I asume you mean the ranking in a search machine index?
If so, keep in mind that this is not the only means new user will discover your website.
A tag on a wall to share a website with local information might be more effective then paying for google adds.
If you're the only website in that city with tags on wall, your local ranking compared to other websites should greatly increase.
...I'm pretty sure that doesn't answer your question, but maybe helps you to rethink your question. :-p.
