Hi Anil
I wanna to know that which method is more important to Google to rank first on its page one-page SEO or off page SEO to making thousand of backlink.
Even doing minimal onsite stuff Anil I saw a difference in search traffic. These tools can help you get your SEO game down pat, big time. Google just wants some basic signals from your blog to know what it does and how it benefits people. From there, you can do some smart offsite stuff too – guest posting, etc – and sweet search traffic will find your blog. Always does if you follow the rules.
