Hello everyone,
I got this question in an interview and was stuck on how to solve it
How would you approach this problem?
How many active internet website there is on internet?
Hi, thanks for your question. I think the case is essentially testing your ability to segment a massive concept like 'internet websites' to its components. Below is my answer for this case:
Assume one website represents one particular entity (e.g. LinkedIn is one website and not multiple web pages)
No. of active internet website = [No. of government websites (e.g. US Department of Justice, Ukraine's Telecommunications Commission etc.) + No. of Private Sector websites (e.g. Facebook, McKinsey, UBER etc.) + No. of NGO websites (e.g. Oxfam, Red Cross etc.)] x 1.1 (10% for others that don't fall into this category like random personal websites you're developing out of interest, school work, pilot project etc.)
No. of government websites = No. of countries x Average no. of industries per country
No. of Private Sector websites = Average no. of companies x No. of industries
- If more detail is required, average no. of companies can be broken down to family businesses, SMEs, and large corporations. I would advise you to size based on a medium-sized country and just use that to multiply by the total number of countries
No. of NGO websites - Similar as No. of Private Sector websites
Hope this helps in any way and happy to get comments/feedback on this - thanks!

Hi,
I would try this:
- 1M words in English language
- 60% or 600k are nouns
- 1.2 M if every word has multiple forms (e.g. dog / dogs)
- How often do I see a single-word web-sites? Probably 1 in 50
- How many domain zones? .com is probably 60% of the internet
You can take it from here and add as many assumptions as you want (e.g. different languages, word permutations, etc). I think this case is more about the approach rather than having precise numbers.
