How to evaluate a guest post site before you buy

Buying a guest post is buying a placement on someone else's website. The link is only as useful as the site it sits on, so a few minutes of checking before you order saves money and protects your own domain.

Start with relevance, not with the highest number

A link from a site that covers your topic sends a clearer signal than a link from a stronger site that has nothing to do with you. Before you look at any metric, open the site and read two or three recent articles. Ask yourself whether your article would look natural there, and whether the site's readers are people who could become your customers.

Read authority metrics as ranges

Ahrefs Domain Rating (DR) and Semrush Authority Score (AS) estimate how strong a site's backlink profile is. They are useful for comparing sites, but they are calculated from each tool's own crawl and can move from month to month. Treat them as ranges rather than exact values:

• Compare several sites in the same niche instead of chasing a single score.
• Check when the metric was last updated. Old numbers can hide a recent drop.
• Look at both tools. A large gap between DR and AS is a reason to look closer.

Check that the traffic is real

Organic traffic estimates from Ahrefs and Semrush are modelled from keyword rankings. They are a good sign of whether a site ranks at all, but they are still estimates. Where a publisher has connected Google Analytics and Search Console, you can see measured users, clicks and impressions instead. Prefer measured data when it is available, and look at the trend: a steady or growing line is worth more than a single high month.

Look for spam signals

Some sites exist mainly to sell links. They often share a few patterns:

• Almost every recent article contains outbound commercial links.
• Topics jump between unrelated niches from one post to the next.
• Traffic is falling while the number of sponsored posts is rising.
• The site has a high spam score or very few referring domains for its traffic.

None of these alone proves a site is bad, but two or three together are a warning.

Read the publishing rules

Every listing should state the link type you will get (dofollow, sponsored or nofollow), whether posts are labelled as sponsored, how many outbound links an article may contain, and the turnaround time. These terms decide what you are actually buying. On our marketplace they are frozen into the order when you pay, so the publisher cannot change them afterwards.

Look at sample posts

Sample posts show how your article will be presented: where the link appears, whether the post is linked from the homepage or buried in an archive, and whether the formatting is clean. If a publisher cannot show recent examples, ask why.

A short checklist

• The site covers your topic and its readers match your audience.
• DR and AS are in a sensible range for your budget and recently updated.
• Traffic is stable or growing, ideally confirmed through Google data.
• Few spam signals.
• Link type, labelling and turnaround are clearly stated.
• Recent sample posts look like content you would be happy to be next to.

When a site passes these checks, the price becomes the last question rather than the first.
