How to Choose an SEO Service Provider (12 Questions That Filter Out 90%)

What exactly will I receive? Which sites or site types will the links be on? What authority and traffic do those sites have — measured how? What does the completion report include?

A credible provider answers all four in a paragraph each. Watch for answers that substitute process talk ('we use white hat methods') for specifics. Methods are invisible; deliverables should be listable.

Can I see sample reports before buying? Will placements be checked live at delivery? What happens if a link doesn't match the package specs? Do you offer any live guarantee, and what's the window?

These test whether the seller ever looks at their own output. Providers who verify have sample reports ready on request. Providers who don't will explain why you shouldn't need to see them.

Do you guarantee rankings? (The only correct answer is no.) What's the realistic timeline to see movement? Which parts of your catalog do you think I should NOT buy? How do you handle it when a campaign underperforms?

The third question is the filter's sharpest edge. A seller willing to talk you out of a bad fit is a seller whose recommendations elsewhere mean something.

Marketplaces give you fixed packages, published prices and a replacement workflow — ideal for buying specific deliverables. Agencies bundle strategy with execution at retainer prices. Freelancers are the cheapest and the most variable.

None is wrong. Just match the channel to what you're actually buying: execution favors marketplaces, strategy favors agencies, and freelancers favor buyers who can manage quality themselves.
