Here's my situation. The other day I had a ranking performed on my site and it showed only 58 indexed pages which surprised me because I have over 250 posts since 2012. But then it got me thinking since I only started using the SEO Yoast plugin for the past six months, maybe I should go back to my old posts and input a focus keyword, meta description, etc and update all those pages. I still have 150+ posts/articles that are still showing the red SEO circle beside them since each does not have a meta description or focus keyword.
Therefore, this past week I have been going back and re-editing each post (oldest first) for keyword, <h1,2,3> tags, image alt tags, title, etc. Once updated I take that link and send to the 5 social media avenues I actively use: Twitter, Facebook, Google, Pinterest, and WeHeartIt.
My question is, since I'm taking the time editing each post (about 45 mins each), is there anything else I should do while I'm tinkering with each of these posts? Or anything else I might be overlooking? I would hate to have to go back and reopen them all just to insert or edit something else. I already have a newsletter signup area below each post, a picture/bio, and links to other related posts.
Also, I was thinking about increasing my social media connections and start using others and I've read here about some services that automate this for you. My thinking was instead of just 5 SM links per post (what I now get) why not use a service like onlywire or social monkee and get 50+ links per post. Any thoughts, comments, suggestions?
