Yes that right, for the sake of the user try not to open a new browser window.

When you are  creating a link you can always insert the  <target="_blank"> tag open the link in a new window.

I must say that many webmasters does this mistake when they start of with their website. The main reason is quite simple: “Everyone likes to add the target attribute so that when users click on external links they will not leave the main website but rather have a new window opened”.

However the flaw behind this choice comes from the fact that opening unrequested browser windows will not only upset the reader but often annoy them. You should leave the decision about whether to open the link on a new window entirely to the end user.

Also, don’t worry about sending your site visitor to another site, that is why there is a back button right?
