How many long-tail keywords should include?
In this image you can see, Meta Tiitle, Meta Descripion, and Keywords Section.
I have three question in this regards
1. How many long-tail keywords should I add this box?
2. Those all long-tail keywords should be in the content, that means, can I add any long-tail keyword relevent to the post, in this box?
3. Is this section's keywords important to rank the site?
I have doubt about such thing, when publishing the post. Please join with me to share your knowledge and experience. I highly appreciate your participation on it. Thanks so much your joining.
