To understand what is Search Engine Marketing, it is must to understand both paid and unpaid means of Search Marketing.

We also have a handy Help Center article on how to create good titles and snippets20.

This perspective will put you at a significant disadvantage. It’s not uncommon for companies to run PPC campaigns with uncapped budgets. Why? Because you should be generating an ROI anyway. This chapter walks through the basics of how.
