Hello,


you said right that link building play very important role in seo and in promotion of website.Building links through reciprocal link exchanges is a simple yet very powerful website promotional tool.
If done correctly, increasing your linkage will:
1. Increase your traffic significantly.
2. Improve your visibility in the search engines.
3. Provide an added resource to your website.
4. Save you a lot of advertising money.
5. Save you time.
Before you start, you need to know that the largest drawback with building one's link popularity properly is TIME. It takes time to:
• Find the websites to link with
• Make the link requests
• Wait on those link requests
• Process, organize, and manage the links
• Have the search engines find or "spider" your link partners
• Check to see if your links are still on your partner's websites

thanks!!

Clicking a link from a trusted source is one of the most popular ways for people to find a new website. If a user is on a website they trust, they are likely to follow links that it recommends - or at the least, users will follow links that make the destination site appear to provide some valuable information.

The main benefit of link building is to increase traffic
bring your sites first by search engine

There are two good reasons why you go for link building:

1. It puts you in search engines. Unless you’re found in Google, Yahoo, and MSN, your online business is non-existent. It also doesn’t help if you’re found a lot of pages away in search results. Your main goal should be at least among the top 10 on the targeted keywords you’re using. Research says that online users click the first website in the list, believing it’s the most relevant answer to their query.

2. You get a lot of traffic. Traffic is important as majority of the prospects come from there. You will further increase traffic if your website is linked in other webpages.

The main benefit of link building is it increase your back links and traffic too.......

Link building is the easiest method to get your website ranked in SE. But it needs dedication and time..

Thanks for your nice input.
I think backlinks from niche relative sources should be useful but the backlinks from irrelevant sources would be useful, too.
And, usually, the main purpose of building backlinks is to boost your SERP.
