Can Someone Explain This?

[Licker4U]

I got a new domain in Oct. 06 and since then have 118 free sites, each with 9 mirrors for a total of 1,062 sites. This tool: http://www.seologs.com/indexed-pages-tool.html says I have 1,920 pages indexed in Google.

Traffic has been:

Nov. 06 32,787
Dec. 06 59,693
Jan. 07 72,566
Feb. 07 109,697
Mar. 07 131,420

Most of this is LL traffic with a little SE thrown in. Awstats says I have
for March, 477 different key phrase searches and 389 keyword searches from SE's.

Most of that time I promoted TCG sites, Fetish Hits for a month, and for the last month Silver Cash. If my traffic is going up so much, why aren't sales??? I don't build the best sites in the world but they're not the worst either. With the traffic increase I would think there would be some increase in sales |confused| I never assumed sales would go up proportionately with traffic but at least a little more. Is there a memo I missed?
