The question of big sites vs small sites and how they rank in Google has always been one of those questions SEOs have asked. In fact, it seems that only 30% of SEOs believe web site size does not matter in terms of rankings.
That being said, Google's head of search spam, Matt Cutts, posted a survey on Google Docs asking you to tell them which small web sites are getting an unfair shot in Google and should rank higher.
Matt tweeted it last night:
If there's a small website that you think should be doing better in Google, tell us more here: https://t.co/s80BibIBhN— Matt Cutts (@mattcutts) August 28, 2013
The survey itself makes it clear that no rankings will be impacted directly from this survey:
Google would like to hear feedback about small but high-quality websites that could do better in our search results. To be clear, we're just collecting feedback at this point; for example, don't expect this survey to affect any site's ranking.
I am glad Google is indeed looking into this.
