Being found vs. being sought
There are proven strategies that generic products can use so that they're more likely to be stumbled upon by someone searching. Name your new book with all sorts of keywords in the title, for example, so it organically ranks higher for those very keywords...
The alternative is to create a product that earns a reputation sufficient that people choose to talk about it, choose to argue about it, choose to look for it. Not something like it, but it.
Nice to be found. Essential to be sought.
This was always a good idea, but in a post-search era of mobile and social, it's now the best idea.
