Brainstorm Some Keyword Terms
No matter where you're searching, you will need to pick out the most important keywords. These are generally nouns.
For example: "How do advertisers market their products to women?"
Other related words (or synonyms) for products and women might be:
Products: clothing, clothes, cigarettes or liquor, computers, toys
Women: girl, girls, gender, female, females, ladies, mothers
Note that we've included variations of keywords such as plurals. Include any alternate spellings of words or abbreviations, too. For example, turn ADHD into Attention Deficit Hyperactivity Disorder.
