Definition:
An inbound link is a hyperlink transiting domains. Links are inbound from the perspective of the link target, and conversely, outbound from the perspective of the originator. Inbound links were originally important (prior to the emergence of search engines) as a primary means of web navigation; today their significance lies in search engine optimization (SEO). Many search engines rank pages based on inbound links. A company attempts to place as many inbound links as possible to their site regardless of the context of the originating site.
Why do we need inbound links?
Google came on the scene; link popularity (linkpop) was being used by one or two search engines as part of their algorithm when determining the rankings for any given searchterm. Then when Google arrived with their link-based PageRank, link popularity took off and became an absolute essential ingredient in achieving top rankings.
The idea behind linkpop is that the more pages that link to a page, the more important the page is and it, therefore, deserves a higher ranking than it would otherwise have.
Some engines simply counted the number of links coming into a page (inbound links), but Google took the idea a step further. Each inbound link comes from a page which itself has inbound links. The more inbound links on the linking page, the more important that page is and, therefore, the more important the link to our page is. So Google gives more weight to inbound links from important pages that it does to inbound links from lesser pages. They call the idea "PageRank".
Way to get inbound links:
There are a number of ways. Some of them are:-
Directories
Directories usually provide one-way links to websites, although some require a reciprocal link. Personally, I have no time for those that require reciprocal links, because they aren't really trying to be useful directories. Submitting to directories is time-consuming and boring, but there are a number of cheap directory submitting services that do a very good job. There are several of them in this forum thread.
Forums
Join forums and place links to your site(s) in your signature line. Use your main search terms as the link text. But before spending time writing lots of posts with your signature line in each post, make sure that the forum is spider able by checking the robots.txt file, and make sure that non-members don't have session IDs in the URLs. Also make sure that links in signature lines are not hidden from.
Link exchange centers
Find a join free link exchange center like LinkPartners.com. There you can find a categorized directory of websites that also want to exchange links. Link farms, such as LinksToYou.com, sound excellent for building up linkpop and PageRank, but search engines (Google in particular) disapprove of them as blatant attempts to manipulate the rankings and they will penalize sites that use them. Once a site has been penalized, it is very difficult to get the penalty lifted, so avoid all link farms.
Email requests
- Search on Google for your main searchterms and find the websites that are competing with you. Then find which sites link to them by searching. Email them and ask for a link exchange.
- Search on Google for websites that are related to your site's topic, but not direct competitors, and ask them for a link exchange.
Finally, there are even links for sale by public auction, such as the one at LinkAdage Auctions.
Link-types:
Inbound links are following types:-
- they add linkpop and PageRank to the site,
- they send traffic to the site,
- for linkpop, either text or graphic links are fine,
- for traffic, text links are known to be more effective than graphic links,
- to improve the page's rankings, get links from anywhere - the higher the Page Rank of the linking page, the better and, whenever possible, make sure that the link text is one of your main search terms.
Summary
Inbound links are important and essential for achieving top rankings. Many websites that are approached to top rankings, it is essential to take the time and get many inbound links.
