I had trouble finding a definitive answer, I suppose that's because there isn't one since it's all relative. I'm tinkering with seo for a site for a local business. When purchasing traffic I notice that a lot of places offer large amounts of traffic and don't drip-feed small amounts. Could it have a negative impact on a small site to go from around 100 visits a day to 500 or 1000? In general what could constitute as too much traffic and raise a red flag? I'm also assuming that a big decrease in traffic can be just as bad if not worse. Again, I realize that there are no definite rules for SEO, but I'm looking forward to hearing everyone's thoughts on traffic.
