Questions for SEO's & Moderators

Hi, I have 4 “hard” questions, at least IMO, here they go, I hope others can learn from these as they aren’t the typical basic questions people ask over and over again.

1) I have a list of articles on my website. I am going to provide other websites in my industry with ONLY the link of the articles. Now I understand about duplicate content, however does Google view just article links pointing to my website as duplicate content? Do I need to give each website a unique title to avoid duplicate content even though they are just articles. The page will look similar to http://www.tm1031exchange.com/articles-on-1031-exchanges.html which is not my website, but you get the point.

2) Using the above link as an example, should I hyperlink the ENTIRE article or is it better only to hyperlink the keywords of the article. Do the backlinks counts just the same when ones keyword is hyperlinked as part of a longer sentence?

3) Additional, does google favor and give good PR to pages only with links as the above link I gave as an example or would it be better to have regular text and only hyperlink part of the title (ie. I would hyperlink just the keyword)
Example: title of article is : Learn how real estate investing can increase your profits. (I would only highlight real estate investing) This way there is lots of normal text and the links are embedded within the a sentence

4) I plan on building an affiliate program for these websites and when they refer visitors that come to my site via these links I’ve mentioned above, will that effect the backlinks? Usually affiliate links look at http://www.hypervre.com/?affiliate=121906 or something like this, can you please explain how I could have code written where I can still track where visitors come from and yet not be detrimental to the quality of the backlink?

Thanks everyone for advice!

1. No [but refer to #2]

2. All link anchors should be different or at the very least widely diverse {no more than 2 or 3 uses for a single aqnchor}

3. PageRank does change but unique titles on each website is better [looks natural] than all the same.

4. you example is ok having multiple params [more than 3] is cutting close to link suicide.

first of all, thanks for your time in responding, if I may, I would like to give a real life example of titles I would display (keep in mind each title would be unique on another website, let me know if you think this is ok

... I would have each sentence with different keywords relating to my keyword which is 1031 exchange, is this ok? I wasn't sure what you meant by "suicide" ? if you could explain what i should avoid i would appreciate it.

you said "no more than 2 or 3 uses for a single anchor", am I safe with my above given example even though I would have the words 1031 almost on every line, but it's used in different contexts with different words and different keyword modifiers

also I wasn't sure if you addressed the question of whether I should hyperlink ENTIRE link or just hyperlink the keyword?

thanks again
