One of my websites, KeywordX.co.uk, is ranking number one in Google for the phrase Keyword X. Currently, the site is ranking on page two for Keyword Y. This phrase also has good search volume, so I've just bought KeywordY.co.uk. I've now set up KeywordY.co.uk as a 301 redirect to KeywordX.co.uk. The main site is already optimised for the phrase Keyword Y. Am I correct in thinking that if I build links to KeywordY.co.uk with the anchor text Keyword Y it will assist in boosting me up the rankings with the domain KeywordX.co.uk for that phrase, or will I be wasting my time? Thanks!
