I found some helpful insights on Internet about keywords…
Here is one:
“Definition – What does Keyword mean?
A keyword, in the context of search engine optimization, is a particular word or phrase that describes the contents of a Web page. Keywords are intended to act as shortcuts that sum up an entire page. Keywords form part of a Web page’s metadata and help search engines match a page to with an appropriate search query.
” What Do I Care About Keywords?
Keywords are how the search engines know what you’re all about and who they should send to your blog. What are they and why do I need to know about them? Are they really that important to me and my blog? Can’t I get by without them? I mean, it’s all about the content right? So if I just write a really cool article, people will find it, right?”
