Why my site is not indexing in google

[Rajesh.Chandran]

In google webmaster i have updated my sitemap in Mar 6th..There is around 22000 links..But google fetched only 5300 links for long time...
I waited for 1 month till no improvement in google index..So apr6th we have uploaded new sitemap (1200 links totally)..,But only 4 links indexed in google ..
why google not indexing my urls? Is this affect our ranking in SERP?

How many links are advisable to submit in sitemap for a website?

Rajesh,

It's not the size of your sitemap because Maximum number of URL on a sitemap is 50,000.  Keep in mind, however, that your sitemap is really just a suggestion tool.  Just because your sitemap contains a URL, doesn't mean Google will crawl it.  The site's architecture and its back links have impact its crawl priority.

1200 is a small amount of 22000 of which 5300 were indexed. its possible that your new 1200 sitemap has links to almost anything but those which are already indexed. As chris has said a sitemap is a suggestion, on big sites google tends to do what it wants to get the data it need.

Hate to say it, but it's not uncommon for pages to not be indexed because they contain thin content.

Take a look at the pages that have been indexed; I'm willing to be that they are a little more fleshed out and rich than those that have not been.

If a given page has only a sentence or two of weak or repetitive content, then it's likely that Google saw it in your sitemap and simply did not think it worthy of indexation.

Also, make sure to test your sitemap and check up on any errors that might have cropped up, that's happened to me quite a few times.

Our site content are unique ...Today i checked GW now 750 links got indexed out of 1300 links..I Couldnt understand the google crawl time & concept..We have waited for 1 month..it crawled only 5300 out of 22000 links....and got 404 error -469 & Not found - 57 errors, day by day the errors getting increase ..after that we redesigned our site model(user friendly) & changed few internal links and created new sitemap & resubmitted in GW last saturday ..Next day it crawled 4 links only ...after 5 days it crawled (today) 750 links..

The error links are changed in new sitemap ..so when will  google crawl links completely & clear all errors..
