I have a friend who's a travel agent. Right now, if you go to Google and search for
international tickets, the #1 result is her site. This is a huge honking deal to her; that placement alone earns her serious money.
Travel SEO is a very competitive business.
My point: now that it's public, if you want to help this site succeed, please keep an eye out for spam.
User1, who's brand-new to SE, comes in and posts a recommendation for a service. Let's call it Service1.
One recommendation? No problem.
User2, who's also brand-new to SE, shows up less than 24 hours later, goes to the same question, and posts another recommendation for Service1.
Two? And both from brand-new users? At this point, I start to get the might-be-spam vibe.
Later, User2 posts a question asking if should she stay with Service1 (the one she raved about just an hour earlier), or should she go with Service2 instead?
Now, this could theoretically be fine, except a quick search showed that Service2, while claiming to be a consolidator, only ever refers people to Service1, and may actually be the same company.
Given that neither User1 nor User2 have posted anything on other topics, I would flag all three posts as probable spam.
The TL;DR version:
Let's all work together to keep this site clean and useful. If something looks off to you, please flag it so the mods see it as well.
