Interviews can be a source of some decent traffic, both in giving and hosting them. On the giving side, you’re building your reputation and you’re gaining links, as the places who interview you publish a link to you as their source. On the hosting side, you publish links to influencers you interview, who have a decent chance of linking to you as a “check out this interview I did” comment somewhere. They have an interest in promoting it, after all.
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.
