Why bought links are a bad trade specifically
The economics are worse than they look. A bought link's value decays the moment the page selling it gets devalued, which is the predictable end state for any page whose business model is selling links. You are renting an asset from a landlord who is actively burning the building down.
Meanwhile the downside is asymmetric. A manual action against your domain affects every page you have, including the ones that were earning honestly. People who buy links usually discover this at the worst possible moment — after they have built a business on the traffic.
What to do instead, in rough order of payoff
None of this is clever. It is just the work, and it compounds in a way bought links never do.
- Be genuinely findable in the places your buyers already look — directories, comparison sites, and category listings in your niche. A nofollowed listing that sends ten interested people beats a followed link nobody clicks.
- Answer a question nobody else has answered properly. One page that is the best thing on the internet about a narrow problem will earn links for years without you asking.
- Publish the data you have and nobody else does. Original numbers get cited; opinions do not.
- Show up in the communities where your users already are, as a participant rather than a drive-by link dropper.
- Make it trivially easy to credit you — a clear name, an embeddable badge, a copy-pasteable description.
How to tell a useful directory from a link farm
The test is what they sell you. A directory that promises "do-follow, high DA" is selling ranking signals and will eventually be treated accordingly. A directory that sells visibility and nofollows everything is selling something it can actually deliver.
The second test is whether they show you real numbers. Any directory can claim traffic. Ask for the click count on a listing like yours, and see whether the answer is a figure, a range, or a change of subject.
