White hat vs black hat SEO
White hat SEO earns visibility by making a site genuinely better for users and easier for search engines to understand: quality content, sound technical foundations, links earned through merit. Black hat SEO tries to game the ranking systems: buying links, hiding text, cloaking, spinning content, creating networks of fake sites. Grey hat sits in between — tactics not explicitly banned but against the spirit of the guidelines, such as aggressive guest posting purely for links.
Black hat tactics to avoid
- Buying links or participating in link schemes and private blog networks (PBNs)
- Cloaking: showing search engines different content from users
- Hidden text and links, keyword stuffing
- Doorway pages: many thin pages targeting variations that all funnel to one page
- Scaled content abuse: mass-generated pages (including AI-generated) with no value
- Site reputation abuse: hosting third-party content to exploit a site’s authority
- Expired-domain abuse: buying old domains to pass authority to unrelated content
- Fake reviews and review gating

Our free growth plan applies everything in this guide to your site: three opportunities, their value and the cost to win them. No obligation.
What happens if you are caught
Google applies manual actions (a human reviewer flags the site; you are notified in Search Console) and algorithmic suppression (systems such as the spam and helpful content updates reduce rankings without notice). Either can remove most of a site’s organic traffic overnight. Recovery takes months of clean-up and, for manual actions, a reconsideration request.
How to recover
- Identify the cause: check Search Console for manual actions; compare traffic drops against known update dates
- Remove or disavow bad links; delete or rewrite thin and spun content
- Fix cloaking, hidden text and doorway pages
- Document the clean-up and submit a reconsideration request if there is a manual action
- Rebuild with sustainable content and earned authority — see our audit service
Is negative SEO real?
Competitors pointing spam links at your site is possible but Google says its systems ignore most of it. Monitor your link profile and disavow if a genuine attack appears; do not panic over every odd link.
AI content and ethics
Using AI to help produce content is not against Google’s guidelines; producing content at scale primarily to manipulate rankings is, however it is made. The test is whether the content helps the person who lands on it.
FAQ
Frequently asked questions
Is black hat SEO illegal?
Not illegal, but it violates search engine guidelines and can get a site penalised or removed from results. Some tactics (fake reviews) can breach consumer law.
How do I know if my agency is using black hat tactics?
Ask how links are built and to see them. Unexplained spikes in links from irrelevant sites, suspiciously cheap pricing and refusal to share details are warning signs. See how to choose an agency.
Does Google penalise AI-generated content?
It penalises low-value content produced at scale regardless of how it was made. Helpful content assisted by AI is fine.
What is grey hat SEO?
Tactics that are not explicitly banned but push against the guidelines — a risk judgement rather than a clear line.
