Currently there are many SEO plugins for WordPress in the market. But these plugins often have too many options and are very complicated for ordinary users. Access to their configuration section, you will easily get lost in a maze of explanations and options that you sometimes don’t understand. Besides, there are ads!
So how can an ordinary user use an SEO plugin?
SEO should be an integrated part of WordPress, where users don’t need or need very little effort to configure for SEO. The main reason is that not everyone understands the terms of SEO and how to configure them optimally.
So, we made Slim SEO.
Slim SEO is a full-featured SEO plugin, that’s done right! It provides a complete SEO solution for WordPress where the c…
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.

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!
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
– Etc
Great job!
Don’t need all the bloat of other seo plugins, just a sitemap and tag editor, excellent. Some of the other ‘simple’ sitemap generators don’t have options to disregard certain posts and pages, which is not helpful when you’re trying to hide your logged in pages. Simple SEO makes it simple by allowing you to go to the page and tick a box, great, refreshed sitemap already generated and the pages I wanted to exclude – gone. Brilliant, Thanks.
I tried it for the first time. It’s simple and straightforward. I liked it. The only downside, in my opinion, is that we need to be able to replace breadcrumbs “home” with the word in our language.
If it supports Turkish, I can use it on more sites.
