With SmartLink DU plugin you can attach up to 5 URLs to a single link and use them in a single anchor text depending on visitor Geo-Localization or randomly.
Every time the page is loaded, one of the 5 URLs you’ve entered will be inserted randomly in the link if there is no GeoTargeting match or if Geotargeting feature is off.
As the link sintaxis is same as a normal link, it works exactly the same. 
There is no risk of being penalized by Search engines, ¡THIS is NOT a black hat Plugin!
SmartLink can be used to make a more impressive internal linking strategy, specially useful if you have tons of content and want to link to your posts more aggressively.
Also it can be useful for essential links within posts excerpts showing in top of the main page, where you can’t add another link and want to use the existing one, linking to several URLs. Also can be used as a link shortener, compressing up to five urls in a single link
You can use SmartLink to show different external URLs to each of your visitors from different countrys using the GeoTargeting feature.
