What is the Best SEO Keyword Tool?
An ideal SEO keyword tool should tell you how your customers interact with your site, and should tell you more than just which keywords to optimize for. Good SEO keyword tools should tell you how to organize keywords, and what to do with your newly found keywords to get the most out of your search marketing efforts.
WordStream offers a robust suite of SEO keyword research  tools to help you:
- Find the keywords that people are using to search for offerings like yours
- Optimize web pages with keyword-rich text
- Structure your content into a logical hierarchy
- Understand which pages you should be authoring next
These are some of the most helpful steps you can take in creating a truly successful search engine marketing  campaign, and WordStream's SEO tools can help.
The WordStream Difference: Better SEO Keywords, Every Day
If you're just getting started with keyword research for SEO, you'll probably want to begin by using a free keyword suggestion tool on the web. WordStream's Free Keyword Tool  is a great place to start: We index over a trillion unique search queries, provide more accurate results faster, and return more long-tail keywords than most paid SEO keyword tools.
If you want to dig a little deeper with your keyword research, we offer several other free tools that add even more value to your keyword lists:
- The Keyword Niche Finder - Enter a seed term to get back clustered suggestions of related terms, ready to use in paid and organic search campaigns.
- The Keyword Grouper - Drop in a list of keywords from another keyword tool or your analytics and the Grouper instantly organizes them into a usable structure.
- The Negative Keyword Tool - Find the irrelevant keywords you don't want turning up in your campaigns, driving traffic that won't convert.
You can use these online SEO tools  for free. But SEO keyword research is only truly valuable insofar as it gives you competitive edge and the power to find and act on keywords whenever you need them.
