So what I'd like to do is generate a meta description like this one
<meta name="description" content="[post_title]Craftsman 3 in 1 tool set. [post_content]This is a sentence or a few words from the main content body text which was entered in the post or page description of item..."/>
The meta description would take the page title and a few words or a sentence from the main post content.
Currently no meta description is being generated as I can see. Could you recommend a way to work this in. I'd like to avoid using bloated plugins etc and it is not feasible to go through each post 1 by 1 and do this manually as there are thousands of posts and pages.
