need of black hat seo

I'm new to this SEO can you please help me to know in detail about SEO

Thats not how it works.

Now that you have signed up for bhw you have access to hundreds of great threads.
Go read about BH and WH methods yourself, no one will spoon feed you.

You don't necessarily need to learn all about SEO from here (BHW) if you have zero knowledge about that. There are awesome articles and tutorials all over the web. Start researching and try to implement them on your projects to see what brings you the results.
