To exchange produce or services directly without the use of money, we can use the free web-site promotion. There are many ways to promote the web site. Each one are explain as under.

LINK EXCHANGE:-

Network where participating sites display exchange for credits which are transformed into displayed on other sites. When not given freely, link exchanges are usually exchanged in a reciprocal agreement between two sites. Whereas banners are often dynamically rotated, link is often hard-coded onto a page. There are no link exchanges as big as the major banner exchanges. However, there are some networks keen to give it a try. Link exchanges anticipation to come together the countless reach of their banner counterparts with the high response rates of text ads, plus the added benefit of multiple exposures per page. While this may sound good in theory, the same caveats about other exchanges still apply. Make sure you are getting a good value, and make doubly sure the link exchange does not detract from your site.

BUTTON EXCHANGE:-

Network where participating sites display button that exchange for credits which are converted into the displayed on other sites. Button exchanges are similar to banner exchanges in all ways not including the smaller size of the graphical advertisements. Button exchanges generally lack the large-scale membership numbers of their banner counterparts. They have a propensity to come and go, with few becoming household names. Some place exchanges, particularly webmaster related, have used the micro-button effectively. While small in size, the micro-buttons allow a site to earn more views per page.

WEB RING:-

It means for navigating a group of related sites for the most part by going forward and backward. Web rings are large-scale working class phenomena made up primarily of small or middle size sites. The number of web rings and member sites runs into the millions. Anyone may create a web ring on just about any theme, as the mixture of current web ring topics will indicate. After creating a ring, the ring owner is responsible for attracting and appreciative applicants. Approved sites become part of the web ring navigational structure. The primary means of navigation is using the "next" and "previous" links, although other options such as "random site" and "complete list" often exist. The original web ring system, originally located at webring.org is still the most popular.

BARTER:-

Advertising bartering comes in all shapes and sizes. Some top-tier sites discuss large-scale barter deals directly, effectively putting millions of unsold impressions to good use. Many small sites use banner exchanges as a way to increase their reach. The terms of a barter agreement are often limited only to the creativity of the participants. They can involve trading standard, turning parody. They can also involve trading beyond-the-banner site sponsorships featuring numerous fixed placements of varying formats. The main consideration is to make sure it fits with the goals of the site. Also, make sure all parties involved have a clear understanding of the agreement details.
