Nick - Sorry if there's a misinterpretation. As I read it now, I can see where I might have misread it, but I'm still not completely clear about what you're saying, and there are several possible scenarios....
I haven't disabled any back button?
I said that the flash interface has a back button which loads up the page which has low quality links pointing to it meaning i can't remove this page.
To me, this sounded like...
a) the back button isn't performing as expected...
b) and that the target page for all the bad external backlinks coming in is reloaded by a Flash interface when "a back button" is used.
In light of your clarification, I take it that this isn't the
back button... ie, it's not the main back button for the browser, but it's a
separate back button built into a "Flash interface".
The extent of the interface isn't clear, but it will make a difference to your situation.
I've run into two kinds of Flash interfaces, both a disaster for SEO. One, just Flash nav links for a site essentially built in html, with various Flash embellishments. Flash links can't be crawled, but they look fancy. Each html page does have its own url. The last time I encountered a developer doing this was in 2007. It's a dated approach.
The other scenario, much worse, is that the bulk of the site is a "Flash movie", as I think they were called, with the entire "movie" (consisting of many so-called "pages") all defaulting to only one url... essentially search engine invisible except for html text within the default html page.
Since you described the setup as having "a back button which loads up the page which has low quality links pointing to it"
, I had read it to mean that it was always reloading a particular html page... ie, the one
page with links on it. not a Flash sequence. And since it was always the page with links on it, the Flash back button sounded like a trick to keep you stuck on the targeted page. Thus, my possible misinterpretation.
More to follow on your question, but first please advise whether the links page you're describing...
i) is a single html page in an html site with Flash embellishment...
ii) or part of a Flash movie sequence (that's embedded in a single html page and addressed by a single url)...
iii) and, if (ii), whether the entire site is a Flash movie, or whether part of it a Flash movie and part is individual html pages
As adder says, you do want to get rid of the Flash, but if the entire site is a Flash movie and you 410 the default url for it, you may essentially be removing all inbound link juice to the site.
