One thing you can do to make your blog search engine optimized is to enable meta description of your blogger posts and pages. This meta description will be shown below your blog post or page in search results in search engines or when you share your link in google+, facebook, and other social networks.For example when someone is searching a keyword, in google and one of your posts appears in search results, he/she definitely read the description first before he/she choose what link to visit ,that’s why making an optimized meta description could help our post to convince people to visit and read our content. See the screenshot below.
