I will explore the essential aspects of SEO (Search Engine Optimization) and shed light on the workings of Google Search. SEO focuses on improving your website's visibility in search results. So, let's start by understanding the inner mechanisms of a search engine. Step 1: Crawling: Google engages in crawling to discover new information. Google identifies and adds new sites to its catalogue by following links between websites. For instance, if you have a cupcake-selling website, Google becomes aware of its existence after crawling it. Step 2: Indexing: After discovering your site, Google analyzes its content and organizes it in its vast library of information through indexing. To improve SEO, you can optimize your page content for easier understanding by Google. We'll explore this further in subsequent lessons or refer to the SEO Starter guide. In the case of your cupcake website, Google acknowledges its existence and comprehends the variety of cupcakes you offer, such as gluten-free options. Step 3: Ranking: When users input search queries, Google sifts through its extensive content library to determine the most relevant web pages. To present the most useful results, Google considers factors like the user's location, language, and search terms. This process is known as ranking. For example, if someone searches for "gluten-free cupcakes" from your hometown, your website is more likely to appear in the results. However, someone from a different country may not see your business for the same search. Organic Results vs Ads: As you delve into Search and SEO, you'll encounter the term "organic." Organic search results are presented in order of relevance to the search query and are unaffected by businesses' influence or payment. They differ from paid advertisements, marked as Ads on the search results page. Google's organic search results remain unbiased and unaltered by monetary influence. Take Action: Understanding how Google Search operates empowers you to enhance your website's SEO. Google crawls the web for fresh content, indexes and comprehends that content, and ultimately delivers the most pertinent information to search users. Through the optimization of your content for search engines, you have the opportunity to broaden your reach via Google Search.

Crawling & Indexing:
 Find information by crawling
 Crawler is called “Googlebot.”
 Crawlers look at webpages and follow links on those pages.
 They go from link to link and bring data about those webpages back to Google’s servers.
 The crawl process begins with a list of web addresses from past crawls
and sitemaps provided by website owners.
 Crawlers pays special attention to new sites, changes to existing sites and dead links.
 Organize information by indexing
 Google index includes information about words and their locations.
 When you search, at the most basic level, our algorithms look up your search terms in
the index to find the appropriate pages.
 When you search for “dogs” you don’t want a page with the word “dogs” on it hundreds
of times.
 You probably want pictures, videos or a list of breeds.
***Choice for website owners :- With the robots.txt file, site owners can choose not to be
crawled by Googlebot, or they can provide more specific instructions about how to
process pages on their sites.

4. Algorithms:-
 Algorithms are the computer processes and formulas that take your questions and turn
them into answers.
 Today Google’s algorithms rely on more than 200 unique signals or “clues” that make it
possible to guess what you might really be looking for.
 These signals include things like the terms on websites, the freshness of content, your
region and PageRank.

5. Fighting Spam:-
 Spam sites attempt to game their way to the top of search results through techniques like
repeating keywords over and over, buying links that pass PageRank or putting invisible text on
the screen.
 Google's algorithms can detect the vast majority of spam and demote it automatically.
Types of Spam:-
 Cloaking and/or sneaky redirects
 Hacked site
 Hidden text and/or keyword stuffing
 Parked domains
 Pure spam
 Spammy free hosts and dynamic DNS providers
 Thin content with little or no added value
 Unnatural links from a site
 Unnatural links to a site
 User-generated spam

Title Tag:-
 The title tag defines the title of your web page (or other web document), and is typically the
text that appears as a blue link on search engine results pages.
 Use powerful high CTR keywords & break your SERP.
 Take the time to carefully craft your title tags.
 Several of the words in the title match the user’s query — this causes them to be bolded in
the SERPs.
 Performance Tips:
 As you develop your tags, focus on the following important elements: character
length, word choice, and query match.
 For increased organic clicks, try adjusting your page titles to be more relevant
and/or enticing to click. But do not remove your target keywords as it could impact
your organic ranking.

7. URL:-
 The landing page in the Walmart.com example below leverages
semantic markup for breadcrumb navigation. As a result, the display
URL provides valuable context and additional clickable navigation
options.
Performance Tips:
 When developing your URLs, pay attention to areas such as the folder
structure, word choice, query match, and breadcrumb navigation snippets.
 Ensure your site follows a well-organized folder structure and site hierarchy
that leverages standard navigational tools such as breadcrumbs.
 Be sure to mark up your pages with breadcrumb information for search
engines.

8. Meta Description:-
 Meta descriptions help users understand what your content is about before they see it.
 Meta descriptions as free advertising
 It’s basically an opportunity to get your message out each time your listing is displayed
in the SERPs.
 However, keep in mind that sometimes Google doesn’t display the meta description in a
SERP snippet, and instead uses other sources like publically available data and/or the
content of the page.
