If you've ever noticed how Google will offer suggestions to complete your search query, you're seeing Google Suggest in action. Web Seer lets you pit Google Suggest against itself to see how many completions match up between search terms.
If you type in "Why are dogs so" into the Google query box, Google Suggest will give you a list of the most popular completions for that query — as of this writing the most popular suggestion is "so loyal" for dogs and "so cute" for cats.
What if you wanted to compare the suggestions for two different queries though? Web Seer takes the Google Suggest entries for whatever two partial queries you put into it and then draws a weighted chart to show two sets of information: what the two phrases have in common and the number of hits for each completion, shown via the weight of the arrow drawn. In our test of the service, in the screenshot above, we compared "Men want" and "Women want" and the wisdom of crowd via Google returned the age old pearl "What they can't have".
