Why did my wordpress blog drop out of the search after installing a new theme?

Question

Google

there is an old blog, about 3-4 years old on wordpress on the topic of design, IT, at one time there were 130-200 visitors a day, after changing the topic it collapsed. I'm guessing - either because of this, or because of the run through 1ps, but the run was 4 months before the collapse. Now there are 3-5 visitors. What happened?

Answer 1

The very first thing that comes to mind is the wrong layout, taking into account SEO:
Now many theme developers make them very heavy, for example, recently in some theme in an uncompressed css file there were about 16,000 lines of code. And there are many such files. And jquery plugins for thousands of lines of code with all sorts of goodies. Yes, it's beautiful. But only. I really want to get kicked in the head for this.

Answer 2

Well, the most sensible idea is to open Google Analytics and Google Webmasters, and there already pick and see what and how.

Answer 3

it looks like it, especially about heavy buns and so on - the theme is beautiful, it adapts to different resolutions, unlike the previous one. And yes, there are several jQuery libraries included. I'll try another theme, simpler, or go back to the old one, rubberize it.
