In addition to the Google Keyword Planner and Bing Ads Intelligence, here are a few of my favorite tools for conducting keyword research for Search Engine Marketing (SEM). Some of them require a paid subscription, but also offer free trials.
- Google.com – Type in a search query and explore the autocomplete suggestions
- Google Trends
- Keyword Tool
- KW Finder.com
- Moz Explorer
- Word Tracker
- Keyword Discovery
I also like to use lots of negative keywords to ensure that ads are relevant to the searcher. WordStream offers a free negative keyword list tool to help you discover potential negatives. Other tools and lists are available from WebMechanix and TechWyse.
