White hat vs black hat SEO: what is the difference?

The short answer

White hat SEO follows the guidance Google publishes and aims to help the visitor. Black hat SEO uses techniques that Google's spam policies name as manipulation, such as cloaking, hidden text, keyword stuffing and link schemes. Grey hat sits between the two. Google says violating sites may rank lower or not appear at all, and a manual action is reported in Search Console.

White hat vs black hat SEO: where the line is drawn

White hat vs black hat SEO is the informal way of separating search work that follows a search engine's rules from work that tries to get around them. No search engine uses either phrase. Google's own documents talk about spam policies, and about manual actions for sites that break them. The labels are still useful, because they describe a choice every site owner makes, often without knowing it, when they hire help or follow advice.

The table puts the two ends side by side. Real campaigns are rarely pure, so treat it as a line with two ends, not two boxes.

What Google says about spam

Google publishes spam policies for Google Web Search. It defines spam as techniques used to deceive users or to manipulate its systems into showing content prominently. The policies name specific behaviours, and the ones below matter most to a small business site. The full list is longer and Google updates it, so read the current spam policies on Google Search Central before you decide that a tactic is safe.

• Cloaking is showing one thing to people and a different thing to search engines, in order to manipulate rankings.
• Doorway abuse is making many pages that target similar searches and send visitors on to a page that is less useful than the one they wanted.
• Hidden text and links are content placed where visitors cannot see it, such as white text on a white background, text pushed off the screen or text at zero size. Google notes that accordions, tabs and text for screen readers are fine.
• Keyword stuffing is filling a page with keywords or numbers to manipulate rankings instead of writing for a reader.
• Link spam is creating links to or from a site mainly to manipulate rankings. Google says paid links are allowed when they are marked with the nofollow or sponsored attribute.
• Scaled content abuse is producing many pages mainly to rank instead of to help people. Google says it applies whether the pages are written by automation, by people or by both.
• Site reputation abuse is publishing third-party content on an established site to borrow that site's ranking signals.
• Expired domain abuse is buying an old domain mainly to borrow its past reputation for content that gives visitors little value.

Google says that a site breaking these policies may rank lower in results or not appear in them at all. Its automated systems, which include one called SpamBrain, look for spam, and people at Google can also apply a manual action. A manual action is reported to the site owner in Search Console, and the owner can ask for a review once the problem is fixed.

What black hat SEO looks like when it reaches your inbox

Most owners meet black hat SEO as an offer, not as a technique. The offer is worded in business terms and the method is left vague. The table matches common offers to the policy they touch and to a plainer alternative.

A promise of first-page rankings within days belongs on this list too, although it names no technique. It is covered in the last section.

Grey hat SEO and the questions that place a tactic

Grey hat SEO is a loose label for tactics that Google has not plainly banned but that exist mainly for search engines, or that are acceptable only if done a certain way. There is no official definition and no list that settles every case. The label helps because it moves the question onto intent and scale.

Guest articles show the problem. A useful article written for a publication whose readers care about the subject, with a link that fits the text, is ordinary publicity. Dozens of near-identical articles posted wherever they are accepted, each carrying a keyword-rich link, is a link scheme. The technique is the same in both cases. Purpose and scale are what differ. Automated writing tools work the same way. Using one to draft or tidy a page is not named as spam, but producing many pages mainly to rank is, however they were written.

Four questions help to place a tactic.

1. Would you do this if search engines did not exist?
2. Could you explain it to the customer who lands on the page, and to a reviewer at Google, without embarrassment?
3. Does it only work if nobody can see how it is done?
4. Is it repeated at a scale that no real customer would ever need?

A no to the first question, or a yes to the third or fourth, puts the tactic closer to the black hat end. A tactic that fails all four is not grey at all.

The risks of shortcuts

A shortcut carries two kinds of risk. One is a penalty. The other is that whatever it gained was never yours to keep.

