Website Structure & On-Page Elements
- Meta Tags: Meta tags are bits of code added to your web page’s HTML. They share important details like your page’s title, description, and keywords with search engines and browsers. While visitors don’t see them, meta tags help your site show up correctly in search results.
- Title Tag: Title tags are bits of HTML code that set the main title for your web page, which appears as the clickable headline in search results. When your title tag is clear and relevant, it helps both search engines and visitors quickly understand what your page offers.
- Alt Text (Alternative Text): Alt text, or alternative text, is a short description added to images on your website. It helps search engines and screen readers understand what each image shows. With clear alt text, your visual content becomes accessible and searchable for everyone.
- Header Tags (H1, H2, H3, etc.): Header tags (H1, H2, H3, etc.) are pieces of HTML code that organize your page into sections, showing search engines what’s most important. The H1 tag is the main headline of your page, while H2s and H3s break up the content into smaller topics.
- Canonical Tag: A canonical tag is a bit of code that tells search engines which version of a web page you want to be seen as the “main” one. This helps prevent problems with duplicate content when you have similar pages or URLs. By using canonical tags, you make sure your preferred page gets proper credit in search rankings.
- Schema Markup (Structured Data): Schema markup, or structured data, is code you add to your website to help search engines understand your content. By using schema, you can highlight things like reviews or events.
Technical SEO Glossary
- Robot.txt: Robots.txt is a file you add to your website that gives instructions to search engine bots. It tells them which pages or sections they’re allowed to crawl and which ones to skip.
- XML Sitemap: An XML sitemap is a special file that lists all the important pages on your website, making it easier for search engines to find and understand your content.
- Mobile-First Indexing: Mobile-first indexing means Google mainly looks at the mobile version of your website when deciding how to rank and index your pages. This shift happened as more people started browsing on their phones.
- Page Speed: Page speed is all about how quickly your website loads when someone visits. Fast-loading pages create a better experience for your visitors and keep them engaged. Search engines also favour sites with good page speed, so it can boost your rankings.
- Duplicate Content: Duplicate content happens when very similar or identical information appears on more than one page or URL. This can confuse search engines and cause ranking problems for your site. Using a canonical tag lets you show which page should be counted as the main version, helping prevent these issues.
- Core Web Vitals: Core Web Vitals are important user experience metrics set by Google that focus on how fast your site loads, how quickly it responds, and how stable it looks as it loads. These vitals help measure whether your website feels smooth and reliable for visitors.
Search Engine Operations
- Crawling: Crawling is the process by which search engine bots systematically browse and scan web pages to discover and update content. This is typically the first step and happens after a site is launched or a new page is added or updated.
- Indexing: Indexing is the second step and refers to the process where search engines store and organize content found during crawling, making it eligible to appear in search results.
- Ranking: Ranking is the order in which web pages appear in search engine results, determined by various factors like relevance, authority, and user experience. After a site is crawled and indexed, it will start ranking. The position depends on how well optimized your site is for SEO.
SERP Features & Performance Metrics
- SERP (Search Engine Results Page): The SERP, or Search Engine Results Page, appears after you enter a keyword or question into a search engine. It shows the links and answers related to your query, all in one place. This is where your website can show up when people search for topics you cover.
- Featured Snippet: A summary of an answer pulled from a webpage and displayed at the top of Google’s search results. This is different from the AI overview section.
- CTR (Click-Through Rate): CTR, or Click-Through Rate, is the percentage of people who click on your site’s link after seeing it in search results. A higher CTR means more visitors are choosing your page over others.
- Bounce Rate: Bounce rate is the percentage of visitors who leave a website after viewing only one page, indicating how engaging or relevant the site’s content is.
- Dwell Time: Dwell time is the amount of time a user spends on a webpage after clicking a search result before returning to the search engine results page. This can also be referred to as engagement time or time spent on site.
Content & Keyword Metrics
- Keywords: Keywords are words or phrases that users type into search engines, and that websites target to attract relevant traffic.
- Keyword Difficulty (KD): Keyword Difficulty, or KD, measures how tough it is to rank for a specific keyword in search results. It looks at things like the competition and the strength of other pages already ranking.
- Search Volume (SV): Search Volume is the average number of times a specific keyword or phrase is searched for within a given time frame, usually per month.
- E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness):
E-E-A-T is a set of quality guidelines used by Google to evaluate the credibility and reliability of website content and its creators. It stands for:- Experience: Experience means the content creator has real, firsthand knowledge about the topic.
- Expertise: Expertise is about how much knowledge a content creator shows on a topic.
- Authoritativeness: Authoritativeness means the creator or website is recognized as a trusted source in their field.
- Trustworthiness: the reliability and accuracy of the content, all of which help determine how well a page meets users’ needs and how it may rank in search results.
Off-Page SEO Glossary & Authority
- Backlinks: Backlinks are links from other websites that point to your site, signalling trust and authority to search engines. The more high-quality sites that link to you, the better it is for your rankings.
- Anchor Text: The visible, clickable text in a hyperlink, which helps search engines understand what the linked page is about.
- NoFollow Link: A NoFollow link is a special type of link that tells search engines not to pass any authority to the page it points to. These links don’t boost the destination site’s rankings. They’re often used for sponsored content or in comments to prevent spam.
- NoIndex: NoIndex is a code you add to a web page when you don’t want it to appear in search results. This tells search engines to skip the page when indexing your site. It’s useful for private, duplicate, or unfinished pages.
- Domain Rating: Domain Rating (DR) is a metric that measures the overall strength and authority of a website’s backlink profile, often on a scale from 0 to 100.
SEO and AI Glossary
- AI-Generated Content: AI-generated content is website or marketing copy produced by artificial intelligence tools, which can quickly create articles, product descriptions, and other web content based on input prompts or data.
- Natural Language Processing (NLP): Natural Language Processing is a branch of AI used by search engines to better understand, interpret, and process human language, allowing for more accurate matching of user queries to relevant content.
- Large Language Model (LLM): A Large Language Model is an advanced type of artificial intelligence trained on vast amounts of text data to understand, generate, and manipulate human language. In SEO and digital marketing, LLMs like ChatGPT are used to create content, answer questions, and improve search relevance by simulating human-like writing and comprehension.
- Generative Search: Generative search refers to the use of artificial intelligence models, such as large language models, to generate unique, conversational search results or answers in real time, rather than simply pulling links from an index. This approach allows search engines to provide direct, customized responses to complex queries, often summarizing information from multiple sources.
