Way back in 2009 I used to work for this hotel search engine company where they have this huge database of hotels around the world including the booking prices from different sites where you could book (like Agoda, TripAdvisor, etc.).
I started working there as an internet researcher, I need to search the exact location, facilities, amenities, services, type of rooms, prices, etc. that the hotel offers and input it on the website's database. In this way, the users will be able to know and compare the hotels that they're looking at.
So obviously, I use Google to find the official website of these hotels or at least get the information from people who have been there and tried the hotel. I don't only use Google search, but also Google maps and images to find proof that the hotel exists.
Working for the company for more than a year, and seeing that some of the official websites of hotels are not ranking makes you curious on how search engine works, specifically on my case, how Google works and this is how I think my road to being a SEO specialist started.
Lucky for everyone these days these what we call infographics already exist to help us understand not only through works but also through graphics. So here's an infographic I found only that talks and shows us how Google works, check it out:
