I just realized that it is not necessary to hijack the back button!
1) Watch out for users coming from Google (or Bing) using the referrer field.
2) Choose randomly In 5% of them are redirect them to your shady domain using a temporal 303 redirect. [If Google notice this, they will hate you.]
3) Host a copy of your competitors page in the shady domain, with all the tracking enabled. [This is illegal! You may get a lawyer C&D, nastygram or more.]
I guess that when the user finds your site in Google and click the link, they will most of the time not be sure of with link they choose, so they will not notice the change. And if they realize that they went to the wrong site, they will click the back button and click the search result again, and get the normal page like the 95% of the people.
This is probably more credible if the search field in the referrer doesn't have your site in it, so the user is looking for any generic site that includes you and your competitors.
As I said before, this is shady and some parts are illegal, so don't do it. Google may demote your site, and also you can get some legal problems.
