Guys tell me,
There is a catalog of goods. For example wallpapers. 500 models have an absolutely identical description and characteristics differ only in the article and in the drawing. I wrote to this collection a unique text of 2600 characters. If this description is used on each card of goods with a difference only in the name of the model, will it be good or bad for me (the site)?
If the text is already unique, I would place it on one page. On the one, that I will promote. By duplicating 2600 characters of text 500 times for different goods will not be bad, but it will not benefit either.
The only benefit is that in order that the buyer should understand what the goods are in front of them. But from SEO point of view, something needs to be done with this text or there is no need? Because there are more than 2000 items of different collections and filters.
For buyers - you can. It will be considered normal. And for SEO it will be rather useless, but not harmful.
For buyers, you can print this text via JavaScript.
<Noindex> 2600 </ noindex> or you can try to hide it in js but will need to do this perfectly.
Hmm .. generally weird. Do the search engines do not understand that this is an online store and the characteristics of the goods can be exactly the same as the description ... it's like an iPhone 7 black and an iPhone 7 red! The description is the same !!!! For example ... It is really not possible to write a unique description for all 500 cards .... somehow I don't feel it is feasible ...
Therefore, do not write it - just make a table of characteristics.
