Meta keywords

Because of abuse in the early days meta keywords are now mostly unused by search engines. For all intents and purposed Google disregards them. They are found between the head tags on a page. Include them just in case and for those other search engines which still use them.

1.No more than 50 at the very most
2.List them separated by a comma and no space
3.Start with the page’s important keywords
4.Use plurals and do not capitalise
