What is guest posting? A plain-English guide

Guest posting is writing an article that gets published on another website, usually with a short author bio or a link back to your own site. You get in front of someone else's readers, and the host gets free or paid content that suits its audience.

This guide explains what guest posting actually means, why businesses and site owners do it, how Google looks at the links involved, and how to do it without wasting money or getting into trouble.

Key points

Guest posting (also called guest blogging) means publishing your article on someone else's site.
People do it for three main reasons: reaching a new audience, building their reputation, and earning a link to their own site.
Some guest posts are unpaid and editorial. Others are paid placements, which Google says should carry rel="sponsored" or rel="nofollow" on the link.
Google's spam policies target links bought mainly to manipulate rankings, not guest posting as such.
A good guest post is relevant to the host site, genuinely useful and written by someone who knows the subject.
Paid guest posts are adverts, so UK ad rules on labelling apply too.

What does guest post mean?

A guest post is simply an article written by someone who is not part of the site's usual team. The "guest" is you, the writer or the business you represent. The "host" is the site that publishes it.

In practice, a guest post nearly always includes something that points back to the writer. That might be a byline with a link to your website, a mention of your company in the text, or a link within the article to a relevant page on your site. That link is often the main reason people want guest posts, which is where most of the confusion and risk comes from.

You will hear a few related terms. Guest blogging means the same thing. A sponsored post is a guest post the writer has paid for. An advertorial is a paid article that the advertiser controls, which UK ad rules treat as an advert. We explain those rules in our guide to the ASA and CAP Code.

How does guest posting work?

The basic process is the same whether you pitch editors yourself or use a marketplace:

Find a site whose readers would care about what you know. Relevance matters more than size.
Agree terms with the site owner: topic, length, whether there is a fee, and what kind of link is allowed.
Write the article, or pay the publisher to write it if they offer that. Follow the host's guidelines on tone and length.
Submit it with your target page and any link text you would like used.
The host edits and publishes it. They may change your wording or the link. That is their right.
Check the live post: is the link there, does it point to the right page, and is the post labelled properly if you paid?
Keep an eye on it. Posts and links sometimes get removed later, so check now and then.

For the full process, including pitching and writing, see how to do guest posting, step by step.

Why do businesses use guest posting?

There are honest, useful reasons to guest post, and they are not all about search engines.

Reaching new readers. A well-placed article on a trade blog or local news site puts you in front of people who already care about your topic. Some will click through. Some will remember your name.

Building credibility. Being published on a respected site in your industry is a signal to customers that you know your stuff. It is something you can point to in sales conversations.

Earning links. Links from other sites are one of the ways search engines discover pages and judge them. That is why guest posting sits inside wider link building. But the link is only worth having if the placement makes sense for real readers.

Referral traffic. A good link on a relevant page can send visitors for years. Even a link marked sponsored or nofollow can still bring people who click it.

Guest posting compared with other ways to get links

Method	What it is	Typical effort	Main risk
Unpaid guest post	You write for a site that accepts contributions, no money changes hands	High: pitching and writing	Low quality hosts that publish anything
Paid guest post	You pay a publisher to place your article	Lower: you pay instead of pitching	Unlabelled paid links that break Google's guidance
Digital PR	Pitching stories or data to journalists	High, and results vary	Little coverage for the work
Earned mentions	People link to you because your content or product is good	Ongoing, slow	Very little, apart from time

Is guest posting allowed by Google?

Yes, guest posting itself is fine. What Google objects to is links created mainly to manipulate rankings. Its spam policies list buying or selling links for ranking purposes as link spam. They also say that paid links for advertising or sponsorship are not a violation as long as they are qualified with rel="sponsored" or rel="nofollow".

Google has also written specifically about guest articles. In a 2017 post on large-scale article campaigns, it listed warning signs such as stuffing articles with keyword-rich links, publishing the same article across many sites, and using writers who don't know the subject. We cover the detail in what Google's link spam policy actually says.

