I ask this question because I notice constantly to the some months. My website sometime up first page website on 3rd no. and after sometime my website go on 2nd page and 7th no.website.
The web results depend on a various of things. The place/region from where you are searching, includes ip and on which search engine your are checking. (Google.de, google.com, google.com.br). For example if you are from united states and you make a search on google.de then it will show you the major INTERNATIONAL players on Google Germany, mostly the .com domains, but with German print.
yes, they modify their ranking algorithm on a regular basis. they usually release major updates every year or every couple of years and make around 500+ minor modification to the algorithm every year so thats like every day
Yes. Sometime my new blog post ranked on 1st page 10 minutes after its publish. Then, on 2nd page the next morning. However, its also depends on your ip and what google you use.
They update their algorithm time to time, in one month, 3 months, there is no exact time, but if you are getting changes day by day then it is because of your link building effort, traffic, content of the website.
