David McDaid: We've dropped from #1 to #6 for two keyphrases which we were #1 for, for years. ; Can anyone help determine the cause of this?
G.S. Marjara: +David McDaid there could be tons of reasons, you must share more details like, dropped KPs, URL etc so that one can evaluate to help you.
Cody Baird: +David McDaid forgive me for not taking the time to do an analysis on your site. I will share that there have been major disruptions in the past few weeks. I wouldn't worry if your ranking drop was very recent. You should rebound. If it was not recent and is lingering - deeper analysis would be recommended.

Ashish Ahuja: 1 to 6 is not a huge drop its just shuffling, the site will come back up on its own or you can improve the onsite content, structure, internal linking and add some more high quality links to get back up
Jim Munro: HI +David McDaid ;- please disable the link to your site in the comment. We usually do it like this: ;www.silkblooms (dot) co.uk. Thank you for your understanding.
Please remove the link to your blog, +David Harris ;. I regret that I do not have time to spare to read it for myself this morning. I'll take it as a given that it is an authoritative site that provides the best answer to David's question but self-promotion of your site is not permitted here although you are free to express your reasoning in the best way you can to address the question. Thank you for your understanding. ;
Never mind. I deleted the comments - please check our simple posting rules on the top right of this page.
Aamir Siddiqui: It could happen due to Google dance terminology. But you should regularly check the SERP behavior and do competitor analysis that on what metrics your competitors are above your website. Your content should be more interesting and the website should be more user friendly. Thanks.
Clement Low: As much as you trying to rank a keyword, so does your competitors. Check who had replaced your position and do some competitive analysis to help you to determine the cause.
Emmanuel Flossie: Create an article or page that is associated to your particular page. Inbound page links will ultimately bump up the targeted page's rank.
Clement Low: +Emmanuel Flossie is that so simple? Did you actually did that before? Are you based on your own real experience or just merely comment for the sake of commenting? Please don't misled op.
Emmanuel Flossie: It helps yes, I'm not saying that it will bump you to number one. I currently work on two of the biggest niche ecommerce sites in the UK that I have done and work.
Ashish Ahuja: +Clement Low I agree with +Emmanuel Flossie to some extent if you create relevant articles and link to the page you want to rank it creates a silo / tree like structure so google increases the overall authority of the site for that topic and if the articles get some good external links then its even better. But in current case I ; don't think OP should do anything other than improve onsite structure and content, google sometimes checks if the site is being actively monitored and SEOed by making the site dance (it has a patent for the same) and if webmaster does nothing then it brings the site back up.
Jim Munro: Hi Ashish, please give me a link for "(it has a patent for the same)"
Ashish Ahuja: +Jim Munro here's the link http://econsultancy.com/in/blog/10635-the-google-patent-trap-for-rank-modifying-spammers discussing this patent
Jim Munro: OK. Thank you for that. Here's another I stumbled across that ;discusses the same subject further: ;http://dejanseo.com.au/the-random-google/
