Ethical SEO: optimisation versus manipulation

Every SEO tactic sits somewhere on a line between making a page easier to find and understand, and trying to make a search engine believe something untrue about it. Google's spam policies describe where that line is. Learning them protects sites from losing visibility, and it also clarifies what good optimisation is: work that would still make sense if search engines did not exist.

Why the line exists

Google's goal is to show searchers the most helpful results. Spam tactics try to win rankings without earning them, and they make results worse for everyone. Google fights this with automated systems, such as SpamBrain, that detect spam at scale, and with human reviewers who can apply manual actions. The consequences range from a page losing positions to a whole site disappearing from results.

The main spam policies

Google's spam policies list specific practices. These are the ones beginners are most likely to meet.

Policy	What it looks like
Cloaking	Showing Googlebot different content from what users see, for example a text-rich page for the crawler and an ad-filled page for people
Doorway abuse	Many near-identical pages, such as "plumber in [city]" for 200 cities, created only to rank and funnel visitors elsewhere
Hidden text and links	Text in the same colour as the background, positioned off-screen or hidden behind images, to add keywords
Keyword stuffing	Filling a page with repeated keywords or lists of locations so it reads unnaturally
Link spam	Buying or selling links that pass ranking credit, excessive link exchanges, large-scale guest posting for keyword links
Scaled content abuse	Producing many pages mainly to manipulate rankings with little value for users, whether by automation, people or both
Site reputation abuse	Publishing third-party pages on a trusted site mainly to exploit its ranking signals, such as unrelated coupon pages on a news site
Sneaky redirects	Sending users somewhere different from what search engines were shown

The list in Google's documentation is longer and includes hacked content, malware, scraping, thin affiliate pages and user-generated spam. Read it end to end once; the descriptions are short and concrete.

Links: the rules most often broken

Links between sites are a ranking signal, which makes them a target for manipulation. The rule is simple: links that pass ranking credit should be earned editorially. When a link is paid for, sponsored or part of an advertising deal, mark it with rel="sponsored". Links in comments and forums should carry rel="ugc". rel="nofollow" remains acceptable for both.

<a href="https://forum-user-site.example/" rel="ugc">user's website</a>

Buying a sitewide footer link on an unrelated blog network is link spam. Earning a link because a journalist cited your original research is exactly how the web is supposed to work.

Manual actions and recovery

If a reviewer finds a violation, Google applies a manual action and reports it in Search Console's Manual actions report. The report explains the issue and whether it affects specific pages or the whole site.

How recovery from a manual action works.

To recover, fix the problem on every affected page, then submit a reconsideration request from the same report, explaining what was wrong and what you changed, with evidence. Moving to a new domain or buying more links does not help and often makes things worse.

Automated demotions from spam updates work differently. There is no request to submit. Google's systems reassess sites over time, so recovery comes from removing the violating practices and waiting for the systems to recognise the change.

A simple test for any tactic

Before using a tactic, ask three questions. Would I be comfortable explaining this to a Google employee? Does it help the people visiting my site, or only search engines? Would I still do it if search engines did not exist? A tactic that fails these questions is usually covered by a spam policy, even if you cannot yet name which one.
