title: Efficient way of eliminated fake traffic from visitors stats?
body: <p>I am working on my own web stats script.</p>
  
  <p>Successfully eliminated many bots. Problem is only with tweet, when i tweet a link immediately i see <strong>20-30 visits</strong> on URL that i suspect are <strong>cURL/unknown spiders</strong></p>
  
  <p>What is the efficient way of detecting such visitors? I want to improve visitors stats.</p>
  
  <p>P.s. These visitors are not reported/seen in Google Analytics and for bots i remove these user agents from stats:</p>
  
  <pre><code>&lt;?php 
  array(
      "Butterfly","Twitturls","Me.dium","Twiceler","facebookexternalhit",
      "Teoma", "alexa", "froogle", "Gigabot", "inktomi",
      "looksmart", "URL_Spider_SQL", "Firefly", "NationalDirectory",
      "Ask Jeeves", "TECNOSEEK", "InfoSeek", "WebFindBot", "girafabot",
      "crawler", "www.galaxy.com", "Googlebot", "Scooter", "Slurp",
      "msnbot", "appie", "FAST", "WebBug", "Spade", "ZyBorg", "rabaz",
      "Baiduspider", "Feedfetcher-Google", "TechnoratiSnoop", "Rankivabot",
      "Mediapartners-Google", "Sogou web spider", "WebAlta Crawler","TweetmemeBot"
      );
  ?&gt;
  </code></pre>
  
  <p>Thanks</p>
