Easy improvement with a bing bang for your development efforts:
- when you display the results of a niche search, show with a simple label whether the niche was:
APPROVED (OR FOR SALE)
Please also consider showing a date for each label, in other words:
The date the niche was rejected
The date the niche was approved
The date the niche was purchased/became active
When people search niches, they will often be trying to determine whether another niche is redundant, or whether a niche exists that they can buy. It is impossible to know this by looking at the current list of results - one has to click on all the niches in the list to learn this information. Some results lists will be huge - consider a search for 'crypto', for instance.
Dates can be important in determining which of two niches came first, which will be important in resolving niche clashes.
