Keyword Research Tools
You cannot have a successful search engine optimization campaign without keyword research. Your website must show in search results for key phrases that indicate interest in your products/services and deliver some kind of benefit to the company (sign ups, purchases, downloads, etc), so it’s important to find and test keyword phrases.
Keyword Research Tools
Google Keyword Tool – Search for keywords in over 50 languages. It features a very high quality, clean and frequently updated keyword database, with estimated search volume. The down side – keywords that don’t meet Google’s search volume criteria don’t make it to the database, rendering this tool useless for long keyword phrases (four to eight words in length). Regardless, this is one of the best keyword research tools.
Wordtracker – Their free tool has a limit of 100 results. If you want to see all keywords, you must pay. Its free database is very detailed, so in most cases 100 results is enough. Wordtracker gathers keyword data from two meta search engines – Dogpile and Metacrawler. Both search engines hold around a one percent market share, so to estimate real search volume numbers across all search engines you must multiply Wordtracker numbers by 99.
Keyword Discovery - This tool has a noisy database, so use it with caution. It gathers data from toolbars installed on many computers.
