Google fights against spam content on websites 24/7 handling most spam removal from its index automatically using algorithms, although they do still examine some questionable documents by hand. The aim is to keep delivering its users the best, relevant, reputable search results.
There are 10 categories / types of spam Google look for:
- Unnatural links from a site
- Hidden Text / Keyword Stuffing
- User generated

- Spammy free sites & dynamic DNS providers
- Cloaking / Sneaky Redirects
