It's good to have a primary subject/theme for a site which can help search engines as well as users better understand what they will find on the site, but a single keyword is usually too narrow a focus, (one exception are micro niche sites that may use an exact keyword matching domain name, very effective at one time adjustments are probably being made to lower to the effect of such domain names,)

Commonly webmasters might research and compile a list of around 50 target keywords that they would like to rank for, often larger competing sites prevent your from effectively ranking for the ideal keyword like "Weight Loss", ranking for 'long tail' keywords like "Natural vegetarian weight loss diets" will have less competition, indicated in part by the number of results Google shows for a search, it's a common practice to feature a keyword from your shopping list in the meta title, header and body text of a page.

I'm having an issue with the Focus Keyword on WordPress SEO plugin - sometimes works, sometimes doesnt.

I'm admin and I can see that it works (it gets green if I have the kw in the right place) but then a user with only author rights sees it all RED.

This is a big problem for me, I'm trying to make a point and instead look like a newbie without an answer...

Did anyone encounter this problem? How can I fix it?

Thank you,

Focus keyword should be only one.. So that Search Engine better understands for which keyword your page should be displayed in search.. It will be better to use some synonyms of focus keyword in the article body.

It should be multiple KW so that it does not seems like that we are promoting these keyword by force it which is wrong and google can put our site to spamming

I am creating a website on wordpress and trying to figure out SEO.

Focus KW - In this section do I entire only the main Keyword Phrase? Or do I insert multiple important keyword phrases? Also if I insert multiple keywords does it matter if I use a comma or semicolon in between each phrase?

Thank you!
