For example, suppose "Running" is my niche, but my site is just dedicated to running on treadmills.
Suppose I have 50 pages, all oriented towards information about running on treadmills.
Then suppose a much larger site that's focused on "Fitness" also has 50 pages that are dedicated to running on treadmills. But that site also has 300 other pages that are dedicated to other fitness topics.
Does Google give weight to my highly focused (just info about running on treadmills) website? Can the smaller but much more focused site get farther with less links than the much more broad "Fitness" site?