The honest summary: a guest post that a real editor would publish for its readers is fine. A guest post that exists only to carry a keyword link is the kind of thing Google's systems are built to ignore or act against.

Paid or unpaid: what is the difference?

An unpaid guest post is an editorial decision: the host publishes your piece because it is good for their readers. A paid guest post is advertising. That changes two things.

First, Google expects the link in a paid post to be marked sponsored or nofollow. Google's guidance says these attributes generally mean the link is not followed for ranking purposes, so you should buy a paid placement for the audience, the brand exposure and the referral traffic, not on the promise that it will move your rankings.

Second, in the UK a paid post where you have control over the content is likely to count as an advert. The ASA says advertisement features should be obviously identifiable, with a clear label up front. The publisher and the advertiser share responsibility for that.

What makes a good guest post site?

Relevant readers. A plumbing firm gains more from a home improvement blog than from a general news site with no connection.
Real traffic. If no one reads the site, no one reads your post. Tool traffic estimates are rough, so ask the owner too.
Editorial standards. Look at existing posts. If every article is a thin piece with a casino link, walk away.
Honest labelling. A site that marks paid posts properly is protecting you as well as itself.
A track record. Sites that publish on time and keep links live are worth more than ones that disappear.

Third-party scores such as Domain Authority (DA) or Domain Rating (DR) can help you shortlist, but they are estimates made by SEO tool companies. Ahrefs, for example, describes DR as a relative measure of a site's backlink profile within its own database. They are not Google measures.

A worked example: a Leeds accountancy firm

Picture a small accountancy practice in Leeds that wants more enquiries from local sole traders. Writing for a national finance site might look impressive, but its readers are spread across the country and the competition for space is fierce.

Instead, the firm looks for a Yorkshire business blog and a UK site aimed at freelancers. It offers each one a practical article: what records a new sole trader should keep, and how the trading allowance works. The bio links to the firm's page for sole traders.

One placement is paid, so the publisher labels it as an advertisement feature and marks the link sponsored. The firm judges it on what it can actually see: did the article get read, did anyone click through, and did any enquiries mention it? It does not expect a ranking jump, and it does not pretend the paid link is editorial.

Mistakes to avoid

Chasing scores over readers. A high DR site in the wrong niche is rarely worth it.
Exact-match keyword links everywhere. Repeating the same money keyword as link text is a classic pattern Google warns about.
Recycling one article. Publishing the same piece on several sites helps no one.
Hiding that a post was paid. It risks breaking Google's guidance and UK ad rules.
Not checking the live post. Links get changed, removed or pointed at the wrong page.
Expecting guaranteed rankings. No honest seller can promise them.

What is guest blogging?

Guest blogging is another name for guest posting: writing an article that is published on someone else's blog or website, usually with a byline or link back to you.

What is the guest post meaning in SEO?

In SEO, a guest post usually means an article placed on another site that includes a link to your own. The link can help search engines discover your page, but if the post was paid for, Google expects the link to be marked sponsored or nofollow.

Is guest posting still worth it?

It can be, if the site is relevant and has real readers. Judge it on audience, credibility and referral traffic rather than expecting a ranking boost from a single link.

Do guest posts need to be labelled?

If the post is paid and the advertiser has control over it, UK ad rules expect it to be clearly labelled as an ad up front. Check the ASA's current guidance, as the detail can change.

How long should a guest post be?

Long enough to be genuinely useful to the host's readers. Many sites set their own minimum, so check their guidelines. A short, sharp piece that answers a question well beats a padded one.

Can I write guest posts for my own industry?

Yes, and that is usually the best place to start. Sites in your industry have readers who care about your subject, and editors are more likely to value your expertise.

Where to start

Guest posting works best when you treat it as publishing, not as link collecting. Pick sites your customers actually read, write something worth reading, be honest when you have paid, and check the result. If you want to compare UK sites side by side, with prices and track records in one place, start on the marketplace.
