Links and authority

Backlinks are the most over-explained and least understood part of SEO. Every vendor sells a metric, every metric is a model rather than a measurement, and none of them come from Google. This hub explains what those numbers are built from, how far you can trust them, and what to do when two tools disagree by twenty points about the same domain.

The practical guides cover the part that actually moves: earning links that a person would plausibly click. Directory submissions, launch coverage, tool pages, comparison content and the handful of tactics that still work for a product nobody has heard of yet. They also cover what to avoid, because a bad link profile is much harder to unwind than it is to acquire.

Where a tactic is legacy advice that stopped working, the guide says so and says roughly when it stopped. Guest post networks, reciprocal link schemes and paid placements dressed as editorial are all still sold, and all still carry risk that is not priced into the sales pitch.
