Google Adsense

Surveys should be kept short and sweet, but are an
excellent tool to discover what people are looking for and
what you might be able to provide to keep them coming
back. Use yes/no questions or multiple choice so it doesn’t
take a lot of their time. Also, offer an incentive for taking
the quiz, like a free e-book or a discount on their next
purchase on your site. Not only will you receive their email
address for future updates and lead them to return to your
site, you’re also learning what your targeted audience is
searching for. This will help you expand your site and
increase your visitors, therefore CTR.