Lower rankings or removal

Automated systems can demote or drop pages without telling anyone. Separately, a manual action appears in the Manual Actions report in Search Console. After the problems are fixed, the report has a Request Review option. Google's help pages say reviews can take several days to weeks and that lifting an action does not mean earlier rankings return at once. Check the current documentation for the process.

Gains that disappear

Google's page on spam updates says that after a link spam update, any ranking benefit that spammy links gave a site is lost, because its systems remove their effect. The benefit cannot be regained. The money spent on those links goes with it.

Cleaning up costs more than the shortcut saved

Repair means finding the links or pages involved, asking for removals, rewriting or deleting content and writing the review request. That usually takes longer than the shortcut saved, and it happens while traffic is down.

Problems you inherit

A site can inherit old tactics from a previous supplier, a purchased domain or a template. The penalty attaches to your site, not to the person who did the work. If rankings fell without an obvious cause, read the messages in Search Console and work through the checks in the guide to running a basic SEO audit yourself.

What white hat SEO involves from month to month

White hat work is quieter than the alternatives, and most of it can be seen on the page. A typical month might include checking that important pages can be crawled and indexed, rewriting a title so that it describes the page honestly, merging two pages that compete for the same search, adding real detail to a thin service page and asking a supplier or customer for a link they would be glad to give.

The guide to writing meta titles and descriptions shows how to describe a page without stuffing it with keywords. The guide to SEO strategy for a small business helps with choosing what to work on first.

Country and language pages follow the same principle. A separate page for a market is legitimate when it carries different information, such as another language, local delivery terms or different regulations. Copying one page for every country with only the name changed is the doorway pattern. The international SEO basics explain when separate pages are justified.

Questions that expose a black hat supplier

The easiest protection is to ask questions before work starts. A supplier using sound methods can answer every one of them in plain words.

• Which pages will you change, and what will change on them?
• Where will links come from, and will any paid placement be marked as sponsored?
• Who writes the content, and what do they know about our business?
• Will we have our own access to Search Console and analytics?
• What will the monthly report show, apart from link counts?
• Do you promise a ranking position?

The last question matters. Google's guidance for people hiring an SEO says that no one can promise a first-place ranking, and it advises caution with anyone who does. Paid ads do not change the answer. Google says that buying ads does not improve organic ranking, which the guide to SEO vs SEM explains.

Questions and answers

What is the difference between white-hat and black-hat SEO?

White hat SEO follows the guidance that search engines publish and tries to help the person searching. Black hat SEO uses techniques that Google's spam policies treat as manipulation, such as cloaking, hidden text and link spam. Between the two sits grey hat SEO, where intent and scale decide which side a tactic falls on.

What does Google say about spam?

Google's spam policies define spam as techniques that deceive users or manipulate its systems into showing content prominently. They name behaviours including cloaking, doorway abuse, hidden text, keyword stuffing and link spam. Google says violating sites may rank lower or not appear at all. Read the current policies on Google Search Central.

What are the risks of shortcuts?

The main risks are lower rankings or removal from results, a manual action reported in Search Console, and the loss of any benefit the shortcut gave. Cleaning up takes time, and Google says lifting a manual action does not bring back earlier rankings at once. Owners also pay for work that may later count for nothing.

Is grey hat SEO safe?

There is no official grey hat category, so no tactic is safe because of its label. A tactic that serves real visitors and would exist without search engines is usually low risk. One that only works if hidden, or that is repeated at a scale no customer needs, is closer to the spam policies.

Is using automated tools to write pages black hat?

Google's spam policies do not name the use of a writing tool as spam. They name scaled content abuse, which is producing many pages mainly to rank instead of to help people, and they say it applies however the pages are written. Check the current guidance on automatically generated content.

Can a previous SEO supplier's work still harm my site?

Yes. Links, pages and tactics left by a former supplier stay on your site, and any penalty applies to the site. Read the messages in Search Console, check the Manual Actions report and review the links and pages involved. If you recently bought the site, Google's review guidance says to mention that in a review request.
