This is how I do it for my blog. I am not suggesting this is how you should handle it for your blog or website. I use WordPress so I don’t know how Blogger/BlogSpot or other blog platforms handle the issue.
When I add links to a post, or include links in a quote, I set them to open in a new window/tab. Other bloggers and websites go with opening in the same window/tab. A small group go with a mix where some links open in a new tab, but other links redirect to the link. This includes many of the major genealogy websites that go this route where some links open in a new window/tab and others open in the same window/tab.
If you ever notice one of my post links not opening in a new window/tab, please let me know. I do my best to have them all open in a new window/tab. Occasionally, one slips through where I forgot to click the Open link in a new window/tab checkbox.
When I am visiting another blog or website on my laptop and it has one or more links, I always right-click on the link if it looks like something I want to check out and open it in a new tab. Once I am done reading the link, I close the new tab. I can’t easily do that on my phone so I click on the link. If it opens in a new tab, I close the tab once I am done reading it. If it redirects me from the site I was on, I either use the Back key or close the tab, depending on if I was done with the original site.
