Offers a do-follow link. This is usually the case, but look carefully at the guest blogging guidelines to make sure that your bio link (or in-post links) will be “do-follow” rather than “nofollow” (as a nofollow link won’t do anything to help your blog SEO efforts). If there’s nothing stated either way in the guidelines, check out a past guest blog post, scroll to the bio, right-click on it, and select “Inspect” (in Google Chrome) to see the HTML code for that hyperlinked text snippet. If you see the word “nofollow” within the HTML description of the link, then it’s a nofollow link. If it doesn’t explicitly say the word “nofollow,” then you’re good to go.
