Currently how the advanced search works is that you need to be in the category view in order to refine the search further. There, users can refine search based on location and any other custom fields which you as the admin determine for the site. You can see this in the sidebar of the
ClassiPress demo site as "Refine Results". The fields which appear are determined by the fields you place in the new ad form. So essentially the functionality is there, but it doesn't display in the homepage as you're describing, so it would involve some customization of the default theme on your part if you were looking to have this appear differently. ClassiPress is not encrypted, so you are free to make such changes if you wish.
In the "Advertising" tab of the
ClassiPress admin dashboard settings you can find where to place Adsense code in the header banner or single ad pages, and you can use
widgets in order to ad additional advertising spaces in the sidebar and footer.
You can create a custom ad form which leaves out the price part of the listing, however you may need to do some minor code modification in order to remove the visual pricetag image from the listing itself. Thanks.
