Welcome to the Q&A Forum

I would create a generic canonical "/tickets/liverpool_arsenal" which lists the upcoming games. I would create unique canonicals/titles with event information for each game. Use a 302 to redirect to the most appropriate content (i.e. the upcoming game).

Yes, there may be some tricky JS that can fool them, but they have got very good at it. I should add, every link leaks link juice, even if the result is that the linked page does not recive it, such as a no-follow or a JS link that is broken or appears broken to the SE

I wouldn't consider this as an SEO decision, but a human decision. Is this the best method for your users? Is this the most efficient way for them to be able to perform this particular action? Any negativity is going to affect your users more than it will your SEO I believe in this case. As to Google bots seeing the pop-up, a general rule I use is if you can see it in the source code of your site, Google can, too.

Again, not totally clear cut. Depends if the links are within the content, site wide, above or below an affiliate link, withing one or several pages. I would err on the side of assuming that if there's affiliate and non-affiliate links then the clean links won't count for as much.

I doubt you will ever find any decent resource in English about doing SEO in Russia. At least I've never seen one. Normally, a big part of the content on such a resource is user-contributed (like here on SEOMoz), and there's no reason for Russian users and seo-marketers to use English when they can write in their native language. Paid links are very popular in Russia. Buying and selling goes through www.sape.ru. This is a link exchange which is far more superior than its analogues in the English-speaking world. I've never done SEO in Russia (being a native Russian) but I know for sure that without paid links you will hardly get into the top-10 in Yandex. Especially if you sell on a competitive market. Disclaimer: I'm not a big fan of paid linking. Just reporting the things how they are in Russia. There are fiercely competitive markets, such as travelling, where you can consider yourself lucky if your travel agency gets into the third page of SERP even if you buy links on SAPE

There's also this great video from SEOmoz - http://www.seomoz.org/blog/smarter-internal-linking-whiteboard-friday.

Don't redirect, create a sub folder for English content.

You could tell which company? And what keywords would like to optimize the off-page?

Hey Jorgediaz, first off I think it would be wise to add the canonical tags specifying the primary URL for all of your pages, additionally it wouldn't hurt to add the parameter in question to your Google webmasters tool letting Google know to ignore your affiliate parameters.  You can find that in the Site Configuration settings under the 'parameter handling' tab. I personally woudln't worry too much about the 'loss of link juice' since I think what Matt Cutts is talking about is more duplicate content that results from shopping carts that might serve up a very similar page based on a filter (such as re-ordering products by price).  In my experience affiliate links aren't the greatest in the first place, many are probably even using your publisher ID sending the link to an intermediary source for tracking purposes, so to recap, if it were me I'd add the canonical, add the parameter in your webmaster tools and leave it at that. Hope this helps.

Thanks!
