View Recommended Budget
Analyzing budget ...
Your budget is OK. We don't recommend changes at this time.
Delivery method: Accelerated: Show ads as quickly as possible
Ad serving: Optimize: Show better-performing ads more often
CTR: 1.96%
any help?
I would suggest changing the delivery method to show over a longer period of time. I would also change the ad serving to rotate evenly. If you aren't doing it, try creating more ads for your ad groups to see what performs better. That's a good way to increase quality score, thus lowering your overall cost per click and ad position.
Historically, though, if an ad is showing - but is not showing all the time - it's usually a budget issue.
[...] My daily budget is what google recommended. I even set $1 per click. [...]
One thing to note is that if you checked for the recommended budget and then raised your Max CPC - the recommendation you received will no longer be accurate. This is because fewer $1.00 clicks are possible within a given budget than clicks at a lower Max CPC.
You might want to consider a short term experiment: raise your budget to the absolute maximum you'd be willing to spend in a 24 hour day, and then let the ad run for a day or more under that budget - and see if this causes your ad to show more often.
Don't forget to lower it back down, however. ;)

The option you set for delivery method (accelerated) would explain why your ads are disappearing so quickly. Definitely change to 'evenly over time'.
I have to confess I don't use the Google budget recommendation tool, I have my own internal methods for calculating my budgets in combination with Impression share reports, historical data etc. However just an idea, is there a potential difference for country settings. ie. the suggestion tool only based on one country data but you have a your campaign set to all countries? (just thinking aloud on that last point).
