What should I do with these keyword suggestions?
Once you start receiving suggestions, move the ones you want to keep to your ToDo list. Then use them to add quality content to your site. If you have a blog, use the suggestions as your writing topics. If you don't have a blog, you can create new pages using these topics or incorporate them into existing pages on your site.
Another option is to use them as link text when building links to your website. Google likes to see a variety of link text in the links that point to a website. HitTail suggestions are a great way to vary your link text in a natural, but beneficial way.
You can also use suggestions in your Pay-Per-Click (PPC) campaigns. This has proven to be very effective because the keywords are not as competitive and are therefore less expensive. In fact, as they are more targeted, they often have higher conversion rates too.
You can even incorporate the suggested phrases in your email marketing campaigns or use them to create your own editorial calendars.
Once you've incorporated these topics, simply check items off your ToDo list and move on to the next!
