Your inclusion on my blog is not a long term guarantee of anything relating to SEO or the like. If the blog moves, closes, or changes, your post may vanish into the ether. For that reason, I recommend you make the most of it while it's there. Make a fuss about it in the week it's published, and share the news on social networks and so forth. Post answers to questions in the comment section. You're the author, so people will want you to answer their questions. Make use of it, and try to arrange similar posts on other blogs in the weeks that follow. That's what makes a blog tour.
Very best of luck,
