Forget it
Create problems with the sitemap, even if not activated, create sitemap redirects. What can be a plugin that can not even do an automatic sitemap redirect.

Slim, not bloated, SEO simplicity.
I've used other SEO plugins, and while they all have their place, the sheer amount of bloat and unnecessary bells / whistles and challenges these plugins add is outrageous.SEO is an important element of our sites, but once set up, that's enough. Slim SEO automates a lot of the work, and yet you can tune anything you need to with ease. Their documentation is spot on as well.Efficient and comprehensive. A great plugin for a novice to even a professional.

Avoid this!
Hey there, apologies but I have to provide a negative feedback. I think this plugin and the possibly the small company behind are not worth paying for at all. I watched some SlimSEO videos and got really hyped as I wanted to get rid of distractions with SEO related activities. I was using Rankmath PRO for the last 5 years and switched to SlimSEO PRO. At first, it was just fine. I was cleaning up a lot of bloated content while utilising the SlimSEO. I was also going through the schemas. With the latest update, Schema function just broke. It basically doesn't work. watch?v=ItNGDr5H2nI It disappears when I add a new one or want to see an already existing one. I mean this could happen, and would expect developers to take immediate action as the plugin I paid for doesn't work anymore. However, this company is extremely slow and I almost feel like they ignore me. It's been already 2+ days and I shared this screen recording right away with the founder, but it wasn't even watched. Unbelievable. I think you guys have a long way to go and you shouldn't really ask for any money for premium features that you don't even want to stand up for! Today, I bought ChatGPT plus membership, went through every aspect of SlimSEO and already got a custom plugin for me website. I regret having bought SlimSEO PRO without thinking too much. This is the second time I decided to support a smaller plugin manufacturer, but again I failed with my decision. Never again!

Fantastic plugin
I did a thorough comparison of SEO plugins and Slim SEO came out on top:- Easy to use GIU- Very well documented- No hard upsell windows unlike some other SEO plugins- Extensive range of features- I think the ability to customize eg the output of schema using code is fantastic- EtcGreat job!
