Are Meta Keywords Obsolete?
Yahoo announced at the SMX East conference yesterday that they were no longer using meta keywords. In the report Yahoo stated that they had announced this earlier in the year - but apparently no one outside Yahoo got the memo. While none of the major engines now support meta keywords, I still recommend using topic and category specific keywords in all your pages. There are a lot of spiders crawling the web that still use this information to categorize your content and can result in back-links to your site.
