Almost every link that ends up being a waste of money was identifiable as a waste of money before anyone paid for it. The metrics were public, the red flags were visible, and the vetting step just didn't happen - usually because someone was moving fast through a vendor's spreadsheet of five hundred domains. This is the checklist worth slowing down for.
Start with traffic, not authority scores
DR and DA are the first numbers everyone quotes and the easiest numbers to inflate. A site can hold a DR of 60 on the strength of links it earned years ago while its actual search visibility has collapsed. Organic traffic is much harder to fake, which is why it's the first thing to check.
- Pull the organic traffic trend for the last 12–24 months, not the current snapshot. A steady line or gentle growth is what you want.
- A cliff-shaped drop usually means a core update or a penalty found the site before you did. Whatever caused it, you don't want your link on the wrong side of it.
- Check where the traffic comes from. A "US lifestyle blog" whose visitors are 90% from unrelated geographies is telling you something about how that traffic was acquired.
Read the outbound links like a ledger
The fastest tell that a site sells links indiscriminately is its outbound link profile. Open five recent posts and look at what they link to. Casino, CBD, essay-writing, and payday loan links sitting inside a parenting blog aren't editorial decisions - they're invoices.
Volume matters as much as category. A site publishing thirty "guest posts" a month, each with two or three dofollow external links to commercial pages, is operating a link farm with better typography. Search engines are demonstrably good at spotting this pattern, and links from those pages carry the neighborhood with them.
Would this content survive without the links?
Read two or three articles the way a human would. The question isn't whether the writing is brilliant - most of the web isn't - it's whether the article has any reason to exist beyond the link it carries. Thin 600-word posts that circle a topic without saying anything, stock intros, and paragraphs that exist purely to justify an anchor are the signature of a site built for sellers, not readers.
Also check whether real categories exist and are maintained. A blog whose "Finance", "Health", and "Travel" sections all began on the same day, with the same author byline, was assembled to sell placements across every niche at once.
Red flags that end the conversation
- The domain changed hands recently and the new content has nothing to do with its link history - a classic expired-domain rebuild.
- No named human anywhere: no author pages, no about page, no editorial trail.
- The site appears in a public "guest post marketplace" list at three different prices from three different resellers.
- Indexed pages are falling month over month, which means search engines are actively losing trust in the site.
Make vetting a one-time cost
The real reason vetting gets skipped isn't laziness - it's that teams re-vet the same domains over and over because nobody wrote the verdict down. The fix is boring and effective: keep a single inventory of domains you've already vetted, with the metrics, the price you were quoted, and the date you checked - ideally in software built for managing link building rather than a spreadsheet. Vetting a domain once per year is diligence. Vetting it once per order is overhead.
That's the model BuildLinks is built around: a shared domain inventory your whole team orders from, so the vetting work one person does in March is still paying off in November.
