Hey ProductHunt
Other similar tools do not allow accurate locality suggestions meaning you sort of have to guess what the Google UULE (location variable) will be before base64-ing it (don't worry nerdy stuff). So a user could inputted incorrect data like "999999999" and get inaccurate results.
We fixed that approach by using the SERPWoo Project Wizard's locality engine and our sophisticated smart detection algorithms for misspellings. Now anyone can look up results as if they are standing at the particular location - whether it's near your client's office, or on the other side of the world, you will see Google search results, all top 100 results, and more without being limited like the Google Preview Ad Tool.
Obviously if you are looking to track the results (rank tracking) on a daily basis you can login to SERPWoo and create a project with the Project Wizard and go through the simple process of creating a local search project.
