A seven-point checklist for checking whether a paid backlink placement is real before you send the money, not after you find out it gets 11 visits a month.
"Paid $2,4k for a backlink on a page that got 11 visits that month." That's the actual title of a post on r/DigitalMarketing this week, where the poster says an agency sold them a link based on the domain's overall rating, on a site that's been around since 2011, without ever checking whether the specific page the link would sit on got any traffic. It didn't. This kind of story shows up often enough on r/SEO and r/seogrowth that it's clearly not a one-off: people are paying real money for placements based on a domain-wide number that says nothing about the one page their link will live on.
The metric you're being sold isn't the metric that matters
Domain Rating, Domain Authority, and Trust Flow all describe the domain as a whole. A site can have a strong domain score built years ago on content that no longer ranks, no longer gets visited, and no longer has any real audience reading it. One r/seogrowth thread asking how to judge whether a backlink is worth it got a direct answer: DR is only a rough filter, and what matters is relevance, real traffic, clean rankings, and audience fit, checked at the page level, not the domain level. A DR60 site can have exactly one page (its homepage, built years ago) driving all of that authority, while the interior page your link would sit on gets essentially nothing. If a seller only ever quotes you the domain number, that's the first sign they haven't looked any closer than you have.
The checklist to run before you pay
None of these checks require a paid tool subscription you don't already have, and all of them take a few minutes per placement.
1. Check the specific page's traffic, not the domain's. Ask the seller which exact URL your link will go on before you pay, then check that URL's own estimated traffic (most backlink or SEO tools that show domain metrics also break out per-page traffic estimates). If they can't or won't tell you the exact URL in advance, that's a red flag on its own; it means you're paying before you know what you're buying.
2. Check whether the page is indexed at all. Search site: followed by the exact URL in Google. If the page doesn't show up, no traffic estimate matters, because the page isn't eligible to rank for anything and your link isn't visible to Google's crawlers as a live, indexed citation.
3. Count the outbound links already on the page. Open the page and count how many other outbound links are already there. A guest post with three total outbound links is a meaningfully different placement than one buried in a resource page with 80 other links pointing out; the more links a page passes out, the thinner the equity each individual one carries.
4. Check whether the link is qualified as a paid link. View the page source (or use a browser extension that flags link attributes) and look at whether your link carries a rel="nofollow" or rel="sponsored" attribute. This sounds backwards, most buyers want a "dofollow" link, but it matters for a different reason: Google's own spam policy documentation states plainly that buying or selling links for ranking purposes is a link spam violation, and that Google "does understand that buying and selling links is a normal part of the economy of the web for advertising and sponsorship purposes," and isn't a policy violation "as long as they are qualified with a rel="nofollow" or rel="sponsored" attribute." A seller who insists your link will pass full ranking credit with no qualification is asking you to take on the exact risk Google's own documentation describes, not offering you a better deal.
5. Check whether the domain has a history that doesn't match its current content. Look up the domain's past content, an archive tool works for this, and compare it to what the site publishes now. Google's spam documentation names this pattern directly under "expired domain abuse": buying an expired domain and repurposing it to publish unrelated content primarily to inherit its old ranking signals, its own examples include a former government or nonprofit site now running affiliate content. A backlink seller flipping expired domains into generic guest-post farms is exactly the scenario Google wrote that policy for.
6. Check what else the page links out to. A single page linking to your legitimate SEO or business content alongside a handful of unrelated gambling, pharma, or replica-goods links is a bad neighborhood, even if your own link is fine on its own terms. Scan the other outbound links on the exact page, not just the domain's general niche.
7. Check the site's overall traffic trend, not just its current traffic. A site that had strong traffic a year ago and has been declining every month since may already be sitting under a manual action or an algorithmic demotion it hasn't recovered from. A domain-level traffic chart (most SEO tools show this as a free preview) takes seconds to check and tells you whether you're buying into a site on the way up or already on the way down.
What a "yes" looks like
A placement that clears all seven checks isn't guaranteed to move rankings, no single link ever is, but it at least means you're paying for something real: an indexed page, with real visitors, a reasonable number of other outbound links, transparent link qualification, a domain whose history matches its current content, a clean link neighborhood, and a traffic trend that isn't already heading to zero. That's a fundamentally different purchase than a domain-wide number and a promise.
Where this differs from what's already on this blog
This blog already covers what a backlink costs across the market, a pricing benchmark built from a 105,000-site study. That post answers "what should I expect to pay." This one answers a different question: "how do I check that this specific placement, the one someone is offering me right now, is worth paying for at all." One is about market-wide pricing data; this is about the due-diligence step that has to happen before any individual invoice gets paid, regardless of what the going rate is.
A directory listing doesn't need this seven-point audit, because there's no page-traffic guesswork or hidden nofollow tag involved: the listing itself is the placement, and what you see when you check it is what you get.
