Sure we know we’re tracked as we surf the web. After all, how else do those pants you eyed last week keeping showing up in your Facebook feed? Keeping spending in check is hard work when items we’ve coveted while browsing online keep stalking us on the web. Ghostery may be a solution. The free app uncovers ad servers that have their digital hooks into you—allowing users to block targeted ads if you, or your clients, choose. Ghostery works on nearly any search engine from Chrome to Firefox, IE to Safari, on PCs, iOs devices and those running Android. Plus it’s free for consumers. Give you and your clients a way to keep temptation at bay—and start surfing the web the way you’re meant to—as invisibly as a ghost.
