If you are into seo and like to know how well your website or blog is doing, then you might check your traffic levels on a regular basis. Don’t be surprised if you see large spikes in the traffic, it could be that someone has stumbled your post on stumble upon, or posted it on Digg. If it is a downward spike then it could be that there is something wrong with your sign up form; errors on this can prevent conversion.

Sometimes a spike in the traffic levels is not due to traffic referrals at all. Occasionally it could be down to the market where products or information such as you are offering have taken off. Sudden spikes in the traffic are not hard to analyse and are always worth investigating. You may be getting less useful traffic because the number of bounces on your site have increased, this could be due to an erroneous redirect. The reasons for a spike in the level of traffic to your site could be caused by any one of the above reasons. If you are not sure what the spike is a result of then you should use Google analytics: running a number of reports could help you to identify the problem.
