Guest Blogging: How to Write for Other Sites Without Writing Yourself Into Google's Spam Policy

Same byline, opposite verdicts

Picture two roofers. The first writes 900 words for his state contractors' association on how to read a storm inspection report. The editor trims it, adds a headline, and runs it with a two-line bio that names his company. The second pays a stranger to place an article on a site that published pieces on payday loans, keto snacks and roof repair the same morning, with the words "best roofer in Dallas" linked to his home page. Both men have a guest post. Only one has marketing.

Google has said where the line falls, more than once. A May 2017 post, now on its Search Central blog, A reminder about links in large-scale article campaigns, says Google does not discourage these articles when they "inform users, educate another site's audience or bring awareness to your cause or company." The trouble is articles whose main purpose is building links. Asked directly in its September 2023 office hours, Google answered: "Yes, using guest posts for links is against our spam policies."

The link building hub explains what links do and what Google forbids, and how to get backlinks ranks guest articles against fourteen other methods. This page covers writing for someone else's readers, cleanly.

Google's paper trail on guest posts, document by document

Read together, Google's statements are consistent: the article is fine, the link bought or engineered through it is not, and writer and publisher share the blame.

Note the words "publishing or acquiring" in the 2021 post. A site that sells guest posts with followed links can be penalized as surely as the business that buys them. Google's spam updates page adds the quieter cost: once its systems neutralize spammy links, any ranking benefit is gone. If an old agency ran a guest post campaign for you, a backlink audit shows what is out there, and our white hat SEO guide explains how penalties work.

The legitimate guest post, and the link scheme in a nicer suit

The two kinds of guest post can look identical on the page. The difference shows in how they came about, what they say and who reads them. Google's 2017 warning signs double as a checklist for your own habits.

Google's spam policy also lists creating low-value content primarily for the purposes of manipulating linking and ranking signals. A 600-word rewrite of the top search result, shopped to any blog that will take it, fits that description whether or not money changed hands.

A guest post is an audition in front of someone else's readers. The link is the business card left on the way out.

Publications a local business can actually get into

The best places to write are rarely tagged "guest post opportunities." They are publications that already need practical material from people who do the work, and that your customers or referral sources already read.

To find more, search your topics with your city or trade added and look for sites that run bylined articles from outside experts. Our guide to Google search operators shows how quotes, site: and the minus sign narrow a search. If a site's "write for us" page lists prices or turnaround times, you have found a seller, and our page on buying backlinks explains what you would be buying.

Ten minutes of homework before you pitch

If Google treats a host as a link seller, your article becomes one more data point in its pattern. Vet each prospect first. This routine is our practice, not a Google rule.

1. 1

   Read three recent posts

   Would your customers find them useful? Is there an editor's hand in them, or do they read like copy pasted from a dozen sources?

2. 2

   Look at who writes them

   Real bylines with real credentials, staff and contributors you can find elsewhere, are a good sign. Anonymous authors on every topic are not.

3. 3

   Check the outbound links

   If every recent post carries two or three links to unrelated businesses, the site is selling them. Walk away.

4. 4

   Look for labels on paid content

   Honest publishers label sponsored articles and mark their links. A site with obvious paid content and no labels is a risk to everyone it links to.

5. 5

   Check for readers

   Comments, shares, a newsletter, a search traffic estimate in any SEO tool. A page nobody visits sends nobody.

6. 6

   Ask about the link policy

   Ask the editor how they handle contributor bios and links. A clear answer, including "we nofollow contributor links," is the sign of a real publication.

Our guide to high quality backlinks has a longer scorecard for judging any linking site, including how to spot a private blog network dressed as a magazine.

A pitch an editor can approve in one read

Editors know the pitch by heart: "I'd love to contribute a high-quality, unique article on a topic of your choice." It says the writer never read the publication. A pitch that gets a yes does the editor's thinking for them.

• Their name and one recent piece you read, with a sentence on why it was useful. Proof you are a reader, not a mail merge.
• One specific topic and a working title, not a menu of five.
• Why you: the jobs, cases or years that give you something the editor's staff cannot write.
• What their readers will be able to do afterward, in one line.
• Length and a date you will deliver by, then keep it.
• No link request. Offer the article. Let the editor raise the bio.

Follow up once, a week later, then let it go. Our guide to email outreach covers subject lines, follow-ups and the CAN-SPAM rules that apply to commercial email. When the yes comes, write the article to the standard in our guide on how to write an article: the editor's readers, the editor's style, your knowledge.

Who sets the rel attribute, and what it should say

The publisher owns the page, so the publisher decides how its links are marked. Google's documentation on qualifying outbound links defines three values: sponsored for links that are advertisements or paid placements, ugc for user-generated content such as comments and forum posts, and nofollow when the other values do not apply. Links marked this way will generally not be followed. Since September 2019, Google has treated all three as hints rather than hard rules. Our guide to nofollow links explains the HTML.

Anchor text belongs to the editor too. Your business name in a bio reads like a byline; "affordable roof repair San Antonio" in the middle of paragraph three reads like what Google lists as link spam. If a host offers to make the link "dofollow" for a fee, you have learned what kind of host it is.

So why write for a nofollowed bio link? Because the readers are real: people who hire you and people who refer you. The article also puts your name where search engines and AI answers read about businesses, which our page on brand mentions vs backlinks develops.

Paid articles, sponsored posts and the sites that accept them

Paying for an article is not forbidden. Google's spam policy says it understands that buying and selling links is a normal part of the economy of the web for advertising and sponsorship, and that such links are fine when qualified with nofollow or sponsored. Pay for the readers if the readers are worth it. Never pay for the link.

Paid content has a second rulebook. The Federal Trade Commission's native advertising guide for businesses (December 2015) says labels such as "Ad," "Advertisement," "Paid Advertisement" and "Sponsored Advertising Content" are likely to be understood, calls "Promoted" at best ambiguous, and says a company's logo or name alone is not likely adequate. An unlabeled paid article misleads readers as well as search engines. DataCram is not a law firm; if you advertise in a regulated field, have counsel review the placement.

If you run a site and the guest post requests land in your inbox, the rules apply from the other side. Google's 2017 post tells publishers to ask whether they know the person, whether the message fits their audience and whether the article is useful. A pattern of paid outbound links can bring the manual action called "Unnatural links from your site." Mark contributor links, label sponsored posts, and decline the casino-adjacent pitches, however polite. Link swaps between writers get the same scrutiny; see reciprocal links.

Counting what a guest post earned

Judge a guest post the way the publication's editor would: did readers care? A link count cannot answer that. These can.

• Referral visits from the publication in GA4's traffic acquisition report, and what those visitors did next.
• Calls and forms that mention the article, which means asking new customers how they heard of you and writing it down.
• Invitations that followed: a second article, a podcast, a reporter who found you through it.
• Signups, if your bio pointed to something worth subscribing to rather than your home page.
• Searches for your name, since a bylined article is a public record of expertise.

Guest writing takes hours most owners do not have. Our content marketing team writes those articles with you, under your name, and earning links and mentions is part of DataCram's monthly SEO programs, which start at $625 a month with no long contract. Before sending readers anywhere, make sure the page they land on deserves them; the free website audit checks speed, SEO, mobile, security and content and emails you the report.
