If you're into SEO and you've been working hard on building In-Links and webbing posts together on sites like Squidoo and HubPages it is nice to see it when your site randomly jumps a few spots in the search engines. Sometimes it gets really frustrating when you've been building for awhile and you don't see any results. If you're super impatient like me, sometimes it helps to have a small bit of gratification early. There are a couple of ways to tell whenever your site is going to jump up. First, it will start to move up and down from where it was at in the search engine. It may drop a few ranks, and then the next day it might be a couple of ranks higher. This is good! This is just google testing your site to see if it holds any clout while in a worse position, or see if it gets more clicks in a better one. Your site will probably move up within the next week or so! Another way to tell is your site's ranking on the weekends. Typically google will have a different ranking for sites that are going through changes on the weekends. It will normally be higher than usual. When Monday comes around it will drop back down more than likely, but sometime in the next week you should experience a permanent change. Just a couple of things to look out for!

Actually its natural. when you build backlinks to any site. Google surely update serps and its done like ups and down. Also why it keeps on dancing is google will not find all your new links immediately. It goes natural if you do not ping the new backlinks. One reason for Google serp dancing is mainly occurs because the creation of backlink that occurs more then the desired ratio that can be felt as natural by The google algorithm.
As we can see that Google is taking priority to real search and including real search time results in the search engine result pages and this is the fact when you make a back link for any your site, it's not affect immediately, ya it shows effects but later on, improves your page rank and your ranking in the SERP,s. The changing in your results referring to the keyword ranking based on various factors and that included all your on page and off-page efforts.
