When planning an SEO strategy for directories, you need to carefully measure your actions in order to act with perspective and achieve the best results.
It may be the case that you are considering working in a email database lists poland directory with very well-positioned competitors, but if the appropriate actions are applied we can get ahead, although it will take a lot of time for analysis and field work.
Nothing is impossible with a clear, defined and well-crafted strategy.
If you are going to work on a niche that is not yet exploited (there are still some) with very little to do, you will get qualified traffic, but only from population areas that are not exploited by local directories or other websites that already have the positions you are looking for.
What we want to say from our agency is that it will be very simple to achieve (even with duplicate content) a good ranking in small areas, although you will not be able to use the same strategy for large towns or provincial capitals.
This is a very important detail to take into account, since we cannot despair in finding the locations with the greatest influx of people as quickly as in small towns.
