You can create projects in AnswerThePublic, so if you don´t know how to do that yet, please check out this guide Creating a Collection to Organize All Your Searches.
Once you have the project created, now you can add specific keyword searches to be tracked in that project.
You can perform a search from the Dashboard screen as usual and at the top of the report, you will find the Add to Project button as shown in the image below.
After clicking on that button, a pop-up will appear and ask you to type in the desired project name and then add it successfully by clicking on the Add Now option.
You can add keywords to a project directly from the searches History only by clicking on the 3 dots menu on the right side.
Adding your search to a specific project will help you save time finding the search history and organizing your collections in case that you have more than one niche being searched.
