• 20% of all Google Searches Performed on a Desktop Involve Location
• 40% of all Google Searches Performed on a Mobile Devices Involve Location
ACCESSING USER LOCATION
Implementations
• IP Geolocation•HTML5
IP GEOLOCATIONYou have an IP Address & we know geographically where that is.
IP GEO Properties
• Always On• Static in Nature• No Permission• 25-50 Mile Localization
IP GEO LIBRARIESHow it gets done
• Agreements with ISPs• AppSourcing the Crowd• Mad Scientists with Mad Bots• Wifi Libraries
IP Geo Libraries
Service Providers
• IP2Location• MaxMind• Quova, a Neustar Service
Libraries in General
• 4B IP Addresses• ~ 20% Actively Changing• Accessible via DB, API
Plugins that do IP Geo
• GeoPosty 4,084 Downloads – 4.25 Stars• Quova IP Technology
• IP2Location Tags – 468 Downloads – 5 Stars• IP2Location IP Technology
• WP Geolocation – 1,120 Downloads – 2.75 Stars• MaxMind IP Technology
Plugin Features
• Shortcodes• Preconfigured Widgets• Redirection• 3rd Party LBS Integrations
Obligatory CODE SLIDE
<?php echo do_shortcode('[geocity]'); ?>

HTML5 GEOLOCATIONPermission based access to users’ location.
HTML5 Background
• A collection of HTML standards being brought into adoption.
• Not something that’s going to show up all at once, not even on your birthday. #sorry
• Many features are already in adoption with current browsers.
HMTL5 Geolocation
• A singular feature of the HTML5 Standard• Off By Default• Can be coded as dynamic• Permission Based, Error handling can be difficult• ~ 12 Meter Localization
HTML5 Geolocation APIHow it Gets Done
•Cell Tower Triangulation•Device GPS• IP Geo Libraries
HTML5 Geolocation API
• IE – 9.0+• Firefox – 3.5+• Safari – 5.0+• Chrome – 5.0+• Opera – 10.6• iPhone – 3.0+• Android – 2.0+

Best Practices
• Location, Location, Location with Balance, Balance, Balance
• Give the User A Logical Exit• Don’t Be Evil, Get Consent, Allow Record Removal• Privacy Policy FTW
Never, Never Never Ever

The Basic Geo Loop
<?php
$city = do_shortcode('[geocity]');
$args = array('category_name' => $city);
$myCityQuery = new WP_Query($args);
if ($myCityQuery->have_posts()): while ($myCityQuery->have_posts()): $myCityQuery->the_post();
//post stuff
endwhile; endif;
