Early in my agency days, I bought placements on sites that looked fantastic on paper — strong metrics, professional design, quick turnaround. The links did nothing: zero ranking movement, zero traffic. Some of those sites later turned out to be dressed-up link farms.
Here is the uncomfortable truth: the most expensive backlink is the cheap one that does nothing — or worse, the one that puts your site at risk. Whether you are buying a placement or earning one through outreach, vetting the opportunity is the highest-leverage hour in link building.
This is the exact checklist we run at Ourex.pro before we pursue any link.
1. Real, Stable Organic Traffic — Not Just a Metric Score
Domain authority scores can be inflated. Real organic traffic cannot be faked as easily. Pull the site's traffic trend over the last twelve months, not a single snapshot. What you want is stability or growth. Watch for the cliff: a site whose traffic fell off six months ago was probably hit by a Google update or is an expired domain wearing a costume.
2. Topical Relevance Beats Raw Authority
A link from a DR 70 cooking blog to your SEO agency is nearly worthless — and it looks unnatural. A link from a DR 35 marketing blog that actually ranks for SEO topics can move rankings. Check what the site ranks for. If its top keywords live in your niche or an adjacent one, the link makes sense. This is also why we are picky about the sites we pitch — our comparison of niche edits vs guest posts touches on why placement context matters as much as domain strength.
3. Read the Content Like a Human
Before you check a single metric, read three recent articles on the site. Would you be proud to have your brand appear there? Is there a real author with a real opinion, or is every post generic filler? Look for signs of life: genuine author bios, specific examples, comments from real readers, content with a point of view.
4. Inspect the Outbound Link Profile
This is the step most people skip, and it is the fastest way to spot a link farm. Look at where the site links out. If you see outbound links to casinos, adult sites, pharma spam, or dozens of exact-match commercial anchors to unrelated businesses, walk away. A healthy site links out to sources its readers would genuinely find useful. Your link will sit in bad company otherwise, and bad company is exactly what Google's spam policies on link schemes target.
5. Confirm the Placement Type Before You Commit
Not all placements are equal. A contextual link inside the body of a relevant article passes the most value. An author-bio link is weaker. A footer or sidebar link is barely worth having. Always confirm exactly where your link will appear before money or effort changes hands.
6. Verify the Site Is Actually Indexed
Search site:example.com on Google and look at recent posts. Are new articles getting indexed within days? A site whose content is not being indexed is either penalized, brand new, or technically broken — and a link on an unindexed page might as well not exist.
7. Check the Site's History
Run the domain through the Wayback Machine. Was this a completely different site two years ago? Expired domains get rebuilt with the old authority intact just long enough to sell links. Also check for sudden topic pivots — a site that wrote about fitness for five years and suddenly publishes exclusively about cryptocurrency has been repurposed.
8. Read the Monetization Footprint
A "Write for Us" page that openly advertises paid guest posts, pricing tiers, and turnaround times is telling you exactly what the site is: a link seller. A handful of clearly-marked sponsored posts is normal; dozens of guest posts per month from random authors in random niches is a marketplace. Our guide to finding niche edit opportunities yourself focuses on the opposite end — real sites that rarely sell links and therefore pass real value.
The Five-Minute Vetting Routine
When evaluating at volume, run this in order and stop at the first failure:
- Traffic trend — stable or growing over 12 months? If no, stop.
- Relevance scan — top keywords in your niche? If no, stop.
- Content read — three recent posts, real editorial standards? If no, stop.
- Outbound check — clean link neighborhood? If no, stop.
- Indexation — recent posts indexed? If no, stop.
Red Flags vs. Green Flags
Walk away when you see: traffic cliffs, expired-domain history, spammy outbound links, "buy guest post" pricing pages, dozens of guest posts monthly, no real author identities, content not indexed, sudden niche pivots.
Lean in when you see: steady organic traffic, topical relevance, named authors with expertise, engaged readers, selective publishing cadence, editorial guidelines that reject most pitches.
What Quality Actually Costs
Honest ranges: placements on decent real niche sites typically run in the low hundreds of dollars all-in; strong editorial sites cost more, and the best ones cannot be bought — they have to be earned through outreach. This is the economic case for doing outreach yourself: earned placements on real sites cost effort instead of cash. That tradeoff is the core of what our link building outreach service is built around. For a third perspective, Moz's link building guide covers the fundamentals well.
