I will make a website with 5 webpages. the list of questions:
1. How many keywords should I include to web content article per webpage?
2. How many times should the keywords appear in the web ...
So called SEO experts recommend around 5-12 keywords in a 250 word article. But personally I think that's too many. I prefer not more than 3 keywords in a 250 word article, but it's just me.
