Guest Post Red Flags: 12 Signs a Site Is Not Worth Buying

This checklist shows you the guest post red flags I look for before placing a client’s link, how to check each one in a few minutes, and which ones should stop an order outright.

How do I know if a guest post site is good?

A good guest post site has a clear topic, real readers who come from search or other sources, named authors, and editorial standards that reject weak or off-topic content. If you would happily send a customer to read it, that is a strong start.

After more than 5000 orders across Adsy, Legiit, NicheRanker and other marketplaces, I have learned that metrics alone fool buyers. A site can show a high authority score while its organic traffic has fallen to almost nothing. So I start with the site itself: open the homepage, read the latest five posts, and ask whether a real audience would want them.

Google’s spam policies also matter here. The site reputation policy in Google’s spam policies covers third-party pages published on a host site mainly to benefit from that site’s ranking signals. Sites that sell space for anything to anyone are exactly the ones where that risk is highest.

The publisher’s behaviour tells you as much as the site does. Watch how they answer simple questions. A good publisher asks about your topic, may reject an angle that does not suit their readers and explains how sponsored content is labelled. A weak one replies within seconds with a price list, accepts any niche, offers “permanent dofollow” without being asked and pushes you to buy in bulk. I have also learned to be careful with sellers who refuse to share the exact domain until after payment. A site you cannot vet is a site you should not buy.

What are the 12 red flags to check before buying?

The twelve red flags below cover content, traffic, links and the publisher’s behaviour; I check all of them before any order, and the table shows how to check each one and how serious it is.

One medium flag is not a reason to reject a site. Two or more high flags usually are. Flag 9 deserves special attention: Google’s link spam policy lists buying links that pass ranking credit as a violation, and says paid links should be qualified with rel=”sponsored” or rel=”nofollow”. A publisher who promises the opposite is selling you a risk.

How do I check if website traffic is fake?

You check for fake traffic by looking at the shape and source of the traffic rather than the headline number. Real traffic follows the topics of the site and the countries it writes for; fake or inflated traffic rarely does.

These are the checks I use, all available in common SEO tools:

• Keyword fit. Look at which keywords bring traffic. A gardening blog ranking mainly for celebrity names or unrelated brand terms is suspicious.
• Country fit. A UK local news site getting most visits from countries it never covers needs an explanation.
• Trend shape. Natural traffic moves gradually. A vertical spike followed by a cliff often points to a short-lived tactic or an algorithm hit.
• Page spread. If one or two pages account for nearly all traffic, the rest of the site, where your post would sit, may get almost none.
• Screenshot proof. Ask for a recent Google Search Console or analytics screenshot with dates visible, and compare it with third party estimates.

No single check proves fraud. Together they show whether the traffic is likely to include people who could read your article.

What metrics matter when choosing guest post sites?

The metrics that matter most are topical relevance, organic traffic trend, indexing of recent posts and the number of outbound links per post; third party authority scores are useful filters but poor final judges.

Authority scores such as DA, DR or AS are calculated by tool vendors, not by Google. They can be pushed up with cheap links, and they do not show whether a site is still visible in search. I use them only to shortlist.

My order of priority is simple:

1. Relevance to your page and audience.
2. Organic traffic that is stable or growing over at least twelve months.
3. Recent posts indexed and ranking for something.
4. Reasonable outbound links: a few per post, not a dozen sponsors.
5. Authority scores, as a tiebreaker between otherwise equal sites.

If you want a done-for-you option, my guest posts on high DA blogs are vetted against this list before I offer them. For a printable list of on-site checks you can run on your own website too, grab the free SEO audit checklist.

What does vetting a guest post site look like in practice?

This is the pattern I see again and again. The lower score with real relevance beats the higher score with no editorial standards. If you are new to these terms, the SEO glossary explains DA, DR, dofollow and nofollow in plain language.

Keep a log of every site you reject and why. After a few months you will spot the same networks reappearing under new names, and you will vet new offers much faster. That habit alone has saved my clients from many poor placements.
