Question $2$: OK$,$ when I was researching how search engines work, I came across two terms crawling and indexing. I know their basic functions, but how do they interact with each other? How do they aid each other in the process of filtering the search engine results?

Great, but crawling and indexing don't actually work together. Only one is used at a time. When a user uses a search engine, one of two things happen. Either the search engine filters through every page to decide which webpage matches the users' search or$,$ if the program is already familiar with the user's search history, the program searches the user's indexed search history to find a page they have visited in the past that matches their current search.

I$\text{'}$m glad you asked. Crawling and indexing are crucial to each other. Without them working in tandem$,$ search engines don't work. Crawling is the capability of creating a list of content stored online. Indexing is how the program sees what pages are available to search. Together, they find the optimal page for the user based on their search.

That's a great question! Indexing and crawling are two separate programs that, when working together, are able to analyze a website's page and report weaknesses that are visible in the website. Crawling analyzes the coding and indexing analyzes the visual appearance of the website. Together, they provide the website authors with a report containing steps to increase their SEO.
