Auto-generated content: Content that is created programmatically, not written by humans.
Duplicate content: Content that is shared between domains or between multiple pages of a single domain.

Meta descriptions: HTML elements that describe the contents of the page that they’re on. Google sometimes uses these as the description line in search result snippets.
Panda: A Google algorithm update that targeted low-quality content.
Protocol: The “http” or “https” preceding your domain name. This governs how data is relayed between the server and browser.
Redirection: When a URL is moved from one location to another. Most often, redirection is permanent (301 redirect).
Rel=canonical: A tag that allows site owners to tell Google which version of a web page is the original and which are the duplicates.
Scraped content: Taking content from websites that you do not own and republishing it without permission on your own site.
SSL certificate: A “Secure Sockets Layer” is used to encrypt data passed between the web server and browser of the searcher.
Thin content: Content that adds little-to-no value to the visitor.
Thumbnails: Image thumbnails are a smaller version of a larger image.
Title tag: An HTML element that specifies the title of a web page.
Chapter 5: Technical Optimization
AMP: Often described as “diet HTML,” accelerated mobile pages (AMP) are designed to make the viewing experience lightning fast for mobile visitors.
Async: Short for “asynchronous,” async means that the browser doesn’t have to wait for a task to finish before moving onto the next one while assembling your web page.
Browser: A web browser, like Chrome or Firefox, is software that allows you to access information on the web. When you make a request in your browser (ex: “google.com”), you’re instructing your browser to retrieve the resources necessary to render that page on your device.
Bundling: To combine multiple resources into a single resource.
ccTLD: Short for “country code top level domain,” ccTLD refers to domains associated with countries. For example, .ru is the recognized ccTLD for Russia.
Client-side & server-side rendering: Client-side and server-side rendering refer to where the code runs. Client-side means the file is executed in the browser. Server-side means the files are executed at the server and the server sends them to the browser in their fully rendered state.
CSS: A Cascading Style Sheet (CSS) is the code that makes a website look a certain way (ex: fonts and colors).
DNS: A Domain Name Server (DNS) allows domain names (ex: “moz.com”) to be linked to IP addresses (ex: “127.0.0.1”). DNS essentially translates domain names into IP addresses so that browsers can load the page’s resources.
Domain name registrar: A company that manages the reservation of internet domain names. Example: GoDaddy.
Faceted navigation: Often used on e-commerce websites, faceted navigations offer a number of sorting and filtering options to help visitors more easily locate the URL they’re looking for out of a stack of thousands or even millions of URLs. For example, you could sort a clothing page by price: low to high, or filter the page to view only size: small.
Fetch and Render tool: A tool available in Google Search Console that allows you to see a web page how Google sees it.
File compression: The process of encoding information using fewer bits; reducing the size of the file. There are many different compression techniques.
Hreflang: A tag that indicates to Google which language the content is in. This helps Google serve the appropriate language version of your page to people searching in that language.
IP address: An internet protocol (IP) address is a string of numbers that’s unique to each specific website. We assign domain names to IP addresses because they’re easier for humans to remember (ex: “moz.com”) but the internet needs these numbers to find websites.
Lazy loading: A way of deferring the loading of an object until it’s needed. This method is often used to improve page speed.
Minification: To minify something means to remove as many unnecessary characters from the source code as possible without altering functionality. Whereas compression makes something smaller, minification actually removes things.
Mobile-first indexing: Google began progressively moving websites over to mobile first indexing in 2018. This change means that Google crawls and indexes your pages based on their mobile version rather than their desktop version.
Pagination: A website owner can opt to split a page into multiple parts in a sequence, similar to pages in the book. This can be especially helpful on very large pages. The hallmarks of a paginated page are the rel=”next” and rel=”prev” tags, indicating where each page falls in the greater sequence. These tags help Google understand that the pages should have consolidated link properties and that searchers should be sent to the first page in the sequence.
Rendering: The process of a browser turning a website’s code into a viewable page.
Render-blocking scripts: A script that forces your browser to wait to be fetched before the page can be rendered. Render-blocking scripts can add extra round trips before your browser can fully render a page.
Responsive design: Google’s preferred design pattern for mobile-friendly websites, responsive design allows the website to adapt to fit whatever device it’s being viewed on.
Rich snippet: A snippet is the title and description preview that Google and other search engines show of URLs on its results page. A “rich” snippet, therefore, is an enhanced version of the standard snippet. Some rich snippets can be encouraged by the use of structured data markup, like review markup displaying as rating stars next to those URLs in the search results.
Schema.org: Code that “wraps around” elements of your web page to provide additional information about it to the search engine. Data using schema.org is referred to as “structured” as opposed to “unstructured” — in other words, organized rather than unorganized.
SRCSET: Like responsive design for images, SRCSET indicates which version of the image to show for different situations.
Structured Data: Another way to say “organized” data (as opposed to unorganized). Schema.org is a way to structure your data, for example, by labeling it with additional information that helps the search engine understand it.
Chapter 6: Link Building & Establishing Authority
10x content: Coined by Rand Fishkin to describe content that is “10x better” than anything else on the web for that same topic.
Amplification: Sharing or spreading the word about your brand; often used in the context of social media, paid advertisements, and influencer marketing.
Deindexed: When a URL, section of URLs, or an entire domain has been removed from a search engine index. This can happen for a number of reasons, such as when a website receives a manual penalty for violating Google’s quality guidelines.
