To keep things simple, you may try IP based redirects on your server. You can setup simple redirects based on geolocation, using .htaccess or httpd.conf on your Apache server (mod_geoip). The GeoIP API (MaxMind) will enable you to quickly configure your server to divert traffic according to the originating IP. Your web analytics and optimization should do the rest. All you need to make sure it that you have a couple of landing pages to test your assumptions on.
The first case is quite simple yet happens often. So for example, you have not sold tandem bikes for years (and had the word “tandem” in a negative list), then you started to sell them again. But your PPC specialist forgot to remove the word from negatives, and now you are left wondering why you are not getting any traffic for this keyword. To avoid this situation, check your negative keyword lists regularly and bring the relevant keywords back to life.
Before we can create our campaign we must clearly understand our target audience. This will help develop the campaign structure and inform the way you create the campaign.
