Buyer intent signals are a prospect's interest or readiness to buy a product or service that solves a problem that they're looking to solve. Classic examples are downloading an ebook or case study, signing up for a demo
or free trial, and attending a webinar - these are all clear examples of someone looking for more information to purchase in the not-so-distant future.
More covert buyer intent signals are spending time on your webpage, on your pricing page, reading reviews, or asking about your company as an option - all of these you can also leverage into a sale.
As a salesperson and as a company, you need to keep a lookout for these signals, as these will help you close a lot more, a lot faster, and a lot more efficiently.
