Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

what are you trying to achieve? and what language?
You basically have to put commas and quotes around each keyword. A keyword, though, can contain spaces.

Example: "expert exchange","knowledge","do it yourself", etc etc....
I think it's HTML and meta-tags keywords. Am I right?

Sorry for my incomplete info.

It is a ecommerce website, i use a mysql DB, the language for that is php.
I have a several files, like header.php and metatags that i can edit in my back office and attach metatags in each category/products.

What i want to achieve is that my keywords is easily recognized in search engines and people find my products. I have the website in 4 languages, so i put keywords in the 4 languages.

Because i see in lot of websites different ways to put keywords, i want to know what is the correct way.
