Using an exsisting domain for a new busines?

[fun52dig]

I have a domain name that is in use and has a domain age of 4 years.  My question is this, will taking that domain name and promoting it under a completely new business in a completely different industry with a totally different business model hurt getting this new business to rank?

The domain name is my first and last name.  I've been promoting videos that I like under this domain name.  I would now like to use the domain name to promote my local SEO services.  Will this hurt my efforts to rank with search engines since Google and others have been indexing the site for a certain industry and topic?

Thanks
Gary

I would give it a try. Having a 4 year old domain (probably registerd to your name) with existing backlinks and a natural link profile is worth a lot. The worst thing that could happen is that your exixting links will be devalued a little bit b/c they are no longer relevant for the topic.

Make sure to 301 incoming links to / or another reasonable page, thus getting the linkjiuce. If you use wordpress as cms this is pretty easy: just add this to your header.php and test if it works (with life http headers or so)

Get a local profile with google, bing etc and start from there.