Directory links: “Directory” in the context of local SEO is an aggregate list of local businesses, usually including each business’s name, address, phone number (NAP) and other information like their website. “Directory” can also refer to a type of unnatural link that violates Google’s guidelines: “low-quality directory or bookmark site links.”
Editorial links: When links are earned naturally and given out of an author’s own volition (rather than paid for or coerced), they are considered editorial.
Follow: The default state of a link, “follow” links pass PageRank.
Google Analytics: A free (with an option to pay for upgraded features) tool that helps website owners get insight into how people are engaging with their website. Some examples of reports you can see in Google Analytics include acquisition reports that show what channels your visitors are coming from, and conversion reports that show the rate at which people are completing goals (ex: form fills) on your website.
Google search operators: Special text that can be appended to your query to further specify what types of results you’re looking for. For example, adding “site:” before a domain name can return a list of all (or many) indexed pages on said domain.
Guest blogging: Often used as a link building strategy, guest blogging involves pitching an article (or idea for an article) to a publication in the hopes that they will feature your content and allow you to include a link back to your website. Just be careful though. Large-scale guest posting campaigns with keyword-rich anchor text links are a violation of Google’s quality guidelines.
Link building: While “building” sounds like this activity involves creating links to your website yourself, link building actually describes the process of earning links to your site for the purpose of building your site’s authority in search engines.
Link exchange: Also known as reciprocal linking, link exchanges involve “you link to me and I’ll link to you” tactics. Excessive link exchanges are a violation of Google’s quality guidelines.
Link Explorer: Moz’s tool for link discovery and analysis.
Link profile: A term used to describe all the inbound links to a select domain, subdomain, or URL.
Linked unstructured citations: References to a business’ complete or partial contact information on a non-directory platform (like online news, blogs, best-of lists, etc.)
MozBar: A plugin available for the Chrome browser that allows you to easily view metrics for the selected page, like DA, PA, title tag, and more.
NoFollow: Links marked up with rel=”nofollow” do not pass PageRank. Google encourages the use of these in some situations, like when a link has been paid for.
PA: Similar to DA, Page Authority (PA) predicts an individual page’s ranking ability.
Purchased links: Exchanging money, or something else of value, for a link. If a link is purchased, it constitutes an advertisement and should be treated with a nofollow tag so that it does not pass PageRank.
Qualified traffic: When traffic is “qualified,” it usually means that the visit is relevant to the intended topic of the page, and therefore the visitor is more likely to find the content useful and convert.
Referral Traffic: Traffic sent to a website from another website. For example, if your website is receiving visits from people clicking on your site from a link on Facebook, Google Analytics will attribute that traffic as “facebook.com / referral” in the Source/Medium report.
Resource pages: Commonly used for the purpose of link building, resource pages typically contain a list of helpful links to other websites. If your business sells email marketing software, for example, you could look up marketing intitle:”resources” and reach out to the owners of said sites to see if they would include a link to your website on their page.
Sentiment: How people feel about your brand.
Spam Score: A Moz metric used to quantify a domain’s relative risk of penalization by using a series of flags that are highly correlated with penalized sites.
Unnatural links: Google describes unnatural links as “creating links that weren’t editorially placed or vouched for by the site’s owner on a page.” This is a violation of their guidelines and could warrant a penalty against the offending website.
Chapter 7: Measuring, Prioritizing, & Executing SEO
API: An application programming interface (API) allows for the creation of applications by accessing the features or data of another service like an operating system or application.
Bounce rate: The percentage of total visits that did not result in a secondary action on your site. For example, if someone visited your home page and then left before viewing any other pages, that would be a bounced session.
Channel: The different vehicles by which you can get attention and acquire traffic, such as organic search and social media.
Click-through rate: The ratio of impressions to clicks on your URLs.
Conversion rate: The ratio of visits to conversions. Conversion rate answers how many of my website visitors are filling out my forms, calling, signing up for my newsletter, etc.?
Qualified lead: If you use your website to encourage potential customers to contact you via phone call or form, a “lead” is every contact you receive. Not all of those leads will become customers, but “qualified” leads are relevant prospects that have a high likelihood of becoming paying customers.
Google Analytics goals: What actions are you hoping people take on your website? Whatever your answer, you can set those up as goals in Google Analytics to track your conversion rate.
Google Tag Manager: A single hub for managing multiple website tracking codes.
Googlebot / Bingbot: How major search engines like Google and Bing crawl the web; their “crawlers” or “spiders.”
Kanban: A scheduling system.
Pages per session: Also referred to as “page depth,” pages per session describes the average number of pages people view of your website in a single session.
Page speed: Page speed is made up of a number of equally important qualities, such as first contentful/meaningful paint and time to interactive.
Pruning: In an SEO context, pruning typically refers to removing low-quality pages in order to increase the quality of the site overall.
Scroll depth: A method of tracking how far visitors are scrolling down your pages.
Scrum board: A method of keeping track of tasks that need to be completed to accomplish a larger goal.
Search traffic: Visits sent to your websites from search engines like Google.
Time on page: The amount of time someone spent on your page before clicking to the next page. Because Google Analytics tracks time on page by when someone clicks your next page, bounced sessions will clock a time on page of 0.
UTM code: An urchin tracking module (UTM) is a simple code that you can append to the end of your URL to track additional details about the click, such as its source, medium, and campaign name.
