Arcade Webmasters until about 18 months ago, linking strategies available to arcade webmasters had two options available in the multitudes of arcade scripts in the marketplace. One method built into most of these scripts, provided an administrative backend to manage the links, allowing the site webmaster to display and sort links based on how many hits arrived from the linking sites on a daily or overall total. Other sorting and display options were also available in some scripts some of which detract from the links value. Well built scripts also have functions available to allow the incoming webmaster to submit their link information to your site.
This linking method typically displays all link trades on a single page of the site. For X amount of link partners this method also displays a limited amount of links sitewide based on the criteria the webmaster has chosen. Options typically used for sitewide display are the number of hits incoming from that site each day or overall total number of hits received and can tack number of outgoing hits too.
Recently, this type of linking has lost much of its value as some sites treat the links badly if incoming traffic is poor or not high enough to display the links at all. Some scripts and webmasters are also now adding no rel follow tags to these outgoing links. However, that alone is not a reason to not trade links with the site and if you utilize the newest form of link trading you can actually form good alliances in this niche if your site is actually capable of sending many visitors to your partner site.
The newest method is typically referred to as traffic trading. Some of the newer arcade scripts have it built in at purchase and almost all have mods available to add this capability. Numerous options are utilized with traffic trading scripts. Generally, what happens is you sign up with a partner and add links to certain games on your site. When you are due to get traffic (because you sent some prior), your link partner utilizes your game information on his/her site. When his /her visitor goes to play that game, they are redirected (301 redirects) to your site. You now have received a hit from your partner's site and you should then reciprocate utilizing similar method.
Both of these methods can and do produce positive results mostly in direct traffic from one arcade to another. Depending however on how the links are formed, where they are displayed on site, and if they are, actually do follow links you may or may not get positive search engine utilization from these links.
To many webmasters in arcade community, SEO benefits are secondary or non-existent concerns. It is important that you decide what you are trying to accomplish with your linking methods and select your trades accordingly.
For purely SEO enhanced link trading with arcade sites a perfect option for arcade webmasters are hard coded SEO optimized link trades mainly placed in footers of your Arcade pages. These are typically sitewide but some advance SEO'd Arcades are designed to provide super SEO link trades from pages providing "REFERENTIAL INTEGRITY".
These sites deliver link exchanges from main pages and from their category pages to arcade sites that have some referential basis to those pages. Example: From a "Shooting Games" category page to another "Shooting Games" category or site's main page. In exchange for this link, the site may want a link title "Racing Games" from your "Driving Games" category or site main page all depending on the pages theme.
Setup your site to build permanent, hard coded, do follow links, Just as you would do if you had individual HTML pages on your site instead of dynamically created pages that arcade scripts typically generate. Link building this way and you are on the way to some excellent SEO Optimized link trading.
Some things to look for in getting and placing link exchanges. Where will your link be placed? How many outgoing links are being placed on that page (35 outgoing links or so should be max)? Will your link title be reserved as unique from that page (answer is Yes, then you have achieved link exchange nirvana)? Is that page optimized for your link reference (answer should be yes, but sometimes a decent link is better than no link exchange at all)?
Remember the point is to build referential integrity from your arcade pages. "Car Games" to and from Car game pages or site, "Shooting Games" from and to shooting games pages or sites, "Zombie Games" to and from Zombie pages or site.
Hoping you, success with your arcade link exchange building efforts.
