My sights rankings all disappeared a few days ago, why? Im not sure whats happaned. Anything to do with pearls-- pearl jewellery, pearl necklace, pearl earrings, pearl bracelet, pearl ring, site below. www. lustrousjewellery. com
http://www.google.com/search?hl=en&q=site:www.lustrousjewellery.com&btnG=Google+Search Looks like the site is still indexed just fine to me, results might be due to changes in algorithm or perhapes you've been losing backlinks. Many reasons why you could have lost your rankings, but apparently your site hasn't been de-indexed. Continue to on-page and off-page optimize your site normally.
Hmm, it's barely 1 year old, so rankings are often not really stable. Lost backlinks would be an explanation as well. Since it's shared hosting with 487 other sites on your server, some (rare) IP penalty not caused by you, but someone else on that IP, could be a reason as well. All speculation, as long as it's indexed I'd keep doing what you did before, add links, wait and see.
one of my sites dropped for a day last week. just keep optimising as you would normally. I tend to ignore any glitches unless they last for more than about 4 days
