Hi there,
How does Google know to place your advert regionally - is it by ISP or an algorithm?
Do people find the miles radius works better or not?
Does it also go Nationally anyway?
The AdWords system may analyze a searcher's query (for example "London florist") to establish what location that person is searching for. The system may also take note of the person's Internet Protocol (IP) address to see where he or she is searching from.
Your results will depend a lot on your market and product/service.
