How do you evaluate a guest post opportunity beyond DR and traffic?

How do you evaluate a guest post opportunity beyond DR and traffic? What metrics or signals have given you the best long-term ranking results? Also, what are the biggest red flags that make you immediately reject a guest posting site, even if it has strong authority metrics?

DR and traffic are a good starting point, but I don't think they tell the whole story. I usually pay more attention to whether the site is actually relevant to the niche, how often it's updated, and whether the content gets real engagement. If every article is clearly a paid guest post with random outbound links to unrelated industries, that's a red flag for me. I'd rather get a link from a smaller, well-maintained niche site than a high-DR site that looks like it's selling links to anyone. Curious to hear what others consider the most reliable quality signals.

i care more about quality than high numbers. i check if the site ranks for real keywords, has a natural posting history and doesn't accept every guest post under the sun. big red flags are obvious paid link farms, recycled ai content, spammy outbound links and pages that never get indexed. those rarely help long term.

I look at topical relevance real organic keyword rankings content quality and whether the site has a natural backlink profile Red flags include obvious link farms irrelevant niches AI spam content and a high ratio of sponsored or outbound SEO links.

I still check DR and traffic, but they are never my deciding factors I pay more attention to niche relevance whether the site ranks for its own keywords the quality of recent content and how many outbound links each article has I also look at the backlink profile to see if the site has earned genuine links rather than relying on artificial ones

The biggest red flags for me are websites that publish every niche imaginable are overloaded with sponsored posts have thin or AI-looking content or show a declining organic traffic trend Even with strong authority metrics I usually pass on those because they rarely provide long term value
