Hello,
I've read conflicting opinions regarding the use of meta keywords. I know Matt Cutts stated a few years ago that Google does not use them as a ranking signal but many still use them.
This raises a few questions:
1. Is there any reason to still use meta keywords?
2. Isn't it just a way to let your competitors know what you're optimizing for?
3. How do other search engines treat meta keywords?
Thanks!
