Appears harder to get a page indexed in Bing than in Google

[aristotle]

Last summer I submitted a website to some free directories, and got listings approved in most of them within a short time. Some of these links have subsequently appeared in the external links lists in Google's Webmaster Tools, so I know that Google must have indexed the directory pages that contain the listings.

Today I came across an old list of ten of the directories I submitted to last summer. Out of curiosity, I checked to see how many of the pages containing my site's istings are currently indexed in Bing and Google. To my surprise, I found that Bing hasn't indexed any of them, whereas Google has indexed 9 out of 10.

I also discovered that Google has indexed two wordpress.com blogs I started in 2008 and then abandoned, whereas Bing hasn't indexed either of them.

So out of a total of 12 pages that I checked, Google has indexed 11 of them, but Bing hasn't indexed any.

Of course this isn't a big sample, or a random sample. But it does seem to indicate that Google crawls deeper, and/or has less stringent requirements for what it indexes.

Bing doesn't seem to index anywhere near to as many pages as google.

I was doing some competitive research in my niche, where 1 million pages on a domain is standard. Domains that have high tbPR and a ton of backlinks with a couple of million pages in the google index will have somewhere around 10,000 to 100,000 pages in Bing.

Unfortunately the same holds true for the site i am working on... I have had more success getting Naver, Yandex and Baidu to index compared to bing.

They were building the most enormous datacenter ever. Not sure if it's finished.

But in any event, I wonder if Bing has decided that unless and until a page or site hits a certain threshold, it's not worth displaying in it's results?

I have been able to find some domains with a very large portion of their pages index... that is to say more than 4 million.

What has got them in the index when their model is no different from many other similar websites is beyond me.

Bing has gone on record that they are slow to index new sites and pages.

Bing has gone on record that they are slow to index new sites and pages.

Most of the pages I have been looking at are 3-6 years old...

3-6 years old

doesn't surprise me.

I have a 10+ year old .co.uk site that has backlinks from tens of thousands of pages yet still does not appear in Bing!

And .eu results still do not appear in their United Kingdom results, Show All is fine.
