As far as web platforms for SEO go, WordPress is probably one of the best CMS systems to use if you want SEO tools. Plugins like Yoast are almost the standard to be installed across every site. With this being said, an off-site WordPress SEO scanner like this can be very useful for finding SEO errors that a plugin at the post level is not able to locate.
How To Use – WordPress SEO Scanner
To use this tool, enter the URL from your blog and provide the target keyword. You can use the keyword you provided for Yoast or you can use any other variations. There are no usage limits so you can run this multiple times. Click submit and the scan will make a request to your web page and run the scans.
The report at the end will show you all of the successful checks and the failed checks. You should be able to resolve everything the tool is suggesting without needing to jump into the code. Using the media library, you will be able to sort out any image problems. The admin area will let you modify the post content. There should be plugins than to resolve anything else that is not working correctly.
When it comes to performance, WordPress has some incredibly powerful plugins for this. If you have a dedicated server, it would be in your best interest to use Redis if you want to ensure maximum performance.
