Black-hat SEO
Manipulative tactics that violate spam policies.
What black-hat SEO means
Black-hat SEO means tactics that try to manipulate rankings in ways that break search engines' rules. Examples from Google's spam policies include cloaking, hidden text, keyword stuffing, link schemes, doorway pages, scaled content abuse, sneaky redirects and fake reviews.
What gets sites into trouble
- Believing "everyone does it, so it's safe".
- Hiring the cheapest provider without asking about methods.
- Copying tactics seen on competitors' sites.
- Ignoring problems inherited from a previous provider.
A typical case
A driving school's rankings jump after a provider adds hidden blocks of town names to every page and buys links from unrelated blogs. A few months later the site drops out of results almost entirely. Cleaning up takes far longer than the rankings ever lasted.
How to tell if you’re affected
View the source of your pages and search for text that visitors can't see, such as text the same colour as the background. Check Search Console's Links report for unrelated sites linking to you and its Manual actions report for warnings. Ask any provider directly whether they buy links or create pages purely for rankings.
Why it matters for a small site
Black-hat tactics can produce quick results, which is why they're still sold. But they risk algorithmic demotion or a manual action that removes your site from results. A small business depends on its website far more than the person who sold the tactic does, so the risk falls on you.
There's also a reputational cost. Fake reviews, hidden text and doorway pages can mislead customers as well as search engines, and some practices, such as fake reviews, are banned under UK consumer law too.
