I answered a question about metadata on a list, and I thought I'd post my answer in an abbreviated form:Yes, it is still important. ;-D
- Focus on the most relevant terms for a website. At various times, depending on their algorithms, some search engines have truncated keywords at a certain limit 25 words, even 250 characters. Any other that = seo spam So, choose keywords very very carefully and weight the most important ones at the beginning of the keywords list ;-)
- Use all of the metadata FIELDS that you can.
