My tip stems from selfishness and is directed at my fellow bloggers. It drives me nuts when I click on a link in a post and it takes me to the link within the same window as I was reading the blog. I wasn't done reading your post! Now if your link is really interesting and I click through a number of pages, it takes me forever to back up to your post. Here's the solution: add this
The result is the link will open in a new window or tab.
Blank Target link: My Etsy Shop
No Target link: My Etsy Shop
It will make me (and others) stay on your blog and easily be able to pick up where we left off.
