One keyword of my site was 75th rank. I had submitted approximately 20 bookmarks and 1 Article. But the keyword had gone 610 rank. What is the cause of it. plz. help me?
ohhh, i understood your problem, that is why SEO is not what we do hard to get backlinks, it's all about understanding the search engine behaviour and working accordingly, as per my knowledge the reason for your ranking down is, abnormal behavior of your backlinks, you would have got all these backlinks within 24 or 48 hours, because google can understand that your trying to manipulate the ranking of a webpage, because natural behavior of link acquisition is no that much, your links should look like natural to SE's that means, building many links one day and zero links other day, informs the SE's about abnormal behavior, so while building your links, first build them naturally, like day1 2links,day2 2links, day3 zero links,day4 1link, etc, also the anchor text also keep varying, like keyword1,keyword1 variation etc,,hope this helps.
First of all u check your keyword Competitions and then you should promote your site becoz if your keyword competitions is high then change your keyword then again promote your site may be result must effect of your and please u can do one thing u can promote continuously different different link building functionality u can use that time.
Its Only due to the Google algorithm updation.Another is lots of competition.if your domain is new so its more difficult for you maintain your ranking in SERP. old domain is one of the beast reasons to come up the ranking in top 10 pages instead of new domain.
