I've been reading about meta tags, and many websites it's no longer important for Google and other searchers to use the 'keywords' meta, causing some doubt of use in the project I'm developing.
After all, is meta keywords still necessary? Still have some weight for search engines?
Google does not use the meta tag keywords to process the ranking of sites that will appear in a search. In the link below you can check which meta tags the google robot uses to index the sites.
The Yahoo search engine uses this meta tag, but the words contained in it have less relevance than words from other places, such as those contained within the body, title, description, or anchor tags.
Bing uses the same idea as Yahoo: meta tags are a sign, but with very little relevance.
If you have search engines in mind, using the meta tag keyword will not help. This tag has already become history:)
