Ideally you will want to map each page to the most relevant page. Most relevant doesn't always mean identical or even "all that similar" but even the Matt Cutts video on the same topic says get as close as possible.

Sometimes a 301 is done as the brand is changing part of what they do. Again, all you can do if you don't offer a particular service is come close. Think about the user - if you were a wedding, portrait & commercial photographer and you stop doing weddings where would you direct these visitors? Well nothing on the site is going to be completely relevant so ... should you direct them to portraits? Maybe create a new page that says "we no longer shoot weddings but recommend these 4 photographers:" or should you just redirect to homepage?

If your goal is to keep as much of the SEO juice as possible, direct it to the closest page - this maybe homepage or portraits page in the above case. If you want to provide the best user experience, perhaps the "We don't shoot it" page - so it depends on your goals.

Click through rate is an excellent line of thought as well. Nice one. You're 100% right, as well.

These type of links are generally demoted/do not pass juice in the first place.

Matt Cutts said in the past in an interview with Eric Enge:

Matt Cutts: Typically, we want to handle those sorts of links appropriately. A lot of the time, that means that the link is essentially driving people for money, so we usually would not count those as an endorsement.

To me, Shareasale is a huge provider of affiliate links so I would assume Google is well onto those links and doesn't count them. You aren't going to get a ranking benefit from these links, IMO.

Yes, you should be implementing canonical tags back to the main product page.

Also, if your c.50 URLs are parameter based (ie. /product?color=red) than you can also deal with the indexation of those in Search Console. Google gives you the option to set the options for each parameter. (You can also deal with parameters in robots.txt but unless you have to, I would do it through Search Console instead.)

To set them, go to the Parameters page.

For more information, see Google's help page.

I love the way you phrase things. lol

I agree with EGOL here - it's definitely not helpful, it's definitely not needed, it could be harmful, and it's a sign of other potential issues. I would definitely work to remove it from the title.

Plus,
.... I mean what's it trying to accomplish? This tells me it's auto-generated or (stealing EGOL's word) "dumb." because it's a line break. You can't line break a title. I mean I could see some example of code that are meant to do something in a title (for instance, **for bold) but not BR? It makes no sense. **

My strategy has always been to point them at whatever suits your industry (amazon for product reviews, tripadvisor for travel/tourism, Google and Yelp for local biz, WeddingWire for wedding vendors, etc.)  Then make a page on your site that is site.com/reviews and syndicate your reviews to that page.  When someone Googles me + reviews, I want MY site coming up so I can highlight what I want when I want.  It's just good reputation management.  They can still see the rest further down the page but if I can come up #1 for highonseo reviews I sure want to.

This is going to sound like a silly thing to refer you to but I think the problem is (essentially) the same:

How would you do SEO for Anonymous?

Their issue - real news sites won't cover them because of their industry and what they do. Sounds very similar so much of the advice will also work for you.

One of the best answers involved a Moz post and I'd start there:

http://www.seomoz.org/blog/92-ways-to-get-and-maximize-press-coverage

Can you work in easier to link to content such as health topics, etc?  It doesn't matter what industry you are in, there are leaders in it, related niches that can and will help you, and authority sites despite the industry .

Also, you should look into GFY (google: GFY webmaster).  Also search adult backlinks warriorforum and adult backlinks blackhatworld - both return some good results, though nothing I want to link to here.

Finally, do some competitor research.  For NYC escorts, icon companion is a top site. They have a few great backlinks you could take from (open adult directory, etc.)    Once you do a competitor search, you will definitely see some places to get good backlinks and you'll start to see the patterns, as well.

Hope that helps!

Sure, you mostly care about ones that have already jumped up in impressions or clicks, right? I'm going to be very specific on the steps but this isn't as hard as it looks.

1. Go to Traffic Sources > Search Engine Optimization > Queries

2. Select a date range and then use "Compare to" and use "Previous Period."

3. Set Show Rows to 500.

4. Sort the table by Impressions.

5. Copy all the data from the table starting from "1. keyword" and finishing with the end of the table (last change%).  Paste this data directly into Excel. You should have columns A-F used, it'll look very messy.  Something like the attached "sorting1.jpg"

6. Find & Replace "% Change" with "Change"

7. In Column G put this formula:  =IF(LEFT(B1,6)="Change","Yes!","")  Copy this formula from G1 to G2000.  Every line that says "Change" should now say "Yes!" at the end.

8. Copy column G and use "Paste Values" to remove the formula and leave only the "Yes!" in place.

9. To match keywords to their change line, follow this specifically.  In H4, type =B1  This should now say your keyword.  Manually type in a few of these, so go to H8 and insert the formula =B5, then do the same with H12.  The formula is =B9.  You should see three keywords in Column H.

10. Highlight the cells from H1 to H12.  Grab the black square in the bottom right of the border box.  Drag this selection down all the way to H2000.  Copy all your cells from A1 to H2000 and paste values to remove any formulas.  We want just text now.

You should see a list of keywords in column H now, every 4 cells or so.  Check Sorting2 attached.  The rest is very simple.

11. Sort by Column G, Sort by Values, Z to A.  This should be looking valuable now.

12. Delete Rows 501-2000.  All rows should be "Yes!" now.

13. Delete Columns A, B and G.  Feel free to move Column E to Column A if it makes you feel better.

14. Insert a new Row 1 at the very top.  Label each like this:

Cell A1: Impressions

Cell B1: Clicks

Cell C1: Avg Pos.

Cell D1: CTR

Cell E1: Keyword

15. Highlight Row A and push View > Freeze Panes > Freeze Top Row.  Highlight all the data, press Ctrl T to create a Table.  Now you can easily sort any row and sort through your data.  See sorting3.jpg attached.

It's really not as complex as it looks.  Just use the two formulas, follow the steps and boom, sortable and pretty data.

(I may write this up as a YouMoz post with better screenshots, maybe a video tutorial or something, so thanks for giving us the chance to help!)

What you're talking about are called sitelinks.  I found a really good article that explains them here:

http://www.entrepreneur.com/article/235102

The most important bit (for your question) is:

• Sitelinks are automated. There is no Google-given process for creating sitelinks. You don’t get to stipulate what links are featured and when. You can, however, indicate that a sitelink is not important or relevant by demoting it.

That said, lower down the page are some great tips under "Getting Google Sitelinks: A Step-by-Step Guide"

Hope that helps!
