I ran across the following ad on Stack Overflow, and I had no idea what GIS actually is.
It would be better to show the full name of the topic instead of just GIS.
GIS stands for Geographic Information System...
does that help? :-)
To answer your question, yes the ads could be a bit more clear...that would be more helpful and attract more clicks.
Well, maybe if you clicked it, you could find out what GIS means?
So this is pretty much [status-bydesign] from my perspective..
