Hey guys /gals I have a question please.  I have a computer repair business that does extremely well in search and is on the front page of google for anything computer repair related. However, I am currently re-branding my company and have completely redesigned every aspect of the UI and the SEO Site structure as well as the fact that I have completely written vastly different content and different title tag lines and meta descriptions for each page. So basically when doing a migration we know that we want to keep our content, titles, headlines and meta descriptions the same as to not lose our page rank. Seeing that I have completely went against the grain in all directions on a much needed company re-branding and everything is completely different from the old site is it even worthwhile 301 redirecting my old urls to the new ones that would (best) correspond with the new? In the plainest English, would I do better at Ranking the New Website QUICKER without doing 301 redirects from the OLD to the NEW? In an EXTREME instance like what I have done, would the Domain Migration IMPEDED me ranking the new site seeing how nothing is the same? I have build a Rock solid SILO Site Architecture on the New site which is WordPress using the Thesis Framework and the old domain is built on JOOMLA 1.5 Thank fellas Marshall
