Francesco Mapelli has launched a new SEO tool called the Supplemental Index Ratio Calculator which allows site owners to check the percentage of pages from their site that are included in the Google Supplemental Index.
Supplemental Index Ratio Calculator uses a normal Google site search (with &filter=0 ) to find how many pages are in the total index (main + supplemental).
Then with it adds the ‘+-inallurl%3Awww.yoursite.com’ extension to find the number of pages in the main index (at the end of this list there’s the “In order to show you the most relevant results, we have omitted some entries …”).
After that Francesco uses some basic math to find out what percentage of pages are in the supplementali ndex.
As you may notice, in the second query there’s a strange operator “inallurl:www.domain.com”. This is not a real google operator, the operator does not exist. It’s just an hack to have google trigger his supplemental filter. You can use “xyz:www.domain.com” and the
results are the same.

99% of my pages are in the supplemental index, according to this tool. I doubt that.

Cool - I talked with Google engineers at SES and they emphatically said supplemental results don’t exist. Actually their exact words were “we took that dog out back and shot it”.
I wonder what they are naming supplemental results now?

Barry Schwartz, this tool works. I’m sure.

If you say so.

Barry, here’s what I’m getting for SERoundtable :
Supplemental Ratio for www.seroundtable.com: 33.83%
* Google has a total of 6680 pages indexed from www.seroundtable.com
* 4420 are in the main index
* 2260 are in the supplemental index

Quote “Then with it adds the ‘+-inallurl%3Awww.yoursite.com’ extension”
there is no search operator called “inallurl”
the search command you might have been thinking of is “inurl”, but when I looked at those differences using inurl, it also wasn’t a difference of “supplimental” results.

I’m not a SEO expert, the tool uses the algorithm exposed at http://www.dailyblogtips.com/calculate-your-google-supplemental-index-ratio/ , other queries (like site:www.mapelli.info *** -sljktf ) can give different results… It’s a matter of trusting one query or the other, I think.
Also, regarding the inallurl: thing…

The tool did not provide accurate results for me.

If the tool is using “Omitted Results” to flag Supplemental Results then it’s completely useless. Matt Cutts has already confirmed that “Omitted Results” are often not Supplemental.
Usually, they are just pages with identical or near-identical page titles and/or meta descriptions that have been filtered as “duplicate content”.

guys,
thanks for your feedback.
You were probably all right:
the tool didn’t force the omitted results to be included in the search for the pages in the main index, so sometimes just a couple of results were returned for some sites (e.g. seroundtable).
Now the tool has been updated and forces the omitted results to be included with &filter=0… It should return better results.
Please tell me how it works for you.
Thanks

My question is what the percentage of supplemental pages means? I found many sites with good SERP have over 75% supplemental contents.
Andy Beard on Sep 13, 2007 at 6:59 am
Here is a fun result
-1.68%
Yes that was a negative percentage ;)
francesco mapelli on Sep 13, 2007 at 7:48 am
that’s due to the approx number of results provided by google…
I’ll fix it asap… :)
Andy Beard on Sep 13, 2007 at 7:55 am
Based upon the /* method I currently only have 20% supplemental
Most of those are fairly isolated duplicate content pages.
I need to encourage Google to index my translated pages to get back up to 20,000 pages indexed and not just 1800

I was checking the top ten for the calling cards search and many of them are over 80%, some even over 90%…
I’m not sure if you can trust those results, how can you be in the top 10 for several keywords if 80% of your site is in the supplemental results?
