One of the things that can slow-bleed the traffic from your site is the quality (or lack thereof) of the content you publish on your site. Previous Google updates like Panda have already been released specifically to deal with the issue of low-quality content on websites. Long story short: Panda intended to stop sites with bad content from appearing in the search results.
It increases relevancy: Siloing ensures all topically related content is connected, and this in turn drives up relevancy. For example, linking to each of the individual yoga class pages (e.g. Pilates, Yoga RX, etc) from the “Yoga classes” page helps confirm—to both visitors and Google—these pages are in fact different types of yoga classes. Google can then feel more confident ranking these pages for related terms, as it is clearer the pages are relevant to the search query.
That's way easier to do when you understand what all the things you're measuring actually mean. The first place I always start when evaluating a business' marketing is figuring out where the heck all their site traffic, leads, and customers come from. But it occurred to me -- if you don't even know what all those channels mean or how they're bucketed as traffic sources to your website -- it's probably pretty hard for you to start that self-evaluation.

This is the number of views that you can test each month on your website.It's up to you how you choose to use them, either by allocating all the views to one test or to multiple test, either on one page or on multiple pages. If you have selected the 10.000 tested views plan and you run an experiment on your category page which is viewed 7000 times per month, then at the end of the month 7000 is what you'll be counted as tested views quota.
