What Is a URL?
A URL stands for Uniform Resource Locator. It is the complete, standardised address that points to a specific page, image, document, or file on the internet. When you type an address into your browser's address bar, you are entering a URL. Every web page has a unique URL, and they serve two parallel functions: they tell the browser where to find the resource, and they communicate to users and search engines what the page is about.
A URL has several components. The protocol is the first part, typically https://, which specifies the communication method. The domain follows, such as juicydesigns.co.za. After the domain comes the path, which is made up of subfolders and the page name, separated by forward slashes. Some URLs also include a query string, the portion beginning with a question mark that typically passes variables to dynamic pages, such as search results or filter parameters. Finally, a fragment identifier, beginning with a hash symbol, points to a specific section within a page.
From an SEO perspective, URL structure is one of the on-page elements Google uses to understand what a page covers. A URL like juicydesigns.co.za/glossary/url/ is informative and clean. A URL like juicydesigns.co.za/-p=4127 is opaque and provides no information about the page's content. Google's John Mueller has confirmed that descriptive URLs are preferred and that keywords in the URL path carry a small but real relevance signal. Best practice is to keep URLs short, lowercase, hyphen-separated, and free of stop words and special characters.
URL In Practice
The scenario below is an illustrative example, not a Juicy Designs client result. The details indicate the kind of problems that URL hygiene work typically addresses, so treat them as indicative rather than measured.
Imagine a Johannesburg law firm migrating from an old website to a new one. Firms in this position often encounter URL structure problems. The old site might have used dynamic URLs like example.co.za/page-id=37&type=service, while the new site uses clean paths like example.co.za/services/commercial-property/. During migration, every old URL would need to be redirected to its new equivalent using a 301 permanent redirect. Failing to do this would cause Google to treat the new URLs as entirely new pages, losing all the accumulated ranking history of the old pages. URL hygiene is a critical part of any website migration project in South Africa or elsewhere.
For ongoing SEO, South African businesses should audit their URLs regularly. Common problems include URLs containing session IDs that create thousands of near-duplicate pages, capitalised letters that cause duplicate content when the same page is accessed at two different cases, and excessive subfolder depth that buries important pages. Tools like Screaming Frog can crawl a website and produce a complete list of all URLs, making it straightforward to identify and prioritise fixes. Understanding URLs is the foundation of technical SEO and connects directly to how domains, subdomains, and subfolders are structured.
The anatomy of a URL
A URL (Uniform Resource Locator) is the web address that identifies a specific page or resource, and it has recognisable parts. The protocol (such as https) specifies how the browser connects, with https indicating a secure connection. The domain (such as example.co.za) identifies the site, and may include a subdomain. The path (such as /services/seo/) identifies the specific page within the site, often reflecting its place in the site's structure. URLs can also carry parameters after a question mark, used for things like tracking or filtering, and a fragment after a hash that jumps to a section of a page. Understanding these parts helps in structuring a site sensibly and in recognising elements that affect SEO and usability, since a URL is both a technical address and, for readers and search engines, a small signal of what a page contains.
SEO-friendly URLs
A good URL is readable, descriptive and stable, which serves both users and search engines. Readable URLs use real words rather than cryptic IDs, so a person or a search engine can tell what the page is about from the address alone, and including the main term naturally can be a minor helpful signal, though it is not a strong ranking factor. Short, logical URLs that reflect the site's structure are easier to understand, share and link to than long, parameter-laden ones. Consistency matters, using https, a single preferred form (with or without www, with or without a trailing slash) and redirecting the alternatives, avoids duplicate-content confusion. And URLs should be stable, since changing them breaks links and loses accumulated authority unless carefully redirected. Getting URLs right at the outset, clean, descriptive and consistent, avoids problems that are awkward to fix later.
FAQ
Should URLs include keywords for SEO?
Yes, including the target keyword in the URL is a recognised SEO best practice. A URL like mybusiness.co.za/services/seo-pretoria/ tells both Google and the user what the page is about before they even click. Keep URLs short, lowercase, and use hyphens to separate words. Avoid dynamic parameters, random strings of numbers, and stop words like 'and' or 'the' unless they are part of the brand name.
Should URLs end with a trailing slash?
Consistency matters more than which format you choose. Google treats mybusiness.co.za/page/ and mybusiness.co.za/page as different URLs unless you set up a canonical tag or a redirect to consolidate them. Most CMS platforms default to trailing slashes. Pick one format, implement it consistently across the whole site, and set up redirects to enforce it. Inconsistency can create duplicate content issues.
