Hi There my site ranking dropped suddenly today for my main keywords such as security companies in london and security services in london from first page to 4th-5th page. these keywords were ranked on homepage http://www.armstrongsecurity.co.uk/ other keywords from some internal pages, such as this one http://www.armstrongsecurity.co.uk/security-services/event-security-london.html theygot hit slightly and went couple of listings down the road for event security london, event security companies london as well. same slight hitting happened on this page for main keywords http://www.armstrongsecurity.co.uk/bodyguard-for-hire-london.html can anyone help me, how to get the rankings back? my site authority is around 60 which is far better than most sites ranking higher than me now. these are some problems that i understand so far. keyword rich anchor text link profile for my main keywords over optimised pages let me know if anything you might find suspicious on my site that i can fix either on site or in my link profile. looking forward to your help. thanks gill
