Instead of immediately sponsoring a Search Engine Marketing (SEM) campaign for certain keywords, keep an eye on your competitors for the best moment to do it. An SEM campaign implies a daily expenditure that most companies can’t afford long-term, so they won’t keep it up for long. If you are determined to spend some money on it, don’t just go crazy and then measure your ROI. After 3 – 4 months of watching, you should know if it’s worth it for your business to spend money on search engine ads. For an advanced strategy, try to identify your competitors’ timing for purchasing search engine ads, and try to replace them when they are not actively sponsoring results.
Now the ad servers don’t create this table themselves, they license it from another company like MaxMind or DigitalEnvoy, whose primary business is geolocation data. This is no enviable task; IP addresses themselves don’t necessarily have an obvious pattern in the way they are assigned like a telephone area code would. It’s a bit like solving a mystery, and the geolocation companies use a variety of methods to approach the problem. /injects>
