Thizizit advertisers get a fixed position in the directory based on the keywords (search terms) they select and the date they sign on. So when a user searches for your keyword, your listing will show up in the same place every time. Unlike a ppc search engine that pits you against secret bidders in a mysterious ranking system, Thizizit employs a simple, predictable formula to determine your place, and once it is established it will not change for the life of that listing.
