I am helping thousands of dev bloggers attain creative freedom with Hashnode. I am Sandeep Panda, ask me anything!View other answers to this thread
A few sites include a random string at the end of the URL like below:
What is the relevance of the random string in the end?
Given it has no SEO value (and infact makes the URL longer so if anything a slight negative SEO value), does it serve a usefulness in any different context?
I understand it can be turned off, but why not turned off by default?
Thanks a bunch!
Previously when there was no personal blogging angle, every post used to live on hashnode.com domain. To prevent permalink collision, we had to insert a unique identifier in the URL. It's a pretty common pattern among content sites.
Today it's turned off by default unless you choose to publish on hashnode.com (not personal blog).
