I have a website that's consistently on top of page 2. I have a blog with about 5 unique blog posts I've written.
Now I've re-built my site a couple times, switching back and forth between a complete Wordpress site and a Wordpress-only-for-blog site. Each time I've switched, I've had to delete all Wordpress files and re-create and re-post my blog posts. That means copy/paste everything into "new" posts.
Once my newest more recent site was up I moved up on Google to the very top of page 2 and stayed there for a couple days. Today, I'm nowhere to be found (maybe page 14 or so). The only possible explanation I've come to is that Google "thinks" I'm creating multiple pages on my site with the same large amounts of content each time. The reason is because the directories change each time I change my site over (website.com/blog to website.com and vise-versa).
The same thing happened when I moved from a Wordpress site to a self-built site previously - I skyrocketed on Google for days, then instantly plummeted.
My question is... Now what? Do I remove my blog posts and start over? Or wait until Google "realizes" it's not duplicate content...? If that even happens...
Or should I cut my losses and start fresh with a new domain?
Or could it be something else completely? I can't think of anything else - although I'm not SEO pro.
