As dawnsh explained in her reply, the Birth/Marriage/Death records shown in the GRO Indexes each have a volume and page number. You cannot view these certificates.
The only way is to purchase a copy of whichever certificate you want is to order it from the GRO direct (don't order via Ancestry as they charge more) at:
http://www.gro.gov.uk/gro/content/certificates You have to quote when you order all that you have found in whichever index you are looking at i.e. Christian name/s, surname, the relevant quarter i.e. March, June, September or December, year, Volume Number, Page Number. Cost of a certificate is £9.25.
As the titles suggest, the listings are an index only of all registrations held by the GRO (General Register Office).
The only way to find out what is on a certificate is by purchasing it unless you are lucky and the relevant entry appears in online parish records.
Advertising by the major genealogy sites suggest you can find out all you need by subscribing to their sites. However, whilst more and more parish records are slowly being added, their holdings are far from complete and when it comes to the BMD Indexes it is simply that, an index to the GRO indexes and you cannot view certificates in the latter on
any site (unless, in the case of marriages, they have been included in an online parish record). Baptisms in parish records are simply that (not a copy of the birth certificate) and burials likewise (just a record of the burial not what they died from and any other info. that's on the death certificate).
Hope that makes things clearer.
