I had lunch with a friend of a friend today, a notable investor in the Chicago community, thinking about buying some businesses. He was thinking about buying 2 businesses, and merging them into one, under one domain name. So his question to me was “do I just 301 the name that I no longer wish to use?” He obviously knew about SEO more than the average business owner. Let me paraphrase his question, and try to explain it in simpler terms.
If you ever want to move your website address from one domain to another, you need to do a few things to ensure that you do not lose your existing organic traffic. So if you are not receiving any organic traffic, this topic does not apply to you
If you are getting organic traffic, it means that Google and Yahoo have found your content, liked it, and thought it had relevant content for certain search queries. (That is why you are getting the free traffic from Google, you search for a search term, and you show up in search results). And more than likely, before or after Google liked you, some other sites might have liked your content so much that they might have linked to your pages as well.
Now, if your old site name is oldsite.com, and your new site name is newsite.com, and if you shutdown oldsite.com and move all your content to newsite.com, and turn it on, you will lose any and all traffic to your website.
Changing your website name is not an overnight process, and for it to be done properly, here is the list of steps I suggest you make:
1-Turn on your newsite.com, make sure all content is accurate and complete, all the functionality is working properly.
2-Send an email out to all your existing customers (direct users, who directly type in your domain name than search for you online) and tell them that your site name is changing. And feel free to take the next step, and give them an incentive (free something) for them to go to your new site and to register/fill out/do something on newsite.com
3-Look at your website stats (a.k.a. analytics) program and see the sites that are ending you traffic. Contact these sites, and ask them to update the links they have on their site that is linking their users to your pages. To make their life easier, I suggest you look at their site and suggest what new page of yours they should change their link to.
4-Technical part - Free to ask your technically savvy nephew to do this for you. Google has a system by which you can submit urls of your site to google. In this file, you can tell google that the url oldsite.com/blahblah.htm is not valid, and now they should replace www.oldsite.com/blahblah.com with newsite.blahblah.com. Your nephew/niece/IT person will need to use a “tag” called 301, which mean that the change is permenant, and there for the old link should not be used again.
Do not do step 4 before doing the others.
