. Position is a strong proxy for how much weight the link carries.
• 10. Link attributes. View the page source and find the anchor tag, or use a browser extension that highlights rel values. rel="sponsored" or rel="nofollow" is honest disclosure. Red flag: paying a dofollow price for a tagged link.
• 11. Page-level indexation. Search Google for the exact article URL. Red flag: the page hosting your link never gets indexed. Some sellers noindex link pages to hide the inventory from Google while still billing customers.
• 12. Referring domain trend. Open the site's referring domains graph in Ahrefs. You want steady growth. Red flag: sawtooth spikes and collapses, the fingerprint of churned paid links.

Treat checks 1, 5, and 11 as hard fails: any one of them means reject, whatever the price. For the rest, two red flags mean no. There is no negotiating a site back above the line because the placement is cheap; cheap is how failing inventory clears.

One more signal sits outside the twelve. A vendor who resists you running these checks has answered the only question that matters. We run the same verification on every placement we deliver and publish the results in live reporting, and our no-PBN policy exists for the same reason: a link you cannot verify is a link you should not pay for.

Quarterly is enough for most sites, plus any time rankings drop after a confirmed Google update. Export your profile from Search Console or Ahrefs, sort by newest first, and run the backlink quality checklist against the domains you do not recognize. Most failures need no action, since Google already ignores them. Patterns of failure, especially clusters from the same vendor era, are what a disavow decision is actually about.
