Hello Thomas.
The answer to that question depends upon alot of things.
Are you focusing on a small niche, or are you going after something more competative?
What kind of conversion rate can you expect in your niche? Is your site product related?
Are you expecting return visitors?
How do you plan on monetizing it?
First off, don't make the same mistake I made. Broad search and exact search are completely different, make sure you check the appropriate box.
When most people talk about monthly search volume, they are referring to exact monthly searches. Every situation is different, but many people look for a minimum of 1000 exact monthly searches, for a closely targeted niche. I like alot more.
What's the competition like? Google the search term and check on the quality of your competition. Are you completely depending on SE traffic or do you have other ways of getting people to your site.
If you plan on monetizing your site, figure out how before you register a domain. On Google adwords tool go to right side and click on the "columns" drop down menu, and check estimated average cpc. If you plan on using adsense this will give you an idea about monetization. The figure shown is NOT what you will be paid per click, it is what an advertiser might expect to pay for a max bid. If the figure is below 50 cents you will probably be pain pennies for that term.
But even if adsense clicks are low, there are many affiliate programs you can check out.
Global vs. Local-This is another area that gave me a HUGE headache in the beginning. Will you be advertising something like an e-book, or something that has to be packed in a box and then shipped. It all depends on your site and how you plan to monetize it. Who are your users? You have to do lots of reading.
I go by Global results now because I found an affiliate program that has merchants available in several different countries.
Research before you register...
