How can I index keywords in Yahoo? I've do promotion, link building, joining in forum with sig and a lot more, but still the keywords in not yet index and rank.
you need to advance your opponent! I mean there's alot of competitors dreaming to be on top with those keywords that's why it takes alot of time. just continue writing about your site. and continue your link building.
I think you need to create site contents using your targeted keywords. Use your targeted keywords as anchor text.
I would focus on getting more quality links in order to get indexed in Yahoo. Target sites that are relevant to your keywords. Some directory submissions jumpstart this. In order to get ranked for multiple keywords, if their not related is to dedicate a new page to each keyword on your site.
