There is no way to tell for sure. But, looking at the competitors title tags in Google will give you a good indication of the terms they are trying to optimize on:
In Google type the name of the site URL preseded by a "site:" for eample searhc
This will show you a page with the title tag: " Wedding Flowers in Halifax"
so we know they want to get found on that search term.
Search it and see how they a doing.
