How to find supplemental index ratio?
Recently the technical people of our company were talking about supplemental ratio (almost a new thing for me….though I had this notion that supplement pages are duplicate page.) I was very curious to know what is this supplemental index ratio and how one can find it. I contacted our technical heads to know about it (We surely have smart technical brains to answer almost all the questions)
How to calculate supplemental index ratio?
- Go to google and search for site:yoursite.com , example google.com/search?q=site%3Ameabhi.com .. It says 36 results (This includes all the pages regular and supplemental)
- Now do site:yoursite.com/* example google.com/search?q=site%3Ameabhi.com%2F* (It says 8, this is the regular pages only) OR even you do a search in aol for site:yoursite.com search.aol.com/aol/search?query=site%3Ameabhi.com (It also says 8)
- Now (36-8)/36 = 28/36 = 77% is the supplement index ratio for meabhi.com, which may be quite high.
You can use mapelli.info/tools/supplemental-index-ratio-calculator/?domain=www.meabhi.com (this says 75% but it might be some other datacenter for the total indexed pages as it says index pages = 32 instead of 36)
Supplement pages are not all that bad these days but still you can get a better ratio. Tedster explains what a supplement page is all about.

How to reduce supplement ratio for your site?
I did it as experiment google.com/site:meabhi.com+-site:meabhi.com/* to see the pages that are tagged supplement now I will like to eliminate it one by one. I offered my site to our technical team for experimenting with supplement results as it is quite new. I will post more about the pages that have gone to supplement results.
