HTML validation fails as I am not using '&' instead of '&', and I am keen to correct this.
However, if I go ahead and fix these querystrings would it cause any problems with currently indexed pages? Would I suffer duplicate content due to having to differing URL's in the index:
Thanks, in advance.
The first search returns zero results. The second search returns 672 million results, and every one of them has & in the uri, despite the fact that an explicit search generates zero results. So it looks to me that Google is right on top of this, and the two versions of the uri are clearly not seen as duplicates. Rather, everything seems to be mapped to the & version.
Naturally I was nervous when going ahead and changing all the links to & today.
I can only cross my fingers and hope.
Does anyone else have any experience or thoughts about this?
Look in your raw log files and see that even though the link has & in it, that the browser requests a URL as if it just has a & when the request hits the server.
