The more links posted in the blog and on sites the more prestige on google searches because of the clicks readers use. Invite your readers to click on your links, not on google ads, unless the ad is yours, remember google gets the money. You get prestige by reader clicks. So what if you have an audience of 5 or 20 people on a blog, no worry, web surfers come, observe, read, share, and slide on through. Your audience clicks matter for your performance on databases, even if having many sites with modest audience interviews will still reach many people. Check the analytics of each blog post show how many viewers looked at the post. Your newsletters (I use MailChimp.) show the clicks you have and on what links the reader clicked.
I heard maybe 8 years ago the information about linking from the networking genius who programed hyperlinking, he is a billionaire. We can surf the vast net to see what his innovation offers for us.
I also put author blogs, performances, and books with links in my newsletter, EVENTING…; the more places a book or blog is posted the better for expanding different audiences and stretching hyperlink connections.
