Generally, a banal question, which, probably, has already been answered more than once on this forum (still, I need the most recent data).
What are the most popular CMS? And what are the benefits of each? I know that there is a sea of information on the Net. I need real experience. Not rewrite rewrite rewrite, but the opinion of real users of different CMS.
How are things going with the admin panel, how is it with the SEO setting, how is it with indexing, with the design. For instance, once I worked with CMS Joomla. I remember that this CMS could not change the favicon that is displayed in SEs search. These are the interesting details.
For me, the main advantages are flexibility and accessibility.
Flexibility is also divided into two parts. WordPress is fine for those who don't know anything. WordPress is good for those who know a lot of things.
Almost always, what you need can be done through the settings or a plugin, or you can mess around in the code.
Availability. All documentation is available, plugins are available (there are free analogs of plugins for everything) and specialists are available who will help if necessary.
In order to write any kind of CMS knowledge, you need a lot. As a result, it will take at least a couple of months to write a website of a couple of pages.
To write a couple of pages on WP, from scratch, it will take a maximum of half an hour.
In fact, there are quite a large number of content management systems.
There are very popular all over the world, but there are also those who write for a specific site or a series of sites. There are CMS that are created and maintained by dozens and even hundreds of developers, but there are those that were created by a single developer.
Joomla. It is also a very popular CMS, although it is very much inferior to WordPress in terms of the number of projects.
It is suitable for different types of sites, also has ready-made templates and plugins for different occasions, but in smaller quantities. In terms of complexity, this CMS is more difficult to learn than WordPress. The same situation is in terms of usability.
Moguta. A highly specialized engine of domestic production, designed for the creation of online stores. It does not require programming skills and has a fairly simple "admin panel". The main disadvantage of this system is that the bulk of templates and plugins are paid, as is the engine itself.
Drupal. CMS, which is more powerful in its performance than those described above. This engine is often used for highly loaded sites with high traffic and which operate with large amounts of data. A fairly complex engine that is suitable for more experienced web specialists and is very difficult for beginners. News portals or heavy corporate websites are usually made on it.
It has its own database of templates and its own plugins, but many of them are paid. Usually sites on it require more powerful hosting than sites on WordPress and Joomla.
As for the most popular CMS for forums, for me it is SMF (Simple Machines Forum (https://simplemachines.org/)).
I have been using this system on many of my sites, including the current one (dnray.com), for over 10 years now.
Despite the fact that it is free, the operation of the engine is stable, and on the support forum you can always find the answer to any question about the engine, or ask your own.
For me CMS Joomla remains the most convenient. Favicon issues are now resolved. A large number of ready-made solutions, it is possible to work with the source code. There is some inconvenience. It is more complex than WordPress. But the possibilities for solving various problems are much greater, for my opinion.
My choice is Joomla.
From experience, I can say that most of the orders are for CMS Wordpress. Although I don't really like her myself, but it looks like the whole world is writing on her.
