#No.1 Pagination: Best Practices for SEO & User Experience
Sure, we have to make clear the reasons:

Why is Pagination an SEO Issue?
Pagination, the practice of segmenting links to content on multiple pages, affects two critical elements of search engine accessibility.

* Crawl Depth: Best practices demand that the search engine spiders reach content-rich pages in as few “clicks” as possible (turns out, users like this, too). This also impacts calculations like Google’s PageRank (or Bing’s StaticRank), which determine the raw popularity of a URL and are an element of the overall algorithmic ranking system.
* Duplicate Content: Search engines take duplication very seriously and attempt to show only a single URL that contains any given piece of content. When pagination is implemented improperly, it can cause duplicate content problems, both for individual articles and the landing pages that allow browsing access to them.

And, I do noticed the dos & donts
Do:

* Try to link to as many pages of the pagination structure as possible without breaking the 100(ish) links per page limit
* Show newer content at the top of the results list when possible, as this means the most link juice will flow to newer articles that need it (and are temporally relevant)
* Use and link to relevant/related categories & subcategories to help keep link juice flowing throughout the site
* Link back to the top results from each of the paginated URLs

Don’t:

* Show only a few surrounding paginated links from paginated URLs – you want the engines to be able to crawl deeper from inside the structure
* Link to only the pages at the front and end of the paginated listings; this will flow all the juice to the start and end of results, ingoring the middle
* Try to randomize the paginated results shown in an effort to distribute link juice; you want a static site architecture the engines can crawl
* Try to use AJAX to get deeper in the results sets – engines follow small snippets of Javascript (sometimes), but they’re not at a point where this is an SEO best practice
* Go over the top trying to get every paginated result linked-to, as this can appear both spammy and unusably ugly

Last, you have to pay attention to Nofollows. Rel=Canonicals and Conditional Redirects.

#No.2 Strategic Link Building: How to Productize Link Acquisition and Dominate Your Niche

In the deck below, I walk through a number of examples of sites, primarily startups, that have done this. These include:

* Twitter – every user of Twitter has an incentive to link to their profile so more people will follow them. This is also true of sites like Facebook, LinkedIn, DeviantArt, Etsy & others
* Vimeo – nearly everyone who uses Vimeo appreciates the beautiful aesthetic they’ve created. The embeddable versions of Vimeo videos look and feel more professional and high quality than nearly any other player, hence they get embedded (a lot). This embed action automatically drives links back to the video on Vimeo’s site, Vimeo’s homepage and the user’s profile, all with targeted anchor text.
* Urbanspoon – not only do they give badges to restaurants like Yelp and have started an online reservations system like OpenTable, Urbanspoon also features reviews from bloggers and foodies, who are then incentivized to promote their inclusion on the site.
* Last.fm – the widgets users embed on their site to share their favorite music automatically creates links back to the service.
* SurveyMonkey – a truly viral product (anyone who’s surveyed is automatically exposed to the site), SurveyMonkey is inherently link acquisitive through the product. In order to use the service, you need to link to SurveyMonkey’s site, where your form is hosted.
* Scribd – just look at the embed and the link below; ’nuff said.
* Miibeian.gov.cn – possibly the greatest link building strategy ever devised. The Chinese government requires that all websites in the country link to this site in order to operate legally; not too shabby, eh?
