One week back i got one keyword ranking for my website in 2nd page. Now it is in 7th page. I dont know what is the reason behind ranking changes.
There was a Panda data refresh on 19th April, 2012. You also need to check if your website was penalised by the very latest ‘Over optimization’ penalty or the even latest ‘Penguin update’ Here’s Matt Cutts helping you with other possible reasons: http://www.youtube.com/watch?feature=player_embedded&v=gx04qNrCbnk Techniques to follow now? Avoid indulgence in keyword stuffing, link spamming (link trading) & linking the same anchor text to multiple sources. Include unique, informative content in your website and make the most of social media interactions. I think you have to check your website content is it outdated? If it is outdated then update it regularly because quality and unique content is very impotent part of website ranking. You have to use different methods of link building with quality content, and try to use new website for link building.
[h=2][/h] Penguin, along with previous Panda updates, have been very hard on affiliates. In particular, small affiliates have been hit the hardest. Basically, Google is devaluing websites that have too many low-quality backlinks or links from sites it deems unrelated. This would include anyone with a high amount of backlinks from direcories, article submission sites, unrelated blog posts, blog and forum signatures, etc. And they've hit anyone using "linking schemes". Although it's unclear what is considered a "scheme", if you're exchanging links in any way (reciprocal, 3-way, etc.), it's likely you're going to suffer the consequences. There's also been talk of "over-optimization" penalties for webmasters who keyword stuff, or over-use KWs in their backlinks. So for example, if 90% of the backlinks to your website include your core KW (ie: blue widget), then you might get hit for over-optimization. The key is to gain backlinks on highly related, higly relevant pages (think guest posts on related blogs!). And you need to make your backlinks appear "natural". Natural would mean more "fill" words in your link text like: get, click here, learn more, etc. -- with your KWs mixed-in in various ways...
I notices something similar with our companies website. I've only been working here for 3 months and noticed a tone of unrelated, irrelevant links which were created before my time. Literally in the space of a week, keywords which were very consistent and often climbing began to creep down the rankings. The only explanation has to be the Penguin update. Oh well there's nothing like a clean slate to get working on...I better get building some relevant high quality links!
It has got to be backlinks. You can use a back links tracker to find out who is linking to you, or check in Google Webmaster tools. Also, try to clean up your link profile and I'd recommend you getting high-quality, organic backlinks by submitting press releases, guest blogging, and doing similar things. Also, pay attention to anchor texts. It could be the case that the keyword that is often repeated in your anchors was affected. But I can't be sure, of course.
may be you are slapped by the google..try to avoid this problem..submit your site on google webmaster and try to solve all the the issues..
Lots of sites hit after Penguin update. Google has refresh data and pushed out the update to its recent webspam-fighting Penguin algorithm. Check your content for duplicate, unique and quality content. check your back links and update these to recover your keyword ranking.
