I don't need to be convinced but how do you convince others (clients, management) that it is worth spending money on link generating activities. From talking to other in-house SEOs over time I found that they had a similar challenge, so let's talk generally.
Challenges - "I need pictures" - Are there any pictures that show the benefit of links? There is no need to link to such pictures - just describe what they might contain.
- "I need words" - Patents, academic papers, articles (not self-promotional pieces) in respected publications.
- "OK How much do I need to spend?" - How long is a piece of string is not a valid answer. Answers would include various linking strategies and how little/how much each could cost. Articles about % of marketing spend for SEO, esp linking. etc
So there's the challenge.
