How to Vet a Link Building Vendor: 12 Questions That Expose Inventory Quality

Every vendor has case studies. Success theater is the cheapest content on the internet, and polished traffic graphs tell you nothing about what your delivery will look like. Vendor quality, like backlink quality, is observable only operationally: how they source, screen, place, document, and stand behind their work. The twelve questions below are the ones we would ask — they force specifics, and specifics separate sellers of inventory from managers of quality.

Before the twelve: the meta-question to hold while reading answers. Whose judgment stood between the sites offered and your profile? Anyone can answer with specifics. Sellers of resale lists answer with vague nouns — and the vagueness is the answer.

1) Can I approve sites before content is written? (Right: yes, always. Wrong: 'you can trust our standards.') 2) Who writes the content and what's their background? (Right: named writers with niche experience. Wrong: 'our team.') 3) What's the delivery driver — inventory or outreach? (Right: an explainable mix. Wrong: silence.) 4) What happens if a link drops inside a year? (Right: written replacement terms. Wrong: 'rarely happens.')

5) How do you screen outbound-link neighborhoods? (Right: they can describe the process. Wrong: 'we check quality.') 6) Can I see the exact sentence around my link? (Right: yes, after placement, always. Wrong: it takes a week.) 7) Who owns the publisher relationship? (Right: direct wherever possible. Wrong: 'our partners.') 8) What share of delivery is pre-existing inventory vs active outreach? (Right: honest proportions. Wrong: 100% of anything.)

9) What's your indexation verification process? (Right: specific checks and timing. Wrong: 'it's in the report.') 10) Can you show me three placements in my niche you delivered in the last month? (Right: names redacted but verifiable. Wrong: ancient samples.) 11) What niches do you decline? (Right: at least a few — YMYL, adult, crypto-adjacent. Wrong: none.) 12) What would make you reject my order? (Right: anchor over-optimization, impossible deadlines, niche mismatch. Wrong: 'we'd never — we take everything.')

Response speed says little (anyone can answer an email quickly). Response density says everything: operational detail without being prompted for it, caveats offered proactively, pricing explained like cost accounting. The moments vendors reveal themselves are always in the unprompted corrections — telling you when your anchor plan is too aggressive, or when your niche is underserved by their inventory. That's a partner answering, not a checkout cart.

And the final test: order small first. Twelve questions or two hundred, your profile bears the proof at month three, not the website copy.

Should I ask for the site list before ordering? Yes — reputable vendors share the shortlist (often masked) before commitment. Refusal to preview inventory is a precedent you should carry into every interaction: keep walking.

What if the answers are all correct but the price is suspiciously low? Then the answers were rehearsed instead of true. Operational reality has costs, and vendors who can't itemize their price are selling someone else's corners.

Vet the operation, not the marketing: twelve operational questions, one small test order, and the discipline to scale only what survives ninety days.
