I didn’t know this until today, so please bear with me if it’s old hat for you…
If you publish a post on your blog that runs wordpress and later decide to change the url, wordpress has an inbuilt redirect for your readers.
Let me explain…
I recently did a post that I titled 20 Great Plugins Compatible with WordPress 2.9.2. A few days later, WordPress came out with WordPress 3.0. After testing everything, the post was still relevant, but it had the old version number on it. In the old days of WordPress, it was a huge hassle using redirect plugins, etc to get the old permalink to point to the new one. I already had several links to the post and didn’t want to cause broken links or people not being able to reach the page, but I also didn’t want to be referring to an old version of WordPress so soon after a major update came out.
Aparently, since WordPress 2.1, the wordpress core automatically has a redirect function if you change your permalink! It’s as easy as just hitting the edit button, changing it up and presto! All done.
Now if someone visits the old url, which was https://seoperth.net.au/wordpress-plugins-2-9-2/ they get redirected to the new one, which is https://seoperth.net.au/wordpress-plugins-3/
No more need for me to sweat over it lol.
