What is a 404 to 301 plug-in?
This is a plug-in that will send a person that found a page not found at to the front page of your website or whatever other page you designate. 404 is the error code for a page not found, a very frustrating experience for a person that is on the Internet and a signal that a website is improperly configured. When a website has many 404 errors google may see it as an improperly configured website that should not be rewarded with a high-ranking; in other words, if your website is returning 404 hours to people after they click on Google results, there is a good chance that you are going to lose search rank. This is why it is a good idea to set up a plug-in like this that will redirect any 404 page not found two different page of your website or some other page that you choose.
There are a number of these plug-ins. My recommendation is that you go through the plug-ins that are available on word press.org and try out the ones that seem to have the highest number of installs and highest ratings. This is not a function that road require particularly complex coding, so the odds are that whatever you download is going to work. At the same time,These plug-ins are accessing your.HT access file, which could potential he screw up a website pretty badly if done improperly. The best thing you can do is to create a back up of your website before you install any plug-in like this.
Once you have the plug-in installed and configured, you shouldn’t test it by looking for a page that you know does not exist on your website. You will know that the plug-in is functioning if it returns you to the page that you designated as the destination for any 404 responses. If you find that you ended up where you want to do, you know that you are good to go.
