If I want a normal text ad but with only 2 or 3 text units how can i do that? Seems it only gives me options for 4-5. Thanks
I think you are confusing ad link units and regular ad units. Ad link units have an option of 4 or 5 links. You cannot select the number of ads at all in regular ad units.
This is correct as they will place ads that are relevant to your site, so you may see 1 or 4 depending on your content.
If you really just want two ads, place two of the one-ad-only ad units (like the half-banner) side by side.
