SEO guest posting services: what you are buying, what Google's policy says, and how to judge a provider

An SEO guest posting service places articles written on your behalf on other websites, usually with a link back to you. Two very different businesses sell under that one name. The first is a contributor programme: a writer with something to say pitches a relevant publication, the editor accepts it on merit, and the link is incidental to the article being worth publishing. The second is a link marketplace: a price list of sites that accept paid posts, sold by domain metric. Google's spam policies treat links in exchange for a guest post as link spam, so the second model is buying something that works against you. Before you shortlist a provider, decide which of the two you are commissioning, and make the brief say so.

This page covers buying and judging guest posting as a service. For the full picture of what earns links now, see link building.

What the policy actually says

Google's spam policies name link spam explicitly and include large scale article campaigns with keyword rich links in the examples. The policy also sets out the way to publish paid or exchanged links without breaching it: mark them with rel="sponsored" or rel="nofollow".

<a href="https://example.com/your-page" rel="sponsored">your anchor text</a>

That single attribute is the practical test of what a service is selling. A provider offering a link that passes ranking signals in exchange for money is offering a breach of the policy as a product. A provider placing genuine editorial contributions, where the publication decides on merit and sometimes removes the link, is doing marketing. Read any proposal with the attribute in mind and the ambiguity disappears.

The three things a service can actually sell you

What you get	Who it suits	What to check
Editorial contribution programme: pitching, writing and placing on relevant publications	Businesses with a genuine expert to put a byline on	Which publications, who pitches, who writes, the acceptance rate
Digital PR: original data, surveys or commentary offered to journalists	Brands that can produce something newsworthy	The data source, the angle, the target publication list
A list of sites that accept paid posts, priced by domain metric	Nobody building a business for the long term	Whether the site has real readers, and whether the link is marked

How to tell which one is in front of you

Ask these eight questions. The answers sort providers quickly, and a good one will enjoy being asked.

1. Name five publications you have placed on in my sector in the last six months. Then open them and read the posts. Real contributions read like the publication; placed ones read like a brief.
2. Who writes the article, and what is their subject knowledge? A named writer who can interview my team is a different product from a content mill.
3. What is your acceptance rate on pitches? Anything near a hundred per cent means the placements are bought, not accepted.
4. Do you pay the publication? A straight answer here tells you what you are buying.
5. How is the link marked? Sponsored or nofollow on anything paid.
6. Does the site have real readers? Check for a masthead, named editors, bylines with histories, comments, a newsletter, social accounts that people reply to, and whether the site publishes anything that is not a guest post.
7. What happens if the publication rejects the piece? Replacement, rework or refund, stated in the contract.
8. What do you report? Live URLs, publication dates, the anchor and the attribute on each link.

Avoid any service that quotes guaranteed placements by domain rating band, sells a monthly quota of links at a unit price, or will not name its publications before you pay. Those three are the reliable signatures of a marketplace wearing an agency's clothes, and a cheap bulk campaign is the most expensive link building there is once you have to clean it up. The tactics that hold up and the ones that cause problems are separated in backlink strategy.

What a brief for a good service looks like

• The expert. Name the person whose byline goes on the work and how much of their time you can commit. Thirty minutes of an expert on a call makes an article a publication will accept.
• The target publications. Ten to twenty you would be proud to appear in, chosen because your buyers read them rather than because of a metric.
• The subjects you can speak on with authority, and the ones you will not comment on.
• The pages you want supported, with the understanding that the publication decides the link.
• Approvals. Who signs off a draft, and in how many days. Slow approval kills more placements than weak pitching.
• Reporting. Live URL, date, anchor text, link attribute, and referral traffic where the publication is big enough to send any.

Judge the result on more than the link

1. Is the article still live three months later? Placements on sites that exist only to host guest posts disappear.
2. Did it send any referral traffic? A publication with readers sends some. One with none has told you what it is.
3. Does the page rank for anything itself? A host page nobody finds passes nothing of value.
4. Was the byline yours? Named author credit on a real publication is an asset you keep independently of the link.
5. Did a journalist or editor come back to you? One ongoing relationship is worth more than twenty one off placements. What makes a link worth having in the first place is covered in what is a backlink.

Doing it yourself, in four steps

In house guest posting costs time rather than money, and it produces better placements because the expert is in the building.

1. List twenty publications your buyers read. Trade press, industry newsletters, association sites, respected blogs, conference blogs.
2. Read their last ten articles and find the gap. Pitch the thing they keep almost writing.
3. Send a short pitch with three specifics: the argument, why you can make it, and what evidence you will bring. The structure that gets replies is in six backlink email templates.
4. Write the piece for the publication's readers, not for your pages. One link in the author bio and one in the body where it genuinely helps is the right ratio.

Asked and answered: SEO guest posting services

Is guest posting against Google's guidelines?

Publishing a genuine article on a relevant publication is normal marketing. Buying links in exchange for guest posts falls under link spam in Google's spam policies. The distinction is whether money or an exchange bought the link, and whether it is marked as sponsored or nofollow.

How much does a guest posting service cost?

Services priced per link are selling placements; services priced per article or per month are selling work. Ask for the price breakdown between research, writing, outreach and placement, which tells you where the effort actually goes.

Does a nofollow link have any value?

Yes. It puts your name and your argument in front of the right readers, it can send qualified traffic, and it is a citation that other sources quote. Treat the attribute as a compliance matter rather than a measure of worth.

How many guest posts do I need?

Fewer than any quota based pitch suggests. Five strong placements on publications your buyers read will do more than fifty on sites that exist to host them.

What is the difference between guest posting and digital PR?

Guest posting places your article under your byline. Digital PR gives a journalist something to write about and the coverage is theirs. PR is harder, slower and produces the stronger citations.

Should I use keyword rich anchor text?

Write the anchor the way a writer naturally would. A pattern of identical commercial anchors across many placements is one of the clearest footprints of a bought campaign.

Why the publication matters more than the link now

Sorting a paid link marketplace from a real contributor programme was always about the publication. It matters more now because assistants read publications. A guest post on a respected site in your field is something a model can quote, where a link on a thin network adds nothing it can use.

You can check a provider's claims: ask ChatGPT, Gemini and Perplexity who is recommended in your field and see which publications they cite. Those are the places to pitch. AI Knows Us gathers the cited sources across assistants for the questions you choose, which turns a vague outreach list into a short, ranked one.
