Alt Text

Alt text (alternative text) is a description added to an HTML image tag that tells search engines and screen readers what the image depicts. It's important for image SEO and web accessibility. Good alt text is descriptive, concise, and includes relevant keywords naturally.

Backlink

A backlink is a hyperlink from one website to another. Backlinks are one of Google's most important ranking factors because they act as "votes of confidence" from other sites. The quality and relevance of backlinks matter more than quantity — one link from a high-authority site is worth more than hundreds from low-quality sites.

Bounce Rate

Bounce rate is the percentage of visitors who leave your website after viewing only one page without taking any further action. A high bounce rate may indicate that your content doesn't match search intent, your page loads too slowly, or your user experience needs improvement.

Canonical URL

A canonical URL is the preferred version of a webpage when multiple URLs contain similar or identical content. The tag tells search engines which version to index and rank, preventing duplicate content issues that can dilute your page's ranking power.

Click-Through Rate (CTR)

CTR is the percentage of people who click on your link after seeing it in search results. It's calculated as clicks divided by impressions. A higher CTR indicates that your title tag and meta description are compelling. CTR is influenced by your ranking position, title wording, and presence of rich snippets.

Content Gap

A content gap is a topic or keyword that your competitors rank for but you don't. Identifying content gaps reveals opportunities to create new content that can capture search traffic your site is currently missing. Content gap analysis is a key strategy for competitive SEO.

Core Web Vitals

Core Web Vitals are a set of Google metrics measuring real-world user experience: Largest Contentful Paint (loading speed), Interaction to Next Paint (interactivity), and Cumulative Layout Shift (visual stability). They are confirmed Google ranking factors and can be checked in Google Search Console.

CPC (Cost Per Click)

CPC is the average amount advertisers pay for a single click on a paid search ad for a specific keyword. In SEO, CPC data helps estimate the commercial value of organic traffic — keywords with high CPC are typically more valuable to rank for because they indicate strong buyer intent.

Crawl Budget

Crawl budget is the number of pages a search engine will crawl on your site within a given time period. For large websites, optimizing crawl budget (via robots.txt, internal linking, and removing low-value pages) ensures that your most important pages get crawled and indexed regularly.

Domain Authority

Domain Authority (DA) is a score developed by Moz that predicts how likely a website is to rank in search results. It ranges from 1 to 100, with higher scores indicating greater ranking potential. While not a Google ranking factor itself, DA is a useful proxy for a site's overall SEO strength.

E-E-A-T

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It's a framework Google uses in its Search Quality Rater Guidelines to evaluate content quality. Pages demonstrating first-hand experience, subject matter expertise, authority in the field, and trustworthiness are more likely to rank well, especially for YMYL (Your Money or Your Life) topics.

Featured Snippet

A featured snippet is a special search result that appears at the top of Google's organic results (position zero). It displays a direct answer extracted from a webpage, along with the page title and URL. Earning featured snippets can dramatically increase your visibility and click-through rate.

Google Algorithm Update

A Google algorithm update is a change to Google's search ranking systems that can affect how websites are ranked in search results. Major updates (like core updates, helpful content updates, and spam updates) are announced by Google and can cause significant ranking fluctuations. Staying informed about updates helps you adapt your SEO strategy proactively.

H1 Tag

The H1 tag is the main heading of a webpage, defined in HTML as

. It should describe the page's primary topic and typically contains the target keyword. Best practice is to have exactly one H1 per page, making it distinct from H2-H6 subheadings that organize the content hierarchy.

Impressions

In SEO, an impression occurs every time your URL appears in search results, regardless of whether the user clicks on it. Tracking impressions in Google Search Console helps you understand your visibility for specific queries and identify opportunities where you appear but don't get clicks.

Internal Linking

Internal linking is the practice of linking one page of your website to another page on the same website. Internal links help search engines discover and understand the structure of your site, distribute link equity (ranking power) across pages, and guide users to related content.

Indexing

Indexing is the process by which search engines store and organize web pages in their database (index) so they can be returned in search results. A page must be crawled and then indexed before it can appear in Google. You can check your site's indexing status in Google Search Console under the "Pages" report.

JSON-LD

JSON-LD (JavaScript Object Notation for Linked Data) is Google's preferred format for implementing structured data (schema markup) on web pages. It's added as a
