Huge Drop in Search Engine Positioning for all My Websites

[tsafarog]

It is very frustrating for me now as however hard I tried to find the reason behind the sudden drop of rankings of all my websites, I am still not able to make out where is the problem. I own 5-6 websites (to name few- http://www.love-lectures.com , http://www.mendatingmanual.com , http://www.datersmanual.com) which were hosted on asmallorange server for the time being. But now I have noticed all my websites have dropped their rankings and almost disappeared from google though the pages are still in the google index. I am not able to figure out where I went wrong though I have always followed the seo guidelines and never involved in any of the activities which may harm my search engine rankings. My site http://www.love-lectures.com ranked 3-4 for the keyword "free relationship advice" but now I am not able to locate my listing for this keyword. Is that my server? or is it me? who should be blamed for, though I have shift all my websites from one host to another host. Will that work? or is there anything else that I need to work upon..... Any help would be highly appreciated!How long has it been since you noticed they all lost positioning?It's been 3-4 days since I have noticed these changes... can you please suggest me what actions I need to take to recover from this... and achieve the rankings as they were before....I wouldn't touch anything right now. I track hundreds of keywords and see this type of thing all the time. They even call it the "-950" penalty. What usually happens is that they drop site's keywords out for a short period of time and then place them back.This has happened to me plenty of times. Just be patient right now and don't make any changes. If you don't see them back in a week or two, we should re-look this.Also, my other website http://www.mendatingmanual.com pages results in the google warning "THIS SITE MAY HARM YOUR COMPUTER" when I enquired about this, I got to know about the issues of badware or any other malicious code that may be present on a website but to my knowledge I haven't been ever involved into such practices.... I re-examined the code, removed any third-party ads, changed my host but still the same problem persists.... I don't know what to do now. Please Advice!
