The vetting checklist that separates real sites from link farms: traffic first, relevance second, outbound profile and footprints third, authority metrics last — with thresholds, instant disqualifiers and free tools.
Vetting is where link building campaigns are won or lost: a placement on a site Google ignores is worth exactly nothing, whatever its DR. This is the checklist we run on every prospect before pitching — traffic first, relevance second, outbound profile and spam footprints third, authority metrics last — plus the thresholds we use, the free tools that do the work, and the red flags that disqualify a site immediately.
Most guest post failures aren't bad content or bad pitches. They're links placed on sites that look fine in a metrics tool and are, in reality, link farms, expired-domain shells or publications Google stopped trusting years ago. BuzzStream's 2026 data found 96% of guest-post sellers on a major marketplace were low quality and 40% had zero organic traffic. Vetting is how you avoid being their customer.
Most people vet backwards: DR first, then maybe traffic, then a glance at the homepage. Authority metrics are the easiest thing in SEO to fake — buy an expired domain with old links and you have "DR 50" in an afternoon. Traffic can't be faked without Google's cooperation. So the checklist runs traffic → relevance → outbound profile → footprints → authority, and a site has to pass each stage to reach the next.
| Stage | Check | Pass | Fail |
|---|---|---|---|
| 1. Traffic | Organic traffic (Ahrefs/Semrush estimate) to the whole site and to the topic section you'd publish in | Stable or growing; traffic spread across many pages | Near zero; a cliff-edge drop in the history graph; all traffic to one unrelated page |
| 2. Relevance | Does the site cover your topic or your audience's adjacent interests? | Clear editorial focus; your article would fit the archive | Covers everything from crypto to parenting — a "general blog" is a seller |
| 3. Outbound profile | Who does the site link to from recent articles? | Relevant sources, a proportionate number of commercial links | Casinos, CBD, loans, essay mills, SaaS from every post; exact-match anchors |
| 4. Footprints | Sponsored/guest categories, author pages, about/contact, domain history | Named authors, real business details, history consistent with current content | A "sponsored" category with hundreds of posts; anonymous "admin"; expired-domain history in a different niche |
| 5. Authority | DR/DA via a DA checker; referring domains; spam score | Authority proportionate to traffic; diverse referring domains | High DR with no traffic; referring domains that are themselves spam |
| 6. Link terms | Will the link be in-body, contextual, followed/sponsored as agreed, permanent? Check with the dofollow checker on existing posts | Contextual in-body links in past contributed articles | Links only in author bios; all outbound links nofollowed despite "dofollow" promise |
| 7. Indexing | Are recent posts indexed? (site:domain.com and check a few URLs) | Recent posts appear in Google within days | Hundreds of posts, a fraction indexed — Google is already ignoring the site |
Numbers help, as long as they're paired. These are the organic-traffic minimums behind iNet Ventures' published tiers — a site has to clear the traffic floor and the authority floor to be placed at that tier:
| Tier | Min. organic traffic | Why |
|---|---|---|
| DR 10+ | 100+ | Proves the site is indexed and read, not just registered |
| DR 20+ | 250+ | Filters out expired-domain shells at the low end |
| DR 30+ | 500+ | Authority and audience both real — the workhorse tier |
| DR 40+ / 50+ | 1,000+ | Mid-tier authority should come with a genuine readership |
| DR 60+ | 2,000+ | High authority with low traffic is the classic inflated-metric signature |
| DR 70+ | 5,000+ | At this level, a real publication has real traffic — no exceptions |
Your own thresholds can differ; the principle is that traffic must scale with the authority you're paying for. A DR 60 site with 300 visits a month is not a DR 60 site in any sense that matters.
Sites that sell guest posts. Not automatically bad — plenty of real publications charge for contributed content. Ask whether it's a publication that also sells, or a seller pretending to be a publication. Real traffic, editorial standards and a proportionate amount of sponsored content distinguish them. Google's spam policies target the latter pattern.
New sites. Low traffic because they're six months old is different from low traffic because Google gave up. Check the trend, the content quality and the people behind it.
Big general publications. A national news site's "partner content" section can be a legitimate placement for referral traffic and brand visibility, but Google's site reputation abuse policy specifically targets third-party content riding on a host's signals — don't pay authority prices for a section Google may treat separately.
Expert quotes via Digital PR — your spokesperson quoted in DR 50+ publications.

Every check above applies to sites a vendor proposes — and a vendor who won't name sites before payment has failed vetting before you start. Ask for the URL, run the checklist, and reject anything that fails stage 1. This is exactly how we assess sites internally for blogger outreach and link inserts; our vendor red flags guide covers the supplier side.
Check five things in order: real organic traffic to the topic area, relevance to your subject, the outbound link profile (who else it links to), spam footprints such as a huge "sponsored" category or expired-domain history, and finally authority metrics like DR or DA. Traffic and relevance matter more than the authority number.
No. DA and DR are third-party estimates that can be inflated by buying an expired domain with old backlinks. A DR 50 site with no organic traffic is a red flag, not an opportunity. Always pair the metric with a traffic check.
There is no universal number, but a sensible floor is a few hundred monthly organic visits for entry-level placements, scaling with the authority tier you are paying for. iNet Ventures uses 100+ at DR 10, 500+ at DR 30, 1,000+ at DR 40–50 and 5,000+ at DR 70.
Look for sites with no clear purpose beyond publishing contributed posts, thin articles across unrelated topics, many outbound links to commercial sites in sensitive niches, an expired-domain history unrelated to the current content, anonymous authors and no real contact details.
Not automatically — many legitimate publications charge for contributed content. The question is whether the site is a publication that also sells, or a seller pretending to be a publication. Real traffic, editorial standards and a proportionate amount of sponsored content distinguish them.
iNet Ventures offers a domain authority checker, spam score checker, backlink analyzer, dofollow/nofollow checker and domain age checker, all free. Ahrefs’ free Website Authority Checker and Google itself (site: searches, cache, manual review) fill in the rest.
Vetting is tedious, which is why most people skip it and why most guest posts don't work. Traffic first, relevance second, metrics last — and if a site fails stage one, nothing else about it matters. Run the checklist on every prospect, every time, and your cost per link that counts will fall even if your cost per link rises.
