Successful online advertising requires ongoing work and optimisation to improve performance and results. Maximising output and reducing input is critical.

No matter how marketing-savvy your company may be, you can always learn more about your customers, especially when it comes to personalizing your advertising. That’s where geotargeting can again be beneficial. The information received from geolocation can help a brand determine where a consumer is looking so it can better tailor events, products, and services to those consumer interests in the near future.
Comparative user testing to the rescue: you ask the participants to evaluate your website as well as the websites of your top 2 competitors.

Not to overwhelm the participants, limit the number of websites to 3 per person.
It is dependent on the pre-analysis of the entire IP address space. There are more than 4 billion possible IP 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,[6] 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.[7] 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.
