Our business website forums running since 2 year
now we have a problem with the domain name, person who registered the domain had internal disputes and started his own business on the same domain name. www.olddomain.com
The issue only resides with the domain name, all other data for site database, customers, server provider are registered with us. Since we did not had any legal agreement for the domain, we cannot do anything for old domain

At last, we have to shift to a new domin www.newdomain.com
our old domain has a pageranking 7.0 and we get around 25000 visits daily from search engines, there are more then 15000 registered users.

If we start with a new domain name will this effect our business as we target our customers only from forums.
How long it should take for the new domain to get traffic like before as we had more then 25000 uniques daily and what would be the best way to get the things started immediately ?

You've got to get word out of your new URL. Have you thought of submitting a press release? If the new URL is significantly different, you might be able to use that route. Talk a little bit about your company, tell people the new URL and the old one, but you might want to look into a reason for changing the company URL...that doesn't say, a former employee / associate took our old domain name.

This, along with:
* register the new domain / domain change with every search engine
* post (don't spam!) in forums and list your new domain (as a link) with the old domain (as text) in your .sig, if this doesn't break that forum's rules

...and make sure that this time around, the company has the legal lock on the domain name.

I don't know how long it will take until you're able to get all that redirected traffic - but if you get the word spread widely enough, this will help get some of it back.

thank you for feedback lesli,
the old domain has now been legally registered, so if we use the name of old url we will be doing legally wrong.

We will try our best to remove the old url from all the places we have visted and remove the same from every site we have done, it took us nearly 2 years to make a status but a complete domain change will affect us

we are only concerned about the total time it should take to get all our old traffic back

I am no expert .... but if you know all the forums you went to and if your domain name was in a signature you set up that is attached to all your posts ... and if those forums operate like most of the ones I am on ... when you change the domain name in your signature it will automatically change on every post you ever entered in all those forums.

Lots of "if's" ... but worth checking out maybe
Good luck
Peter

we are more concerned on the traffic build up time, we are currently very depressed due to the big loss of traffic which served main keypoint for our business.
Is there any estimate you can lay down for same ? this should give us an idea for the amount of work we will have to put on the new domain name.

Old Domain rank/traffic is not associated with the domain name at all.
rank is based due to the enormeous no. of link exchanges done by us and we can modify these links in few weeks to point to our new domain adress.
Our entire content is intact with our systems person under our custody , the only dilemma left is our 2 years of work.

Do you have any of the customer data? If so, you should e-mail the customers of your forum and inform them about the change. You should also post in every forum possible that this change has taken place or you should get a completely new domain name. When (or if) you register a new domain name, make sure that you go to the control panel and lock that domain. Check the status at a website like http://www.whois.sc/ (Whois Source). Make sure that the status is set to "REGISTRAR-LOCK". This will prevent anyone from changing the ownership of the domain. If a domain name transfer were to take place, then you would need to remove the lock for it to occur. Personally, I'd purchase a new domain name and get the word out. It sounds like you have had a great experience with your old domain name. I'm sure you could make a new domain name have the same effect. Although this is probably what you didn't want to hear, I think it's the best move.

IMO, to get fast results, you need that domain back. Did you try to buy it from the current owner? Otherwise it seems to me that it can very well take half a year or more to get back to where you were after starting anew.

Dan, that's the only downside with getting a new domain name--time. The time it takes to get the site to the point that the previous site was. I have a feeling the new owner won't sell it or will charge an exorbitant price for it. If he didn't want something out of it, why did he grab it?

We can expect him to want to cash in, but it might be worth it for John1968. There's no guarantee he can create such another succesful website again rapidly. The growing process could very well take another two years.

thank you for all your feedback, but we still have not got answer to main technical problem

how should this take for us to get our entire domain traffic back ?

I believe we have answered this to the best of our ability. No one knows for certain how long it will take for you to receive most of your traffic back unless you try it out. I would say 1-2 years would be a safe bet.

thank you for your replies

Have you tried to get your old domain name back?

i have tried but the old domain owner is not ready to change the ownership

Anyone is ready to change ownership if the right price is offered.
