In the last few months, both Yahoo and Google have publicly stated that they no longer support the keyword meta tag. Bing has never used it. What impact does this have on your website and search engine rankings?
Search engines have gotten a lot smarter over the last few years, and they’re now indexing sites by keywords located within the content. While all three still use the title and description meta tags, they’re also looking through what’s actually written on your pages to help determine how your page ranks. Sites with a density of particular keywords within their written content will rank higher than ones just using those keywords in the meta tags.
