Q & A

What is the most important part of SEO according to the script?

Technical SEO is considered the most important part of SEO because a single detail wrong can cause the entire website to disappear from Google, even if all other aspects are done right.

What are the three main steps in Google's process for handling web pages?

The three main steps are crawling, indexing, and serving search results. Crawling is when Google finds web pages, indexing is when Google determines the content of the page and adds it to its database, and serving search results is when Google displays the most relevant pages in response to a user's search query.

Why is it a problem if Google can't crawl a web page?

What is the purpose of the indexing process in Google's search engine?

The indexing process involves determining what each page is about, assessing if the page is worth displaying in search results, and then adding the page to the Google index, which is a database of web pages that can be displayed in search results.

Why might Google choose not to index certain pages?

Google might choose not to index pages that are of low quality, duplicates of other pages, or do not contain anything useful, as it aims to provide the most relevant and high-quality results to users.

How does personalization affect search results in Google?

Personalization in Google means that search results can change based on an individual's location, language, device, and even past search behavior, making the ranking of a web page for a keyword an average across all users rather than a single number.

A well-structured website architecture ensures that every page is reachable within three clicks from the home page, making it easier for search engines to crawl and index all pages.

What is the significance of using HTTPS for a website?

Using HTTPS encrypts the data between the user and the site, making it more secure for users and also serving as a ranking factor in Google's search algorithms.
