How do we make sense of the statistics?
Not sure what your asking here but I’ll assume you mean what is the difference between visits and visitors. Visits is the number of hits your site receives. Visitors is the unique number of visitors that visit your site.
Is the numbers of visitors are real?
Yes, however determining if a visitor is a person or a bot is more challenging and so we err on the side of caution and unless we can exclude a visitor we count them.
What are typical statistics for a website?/What statistics of a website should have?
No such thing as typical. It is all dependent on your site.
What are good statistics for search engine referrals?
We are dependent on the search engine’s providing the referral information, so the referral information is correct. It may not reflect all referrals by search engines if they don’t provide the referral information to us.
