Gradual decline in Google indexing for my site

[NoahSEO]

For the past month, my site's google indexing number suffering a drop from 1800 to 1250. I used site: search operator to check this, and the outcome number seems like dropping everyday, it's like a trend, that why I take it very serious.

I upload the sitemap in WMT, but it doesnt work. Why there is a declining, and how can I get rid of it? I need help, thanks in advance:)

First, I've uploaded many sitemaps into WMT, and they've all passed muster by Google's standards. You might try using a different sitemap generator.

Second, Google tends to index more pages of a site if that site is more popular. So I imagine it's not at all uncommon for Google to index fewer pages of a site if it deems appropriate.

Assuming everything else is normal with your website, I can only suggest focusing on publishing more useful content, and networking with other publishers in your niche to get more inbound links.

In addition, I'd say use a metric like indexed pages as only a secondary indicator of your site's health. Instead, I recommend making the primary Google SEO metrics center on actual search traffic - which URLs get it and on which keywords.

Even further than that, I'd add in how much of that traffic is a conversion and even watch the dollar value of each conversion. Indexed pages cannot be deposited into your bank account.

@Steven, yeah, today, I regenerate a sitemap for my site, and i saw the sitemap page number scale over 9000, that's a lot increase in contrast to before, and after upload this sitemap, i found the index number increase.Truely, that works!

@tedster, Monitoring the indexing number over the sites is kind of our trandition, we take the outcome figures as indicator, we rely much on SE, so we take those things very serious.

Thanks for both of you for the quick answer and input, I think tedster is definitely right, conversion is what we should work even harder on :)

we take the outcome figures as indicator

Ok - but you need to acknowledge that it is a very fuzzy indicator, Google's data gets buggy over extended periods, and it even varies across data centers.

I've seen websites apparently drop from 85% indexed to under 50% indexed and get MORE search traffic and higher conversions from that traffic.

I agree, tedster. Sometimes the site: search results number fluctuates in a very strange way.
