1. When Google finds out that people are leaving your site without visiting other pages (high bounce rate), it will give your site a negative point.
2. When Google finds out that people are leaving your site almost immediately after your site is loaded - another negative point.
3. When Google finds out that there are too many irrelevant links pointing to your site - another negative point.
4. When Google finds out that your content has a lot of similar copies online - another negative point.
Google loves your site if your reader loves your site. Google is like human. Its just following your visitors. So, if you want Google to love your site, create content that your visitors love to read, make them stay on your site, and even visiting your other pages..... That's how simple but effective way on how to get Google's respect. It's not about thousands of backlinks delivered by spam software.
