For $100 per month, Affinity will create, execute and manage a small business customer's search campaign. The ValueTraffic plan guarantees at least 10,000 monthly impressions or 50 Web site visits. Meanwhile, LaGarde is charging set-up and monthly fees for its combination of search and e-mail marketing services. Those fees start at $9.95 for set-up, and $200 to $300 per month on the low end. LaGarde will also design e-mail creative, for an additional fee. The end result is that both Affinity and LaGarde will be going head-to-head in an already crowded arena. Earlier this week, Web hosting giant Interland (which, too, has made successful forays into the add-on services market) launched its pay- per-click search marketing practice.
