Welcome to the Q&A Forum

I'm thinking about uploading photos to my Google+ and then embedding them in my post. Will adding photo from Google+ help me rank better.

I have blog posts on my site that don't have comments. However, I cannot find my pages in google search. Does the lack of comments on my blog posts hurt my ranking in google search?

I write short blog post between 80-100 words and I link out to other websites. However, How many external links should I have in each blog post to rank better in search?

I'm thinking about adding a sidebar on the right side of my blog post with links to other pages. Is have a sidebar with links to other pages good or bad for SEO.
