As a reminder, supplemental results aren’t something to be afraid of; I’ve got pages from my site in the supplemental results, for example. A complete software rewrite of the infrastructure for supplemental results launched in Summer o’ 2005, and the supplemental results continue to get fresher. Having urls in the supplemental results doesn’t mean that you have some sort of penalty at all; the main determinant of whether a url is in our main web index or in the supplemental index is PageRank. If you used to have pages in our main web index and now they’re in the supplemental results, a good hypothesis is that we might not be counting links to your pages with the same weight as we have in the past. The approach I’d recommend in that case is to use solid white-hat SEO to get high-quality links (e.g. editorially given by other sites on the basis of merit).
( Matt Cutts from google )
If reading posting Matts as a whole and more circumspect, likely non abundant if we of opinion that in the beginning of the year 2007 then Google did refinement algorithm here and there usage solid its the search engine performance.
In general, Google aparts result page to index into two categories.
1. Plays Search Results or result of main index
To locate web pages lionized or has good rangking.
2. Supplemental Results or result of supplement index ( addition)
To locate web pages which, through certain criterion, thought nothing of.
For example: page with conten multiple, page by minimizing incoming links, and others.
Advertisement supposing in radio and television, result of main index is advertisement turned around at displays is main or hour clock beholder solid. On the contrary, result of supplement index is advertisement turned around when displaying poor of beholder. In consequence, pages site is entering very small supplement index possibility that of can seen in every result of seeking.
Like touched by Matt Cutts, the entry of page a situs to supplemental results is not indication is hit by penalti. However, needs soon is observed if when source of main trafik of we are pure come from search engine Google. If when no, its the consequence is of course easy to be guessed: degradation of ranking to site would increasingly sharply followed by degradation of earning also. If front yard a site, which as internal link primary source, has stepped into supplemental results, still relevant of we hope healthy site and always obtains traffic from Google?
Practical way to verify is healthy not its a site in search engine Google is by observing at least three indicators following:
1. Does important pages stepped into plays or supplemental search results. If stepping into supplement page, explains the site has medium of pain.
2. How often Googlebot does crawling. From brief scanning, URL situs emerging in three first pages of seeking of Google is visited by very least Googlebot in tubing 2 week. If when moreover, I of opinion a site fairly not healthy in Googlebot.
3. Happened degradation PR. Degradation of PR as of storey below under value PR before all can be made initial indication that something is not all right with our site. If When its the PR is downwards drastic, of course this site indisposed medium.
Two indicators that is in advance is called as above can be observed by writing down comand site:youdomain.com in search engine Google and observes date of which as described in page result of its the cache. Frequency index done by Googlebot also can be traced by exploiting free account and registers your situs in Google Webmaster Tools.
While to checked pages direct stepping into supplemental results, you can do seeking with the same sintaks is added by comand negative search for text any comprising random letter.
By order of above, you will find a number of URLs property of situs which you targets calibrates text Supplemental Result. Confused unnecessary as far as the URL doesn't refer on page important, like front yard site. Because, teeny possibility that his its all pages an accessible website to result of main seeking. Except mini site of which only had some pages only.
