The site looks rather fake or like those selling “get millionaire overnight” ebooks, but that’s what I’ve found on google so far. I would appreciate your opinion.

I’m interested in geotargeting and would like to ask you two questions: Can this php code work alongside w3 total cache plugin? I was told both are incompatible…
Also, I want to geotarget countries _and_ cities. Can this be done?

Thanks in advance!

Combining these two should yield a pretty good process.

Really the main, singly most important thing, is being able to find the nearest city of a certain population. It is imperative to make it believable to the user by not displaying whatever podunk town they happen to live in.

Basically it's just a wrapper around free maxmind database, but with nice wordpress integration: country-based contents, redirects by country, country personalization (country name & flag).

I would probably wrap the code they provide in a function with the same name as the one that Patrick used in the example so you can use it like this:

geoip_country_code_by_addr($gi, $REMOTE_ADDR);

MaxMind recommend for speed an disk space usage that their binary format and APIs be used rather than importing into MySQL. I’m dubious that this would be faster but since it’s at least two years since I did any benchmarks on this I can’t be sure. Be sure to leave a comment if you do any benchmarking.

One useful hint if you are importing this into a MySQL database: Don’t forget to make the IP number fields BIGINTs rather than just plain INTs. Otherwise the last 1/3rd of the IP address space will all map to the same location.

Browsers send a language header with every request that is usually based on either the language setting in their OS or the version of the browser that the user downloaded. As you mentioned, choosing a language based on a GeoIP lookup can be fraught with danger. I travel a lot but I still only really know English, even when I’m in Italy or Germany. The language header can also provide fallback languages so if a user indicates that they know Spanish, Portuguese and English in that order, you can try to serve your site in which ever of those languages you have available but you should prefer languages that they know the best.

My language header currently looks like this, even when I am in another country:

Accept-Language: en-us,en;q=0.5


I really should change it to en-gb…
