Casino traffic is increased/earned by:
1. Pay Per Click engines, (like Overture, Bay 9, etc.)
2. Sponsored ads in Search Engines, like Google Adwords, Altavista Gambling Sponsored matches, Google Gambling Sponsored matches etc.
3. General Searches in the vast assortment of Search engines.
I would stick to focusing your site to either per per click (PPC) or go the free route and get into Google, which is the only worthwhile search engine out there.
DO NOT fall for the lame brained search engine optimization plans that submit your site to thousands of search engines, or profess to get your site ranked in the top 30 in X number of days… These guarantees can not be backed up, and again, the number of search engines that are worth being listed in can be counted on one hand….
When’s the last time you looked for information in one of these so called “thousands of other search engines” that search engine optimization companies advertize? This is the biggest scam out there, and people pay dearly for it.
Reciprocal linking is key. And yes, your site has be online for about a year or more for the Search Engines to fully index it and find it….then, as you edit and add links, etc., allow a month or more for the search engines to ferret them out….this is as much a waiting game as it is trial and error….
