why this happened?

i have add some new article in my site.

when i will add new article in my site it will added in 2-3 days in google days.but after 2-3 days it will "d index" again?

why this de index again once it comes in google?

 

The same thing happens to me before.

 

Different Google Datacenters will show slightly different information and it may take a while before the indexed pages show the same at all centers.

Have you searched the individual datacenters to see if your pages are there?
After a few days/1 week, do the pages finally show up or are they gone?

 

some page are come and some time not come in 10 days

 

That is usual and also always happen to me

 

Best thing to do is check your web logs and see if googlebot has visited the page. If so it is indexed.

 

Thanks to ask this question. i have known a new thing.

 

probably a copy pasted article? make sure you test the article with copyscape.com before submitting the article.

 

if i will add copy past the article then they never quick index...And Not get quick ranking also..please don't mind

 

hey this is very common for blogs and some times even for sites..The main objective of Google is to grab the latest information about different subjects...so it promotes the freshly added content temporarily.After 1 or 2 days Google removes that from top place.

 

hi....
indexing of pages is the property of google...you can not understand it ....google have different algo for indexing...so ....do't worry about it........

 

that true..
dont worry about your index if you dont cheating google..

 

Ya it will be indexed in minutes first by google in blogs through rss feeds chk site:blogname.com and will be indexed in google in 24 hrs . Then will disappear for 2-3 days and will come back to indexed page
