Not quite true: you infringe a patent if you infringe any one of its
claims. You can do anything from the description if it isn't claimed
(this is quite common, because they would have tried to claim something
based on some part of the description but that particular claim got
zapped by the examiner before it issued, e.g. on the basis of prior art).
In this case though claim 1 and the abstract are actually quite close to
each other. They seem to have got it past the examiner pretty unscathed.
What they are doing is crawling web pages, pattern matching for
addresses, phone numbers (which they can relate to a location using area
codes) postcodes etc. and then returning search engine results
prioritised on proximity of between the searcher and the location
they've determined for the web site (or parts of it).
While claim 1 is pretty general (as is usually the case), dependent
claims cover things like relating addresses found on one page to pages
in the same site without addresses on them, specifically contact pages
implying a location for the whole site.
