Impact of CMS choice on rankings?

Question

CMS

Hello!
We have a question in the studio that we would like to get an answer to, and just hear your opinion based on experience. Does the choice of content management system affect the ranking of the site by search engines? In particular, Yandex.
There is an opinion that sites made on free CMS are worse in terms of ranking compared to commercial ones: Wordpress often makes satellites and quick sites, and Bitrix (for example) usually makes more serious sites, since you will have to invest at least in purchase of a license.
Is there any difference? Interested now only in the current conditions of Runet.

Answer 1

what I saw on Bitrix and on UNO was not seen by any WordPress in the worst nightmare!
look at Google's official mana for promotion, there are only objective factors: cleanliness of layout, speed of work and quality of updating the resource, otherwise do it at least on the brainfak.

Answer 2

First time I hear this. Even assuming it's true...how does a search engine determine a site's engine?

Answer 3

There is an opinion that some CMS with some themes (whether purchased, custom, self-written or free of both) generate such dirty code that the search engine cannot figure it out :) themes - without significant visual changes but with a significant change in the quality of the layout

Answer 4

The main thing for Yandex, most likely, is content, not CMS.

Answer 5

What is important for the PS (including Yandex):
1) Valid code (i.e. no gross errors, clear structure, no traces of “bad” optimization - cloaking, “dotted” links and other twists and turns);
2) The uniqueness of the content, the degree of its "re-optimization";
This is first of all.
My experience tells me that it doesn't matter which cms was taken as a basis. It is important what you do next with your site - whether you will increase trust, periodically write unique. content, help PS index and explore your site (xml sitemap, PS directories, adding to the webmaster panel, properly configuring the server to send the correct headers, etc.)
Tops have blogs on Wordpress, on Drupal ... in one alongside commercial CMS.
BUT it is natural that any free CMS will have to be “finished”. At least plug-ins for speeding up and optimizing work with the database)
By the way, buying a commercial system is not at all a guarantee that the code will be super good and correct.
+ Each project has its own specifics. A blog with 250 uniques a day doesn't have to worry about it.
But the online store should think about the speed of loading its pages, I think there is no need to explain why)
