How Accurate is SpyFu? We Back Up Every Claim We Make

Making big claims to your clients is gutsy, so we document evidence of every single advertising claim made on SpyFu.  Finally, we’ve trumped the delete button on ad campaigns.  History is locked in place, and if we said it happened, we can back that up.

Is SpyFu accurate?  We pull back the curtain and let you see for yourself.

Our cached pages of every Google SERP we’ve captured clears up any question about which domains appeared on the keywords we ran.

  •    Illustrate to a prospective client that you can help them focus their campaign
  •    Account for broad match combinations you hadn’t considered
  •    See the full URL/content that triggered an organic result

Another solution, like in this next example, explains exactly why a competitor showed up on a word that didn’t seem right.

Barnes & Noble, for example ( advertised on “Book flights to Corfu”, a luxury  destination keyword that draws advertisers like Kayak, Travelocity, and Lufthansa.  Barnes and Noble was attempting to match on the “Corfu Book” element since they likely sell books on this Greek island.  Sure, a large advertiser might lose track of a few words, but they would easily scoff at the notion of having advertised on something in a heavily competitive (not to mention unrelated) industry.

We can prove it, though.

Let’s find that keyword and go look at the screen shot of the SERP we saw on that date.  (“View cached page” is available just below the first set of stats on all SpyFu keyword stats pages as well as a link inside Ad History individual ads.)

Where Barnes and Noble attempted to cash in on travel books, they were matched to the expensive keyword that would have left a site visitor totally stranded.

An advertiser this big might never know how mistakes like this act as a slow leak in their budget.  But it’s not just limited to large advertisers.   Any domain is a candidate for a broad match misfire.  If this is you, build a double-check into your ongoing SEM research. It gives you better understanding of why a competitor might have a particular term in their history.

Cache goes back as long as we’ve been around.

The cache gives you assurance in what you’re seeing.  We stand behind our data-absurd or not.

Leave it to those whose profession is to dig for facts to put our cache into action.  During the 2008 United States Presidential campaign, The Washington Post turned to us on word that the main website for candidate John McCain ( was advertising on the keyword “hot wife.”

By the time a visitor could type that term into Google, the resulting ad could be long gone.   Without our cache, there was no proof of such a seemingly absurd claim.

However, captured and locked in time, is the result page.  July 2008, page 2.
