Google ‘Supplemental’ Results No Longer Showing
Google supplemental results set to disappear
The Google ‘Supplemental’ results are already beginning to disappear from many of the data centers and have been absent from the main index results for a while now. To recap on what the Supplemental results were this was an additional index that enabled Google to return results for less popular searches from pages that had a lower PageRank or a more complex URL structure.
Often ‘supplemental’ results would appear only for very niche terms, so using three, four or five search terms or on more abstract queries. These would be marked as Supplemental if you typed in site:wwwyoursite.com into Google.
What is did enable us as to do was to quickly spot pages that in Google’s mind had a lower value. By changing a number of factors, onsite and off, it would be possible to bring these results back into the main index if desired.
However, Google has now decided that over the course of the summer, (whenever that is!) these results will be faded out and integrated back into the main Google index. Since the implementation of ‘Big Daddy’ last year Google is now able to index ‘URLs with more parameters and are continuing to place fewer restrictions on the sites they crawl’.
So the distinction between the main index and the old supplemental index has narrowed and will be gradually phased out. The plus side is that the new index will be deeper and fresher than the old one incorporating supplemental results.
