How to increase website conversion?

Question

Conversion

There is a company website: arthata.by
Made on the prestashop engine
The company is engaged in the production of photo wallpapers, paintings from photographs, printing on glass. Everything related to printing for the interior.
The site is being completed for the second year.
Every day I think about what to improve.
Tell me in your opinion how to increase the conversion of the site?

Answer 1

Well, what about your incoming traffic? You need to look at how many people visit the site every day, what exactly brings them here. If you are doing advertising, then analyze its effectiveness and check how the requests correspond to what the user sees.
If only search, then what queries are you showing up for and how well you are progressing.
Maybe the conversion is not growing either because something is wrong on the site, but because the advertising / SEO is not very good. Or they are just few.
Next, we are already looking at what is wrong on the site itself. Here, sales funnels, bounces (on which pages, where people merge, where there may be errors), etc. will help.
If you just look at the site and say your "feelings", it's a pitchfork on the water. Everyone has their own feelings. And the eyes blur quickly.
I see that there is a lot of different information in all blocks, my eyes run wide, not all descriptions are clear to a simple person. This is at first glance.
Lots of targeted action.

Came home from the factory in the evening :). I flopped down on the sofa with a laptop and a bottle of Baltika :) . I looked at your site for a few minutes. Took a few sips of beer :). I also looked. The most primary feeling:
Very little air on the site, too much information in one heap, loaded navigation. My brain started to boil. It's starting to get nauseous. Not something to buy, but I just want to run away from the site :).
