When adding links to websites should you force links in to a new window or leave the visitor to decide? If you do force the link in to a new window should you make it clear that the link will open a new window, either by adding a note at the end of the link or using the title tag or a cover all notice somewhere on the page that says all links open in new windows?
Forcing the link in to a new window will mean that the visitor will still be able to see your site. If the link you have provided is interesting (the purpose of providing it should be that it is interesting should it not?) then the visitor could be several pages in to the linked site or even on a site linked from the original site and may just close the browser and forget about you. There is an argument for the handy Back button on the browser, but how many times have we clicked though a link and a couple of pages and a link then you are maybe 20 or 30 clicks away from the original site. Yes you could right click on the back button and look for the site in there or go in to your internet history, but how many novice users know about this?
You are taking the choice away from the visitor. If they want to open the link in a new window or tab there are any number of ways for them to do this.
I’m indifferent as I usually right click and open links in a new tab anyway but what are your views?
