I've done some reading on SEO and I had a site on Page 1, 2nd pos for months. Making so so money via Amazon. I read somewhere that having Google Analytics on my niche site would be detrimental to my position as Google would then have insight into my website. So I removed it a few days ago. I come back today and see I'm not even in the top 100. WTH? I've not changed anything else on my site. Any thoughts?
