Frequently Asked Questions
How do I know if a guest blog site is worth it?
Look at authority, real traffic signals, topical relevance and outbound link patterns. The Guest Blog Checker pulls these signals together for any domain you paste in, so you can judge a site in seconds instead of digging manually.
What spam signals does the checker look for?
It flags patterns common to link sellers, such as excessive outbound links, thin or off-topic content and sites that publish anything for a fee. These placements rarely help rankings in 2026 and can actively hurt your link profile.
Is the Guest Blog Checker free?
Yes. The Guest Blog Checker is free after creating a Brainito account. Vet every prospect on your outreach list before you pitch, and recheck sites later to make sure their quality has not slipped.
