I have a jewellery website with a name that does not contain keywords. Say my primary keywords for this website are for example "platinum" and "jewellery". If I then get the oppertunity to buy for example platinumjewellery.blah that has been established for say 5 years and has 2000 good backlinks what impact would buying and pointing this domain at my website have? To make it clear both new and old domain name would remain pointing at the same website. Will I affect the existing domain name and SERPS? Will the new or old name get blacklisted at all - is it considered ethical?
This is an ethic but not a smart move anyway. If you are going to buy a five years established domain with keywords contained, why don't you just move the content from the old site to a new one instead. Your old site has no benefits anyway and just pointing the link from a five years established domain to your current one would be a waste. Why? 1. Since your new domain has no really content then the trust would be dropped in a soon, plus link popularity too. 2. Just sidewide link from one site pointing to your domain could not help that much as you may ever expected. One site is an old domain but just a dropped with no content in it, while another one is a low value domain name and has no trust. See?
Bad idea. I don't think you accomplish anything. If the 5 year old site ranks well and gets decent traffic, I would make it the main site and forward the other to it. If you are doing all of this only because you don't have keywords in your current site's domain name, don't bother. I can give you hundreds of examples of sites that rank #1 with no keywords in the URL.
Nothing unethical about it; just make sure whichever way you go that you use a 301 redirect so you don't have what in effect would be duplicate sites.
You would get a lot more benefits by pointing the existing domain to the new keyword rich domain via a 301 redirect. What this does is, in short, transfers all your old domain's karma to the new domain (301 is a way of telling Google that your website has permanently moved to a new location) and makes your content domain keyword rich.
Yes this is a good question I have several Domains, all with different types of content and I tried linking to my other sites where it would be relevant and make sense however google has yet to pick them up as a backlink. I forgot to mention that they are all on different hosting accounts with each one having a different domain. I thought this would be a good approach however so far this is not a good idea. I mean I am not taking a site lets say about polar bears and putting a link for a bmw site, The link are ligitimate and relevant, all of my domains have at least a pagerank of 2. Perhaps google uses the whois information and takes that into consideration the other thing is that my sites are fairly new like between 6 months to a year. I do have one that is 3 years old and the links aren't picked up from that one either. Another thing that I question is I use 1 google analytics account to manage all of my domains and see the traffic. I recently got several domains with a valid pagerank 3 and up that are over 10 years old. I don't expect much traffic to these site and will not use the analytics for this domain and see if this helps any. If anyone could shed some light on problem that would be great.
