Grey-hat SEO

What grey-hat SEO means

Grey-hat SEO is an informal label for tactics that sit in an uncertain area: not clearly forbidden, but used mainly to game rankings rather than help people. Examples often given include buying expired domains to redirect, heavy reciprocal linking, aggressive keyword use in anchor text and mass-produced content with light editing. Many of these now fall within Google's spam policies.

What gets sites into trouble

• Accepting "grey hat" as a reassurance.
• Assuming a tactic is fine because it worked last year.
• Building your main business site on risky methods.
• Forgetting that the policies get updated.

A typical case

A provider offers a car valeting company "grey-hat links that are totally safe". They turn out to be paid placements on unrelated sites with keyword anchors. The owner checks Google's link spam policy, sees these match its examples and declines.

How to tell if you’re affected

When someone describes a tactic as grey hat, read Google's spam policies and see whether it matches any examples. Ask whether you'd still do it if search engines didn't exist. If the only purpose is rankings, treat it as risky.

Why it matters for a small site

"Grey hat" is often used to make risky tactics sound acceptable. Over time Google has written many of them into its policies, such as expired domain abuse and scaled content abuse in 2024. A small business has little to gain and a lot to lose from tactics that might be reclassified as spam later.

The label also makes it harder to hold providers to account. Asking for a plain description of what they'll do, rather than a category name, gets you a much clearer picture of the risk.
