Geotargeting
{{Short description|Website content based on a visitor's location}}

In geomarketing and internet marketing, geotargeting is the method of delivering different content to visitors based on their geolocation. This includes country, region/state, city, metro code/zip code, organization, IP address, ISP, or other criteria.{{cite book|first1=Michael|last1=Freedman|first2=Mythili|last2=Vutukuru|first3=Nick|last3=Feamster|first4=Hari|last4=Balakrishnan|title=Geographic Locality of IP Prefixes|publisher=Internet Measurement Conference (IMC)|date=2005}} A common usage of geotargeting is found in online advertising, as well as internet television with sites such as iPlayer and Hulu. In these circumstances, content is often restricted to users geolocated in specific countries; this approach serves as a means of implementing digital rights management. Use of proxy servers and virtual private networks may give a false location.{{cite news | url=https://www.nytimes.com/2009/03/16/technology/internet/16privacy.html?ref=technology | title=Many See Privacy on Web as Big Issue, Survey Says | work=The New York Times | date=March 15, 2009 | access-date=February 12, 2014 |first=Stephanie|last=Clifford}}
Geographical information provided by the visitor
In geotargeting with geolocation software, the geolocation is based on geographical and other personal information that is provided by the visitor or others.
=Content by choice=
Some websites, for example FedEx and UPS, utilize geotargeting by giving users the choice to select their country location.{{Cite web|title=Location-Based Marketing: Geotargeting vs. Geofencing|url=https://insights.digitalmediasolutions.com/dtc-subscription-marketing-news/what-is-location-location-based-marketing|access-date=2021-09-20|website=insights.digitalmediasolutions.com|language=en-US}} The user is then presented with different site or article content depending on their selection.
=Automated different content=
In internet marketing and geomarketing, the delivery of different content based on the geographical geolocation and other personal information is automated.{{cite news|first1=Emily|last1=Steel|first2=Julia|last2=Angwin|author2-link=Julia Angwin|url=https://www.wsj.com/articles/SB10001424052748703294904575385532109190198?mod=googlenews_wsj|newspaper=The Wall Street Journal|title=On the Web's Cutting Edge, Anonymity in Name Only|date=August 4, 2010}} A good example is the Ace Hardware website at www.acehardware.com. The company utilizes geolocation software to power the “My Local Ace” section of its website. Based on a site visitor's location, the website's online locator service can show the visitor how many stores are in their area, as well as a city-level locator map to help the customer find the store closest to their address.[http://www.gsicommerce.com/assets/docs/pdf/generic/CSA-AceHardware-Nov08.pdf Chain Store Age, “Making it Personal”, November, 2008] Different offers may be presented depending on local conditions, e.g. weather, local competitors, local trends, etc.
IP spidering
The automated discovery of user person/organisation/city-level geolocation information based on IP addresses by traceroute, pings, and a combination of other tools and methods is far more advanced.{{cite web|url=http://www.adexchanger.com/online-advertising/digital-element-rob-friedman-ip-targeting/|title=Digital Element Finding Demand for Granular IP targeting|access-date=2010-04-28|date=2009-08-20}} Discussing automated spidering technology
It is dependent on the pre-analysis of the entire IP address space. There are more than 4 billion possible IPv4 addresses, and detailed analysis of each of them is a Herculean task, especially in light of the fact that IP addresses are constantly being assigned, allocated, reallocated, moved, and changed due to routers being moved,{{cite news | url=http://bits.blogs.nytimes.com/2008/02/22/google-says-ip-addresses-arent-personal/?_php=true&_type=blogs&ref=technology&_r=0 | title=Google Says I.P. Addresses Aren't Personal | work=The New York Times | date=February 22, 2008 | access-date=12 February 2014 | first=Saul|last=Hansell}} enterprises being assigned IP addresses or moving, and networks being built or changed. In order to keep up with these changes, complex algorithms, bandwidth measurement and mapping technology, and finely tuned delivery mechanisms are necessary.{{cite news | url=https://www.nytimes.com/2012/05/03/technology/personaltech/how-to-muddy-your-tracks-on-the-internet.html | title=How to Muddy Your Tracks on the Internet | work=The New York Times | date=May 2, 2012 | access-date=12 February 2014 | first=Kate |last=Murphy}} Once all of the IP space is analyzed, each address must be periodically updated to reflect changes in the IP address information without invading a user's privacy. This process is similar in scale to the task of Web spidering.
IP delivery in SEO
{{main|Cloaking}}
Websites utilize IP delivery for search engine optimization (SEO) in a method called cloaking. SEOs maintain a list of IP addresses that are known to be servers owned by a search engine and used to run their crawler applications (spiders). The visitor's IP address is compared to the list, and if it is determined to be a search engine spider, it is presented with different web page content from human visitors. Cloaking is against most search engines' webmaster guidelines.[https://www.google.com/support/webmasters/bin/answer.py?answer=35769 Google webmaster guidelines][http://help.yahoo.com/help/us/ysearch/indexing/indexing-14.html Yahoo! search content quality guidelines][http://search.msn.com/docs/siteowner.aspx?t=SEARCH_WEBMASTER_REF_GuidelinesforOptimizingSite.htm MS Search guidelines for successful indexing] {{webarchive|url=https://web.archive.org/web/20060819035446/http://search.msn.com/docs/siteowner.aspx?t=SEARCH_WEBMASTER_REF_GuidelinesforOptimizingSite.htm |date=2006-08-19 }}
Although search engine guidelines imply that any type of cloaking is bad, there are instances when the practice may be legitimate. The subject is very controversial and continues to be debated by SEO experts.{{cite web|first=Chris|last=Sherman|date=July 18, 2001|url=http://searchenginewatch.com/showPage.html?page=2157341|title=Search Engine Cloaking: The Controversy Continues|website=Search Engine Watch|archive-url=https://web.archive.org/web/20071113063408/http://searchenginewatch.com/showPage.html?page=2157341 |archive-date=November 13, 2007|accessdate=December 9, 2007}}
"Cloaking" via IP delivery is different from cloaking via "user agent". While IP address spoofing is harder and more reliable than user-agent spoofing, it is also harder to keep the list of IP addresses used by search engines for their crawlers up-to-date. An outdated list of active crawler IP addresses enables the search engines to detect cloaking and may result in a removal of the site from the search engine's index.

- City advertisingSearch Engine Optimization for Dummies, 3rd Edition, 2008, by Peter Kent, Chapter 10 'Finding Traffic via Geo-Targeting' by advertising on web sites with extensive content related to particular cities. Such websites can connect large city audiences with products/services for sale in those cities. Surfers searching for information about particular cities find adverts on such web sites as a result of city name related searches rather than product/service keyword searches. In this way businesses, e.g. shops, restaurants, can advertise and reach out to consumers located in the real-world localities of their product/service offerings.
