It depends on where, how and why you use the article.
You can promote your e-commerce product in 100 words.
You can describe all details in 300 words. You can type 500 words.
Purchasing, shipping process, order process, delivery, unpacking, product usage, what to do, how to use it, error situations, what to do in case of corruption and many other information. It can be described in an article of 1800 words.
Which is more effective?
It depends exactly on what you want to do. A good article is written in 100 words. You can describe your business in 100 words.
In this case, how much will your site benefit?
Exactly how long the reader is on the site and what he expects from the site. When navigating between different or similar products, it takes no more than 1 minute to read the product. Lead's lead time is 1 minute.
But here we can find answers to my question by addressing different sites. 200 words while developing your own business. In Medium, the user writes 2000 words that you cannot type with 200 words.
Therefore the medium site is one of the largest sites in the world. The only effect is long articles and meets the expectations of the reader.
As a result; You should give priority to what the reader wants. Don't think that SEO is focused. Write this knowing exactly what the customer wants. This will improve your quality.
