Do not open new browser windows

When creating a link you can insert the <target="_blank"> attribute to make that link open in a new browser window. I must confess that I used to do that mistake when I started blogging. The logic was quite simple: “I will add the target attribute so that when users click on external links they will not leave my website but rather have a new window opened”.
The flaw behind this reasoning comes from the fact that opening unrequested browser windows will only upset the reader. You should leave the decision about where to open the link entirely to the end user. Also, do not worry about sending visitors to another websites, there is a reason why most browsers come with a huge “Back” button!
