Search Spam
Manipulations intended to deceive search engines (keyword stuffing, cloaking, doorway pages).
In brief
Search spam is any action intended to deceive search engines and artificially inflate a site’s rankings. Typical examples: keyword stuffing, cloaking (different content for bots and humans), doorway pages, link spam. Such methods violate search engine guidelines and lead to penalties.
Types of search spam
- Keyword stuffing — over‑repeating the same keyword in text, meta tags, or alt attributes.
- Cloaking — showing different content to bots and users.
- Doorway pages — pages created only to redirect or accumulate links.
- Link spam — artificially building low‑quality backlinks, buying links without proper attributes.
Penalties for spam
- Algorithmic filters — automatic ranking drops (Panda, Penguin).
- Manual actions — a human reviewer removes parts or all of the site from the index.
- Complete de‑indexing — a full ban.
How search engines fight spam
Algorithms (Panda, Penguin, SpamBrain) analyse thousands of parameters to detect spam. Human quality raters (assessors) check results and help train algorithms.
Search spam is not just a mistake but intentional abuse. Proven spam almost always leads to severe penalties.
