I don't know how to beginning on the niche site

Before you even think about building a niche site, you need to do research. You first need to decide what niche market you are going to go into (dating, weight loss, video games, make money, lean guitar....) The niche you are in is what determines what kinds of products you will be promoting and stuff. Once you figure out what niche you want to work in, it's a matter of finding products to promote, doing keyword research, and just getting to know the people in your niche.

Once you do all this, you decide on a domain name. I recommend using something general in nature that reflects the niche market you're in. This way, you can promote lots of different products on it. Then, you get hosting (where the content for your site is actually stored. Then, you need to write content for your site (or outsource it), learn how to get traffic, and repeat the process. Oh, you should also build a list.

It seems like a lot, but it's really not. You just have to get the hang of it. Once you do, it will be like second nature. On the up side, now is a great time to get started because the latter months of the year are most profitable for marketers, due to the holidays and what not. There will be tons of opportunities to make money.

Good luck,

1. Choose a CMS - Wordpress is really all you need - there are are systems such as Joomla or Blogspot, but Wordpress is great for beginner.

2. Choose a theme for your Wordpress site - If you are on a budget, you can download a free theme and upload it to your site. It can be done either via an FTP client such as Filezilla or you can upload the zip file via the Wordpress interface.

Here is a huge directory of free Wordpress themes: WordPress › Free WordPress Themes

And here's a Youtube video tutorial on how to upload your theme:
3. Create content for your site and upload it. Do some reading on on-page SEO, if you're planning on getting SEO traffic from the search engines.

4. Monetize your site - you can use CPA offers, AdSense, Amazon, Clickbank, PPC advertising - there are many options.

5. Get traffic - Again, if you're doing SEO, you need to have your site properly SEO optimised. You will also need backlinks.

If you want to get traffic in a different way, consider the following:

PPC
PPV
Media Buying
Forum Marketing
Video Marketing
Blog Commenting
Guest Posting

Keyword research is the first step you need to worry about. Decide how you want to monetize and select a good KW according to that. In Adsense for example, you would search for a KW with a nice volume of monthly searches, high CPC, high Adwords competition, etc.

As already mentioned by some of the members.
The first thing you need to do is find your niche in which you are interested.
Then find an appropriate keyword related to your niche.
Checkout the competition for that keyword on google and also on google keyword to select an appropriate keyword for your niche.
Start building your membership website.

I am also with the same problem.
Thanks bro for your post.
