The first line creates an event listener that ensures that the JavaScript code runs after the HTML content has been fully loaded and parsed. This is to prevent any manipulation or interaction with elements before the content becomes available in the DOM. In this method, as users scroll or click a “Show More” button, more content is loaded dynamically. In conclusion, while implementing pagination alone can significantly enhance site navigation and user experience, it’s crucial to be attentive to user needs and preferences. Regularly collecting feedback and analyzing user behavior can help refine and optimize the pagination strategy for better user experience. You want to avoid using first and last buttons when this kind of structure doesn’t exist, which could lead to users navigating unnecessarily.
Sometimes pagination design patterns are visible, like the examples above, but other times it’s invisible like the infinite scroll patterns often found in social media feeds. Pagination is a design pattern used to divide content into separate pages. Reviewing paginated content can improve your site’s user experience. These types of URLs help Google understand the relationship between each page. Plus, they make it easy for users to quickly identify where they are on your website.
Designing APIs for Pagination
The API consumer includes the cursor value in subsequent requests to fetch the next page of data. Since page and limit are being used as query parameters, let’s continue using those. When you need to request information, you’re going to simply add a REQUEST pagination in web application $request argument to the controller. A cursor is a piece of data that points to an element with the info to retrieve the previous and next items. With cursor API pagination, the server will usually return the element to retrieve the next page.
We also calculate the endIndex that comes immediately after the last item that should be displayed on the current page. Since the implementation is rather complicated, you should be very careful when applying this method. In most cases, this method is a priority and can be implemented fast.

It also features consistent ordering, even when new items are added to the database. Keyset-based API pagination is when an API provides a key parameter that delineates the query results. One example is if an API is sorted by ID, one key parameter could be since_id. Some other possibilities could include since_updated_at or since_created_at. When building customer-facing integrations (i.e. product integrations), you’ll be dealing with a diverse set of 3rd-party APIs that use different types of pagination. This can make your integration development process all the more complicated and time consuming.
More specifically, it allows you to specify the page number and the page size (limit). From there, the server can calculate the offset and return a page with items that match the page size. When you use a self-referencing canonical tag on paginated pages, you’re telling search engines that the content on each paginated page is the “primary” version of the page.
Use unique URL for each page
A forward cursor allows you to retrieve the next set of records, while a backward cursor allows you to navigate back to previous records. While it provides bidirectional navigation, cursor-based pagination offers limited flexibility as the client can’t easily jump to a specific page. Keyset pagination, or the seek method, is tailored for scenarios that involve large or frequently-updated data sets. It involves using a specific field (or set of fields) as a key to paginate through the data set. This key is usually a unique and sequentially ordered column—for example, a timestamp or an auto-incrementing ID. Page-based navigation divides data into uniformly sized pages, simplifying data handling and enhancing the developer experience.
- For example, say your ecommerce shop has a “View all” button along with paginated archives.
- This throws off your whole search, and you will miss one item.
- Let’s conclude with a real-world example to help you work pagination into your own API design.
And navigate to other pages within your pagination as needed. One purpose of pagination is to help users navigate your site. But if pagination isn’t set up correctly, users might actually be less likely to click through each page.
Use Parameter URLs for the Paginated Pages
When your site has large amounts of data, search engine bots need to use their crawl budget wisely. This means that there is a likelihood that some of your content will neither be crawled nor indexed. When implementing pagination, there are several common SEO mistakes that can cause issues with search engines.
This is important because AJAX pagination often loads new content dynamically, which can be difficult for search engine bots to crawl and index. Load More is another type of pagination that displays additional content when users click on a “load more” button. This type of pagination can be used to display a continuous stream of content without requiring users to navigate to a new page. As users reach the end of the content, new items are dynamically added to the page.
Provide sorting and filtering parameters to allow API consumers to specify the order and subset of data they require. This enhances flexibility and enables users to retrieve targeted results efficiently. Determining an appropriate page size for a paginated API involves considering various factors, such as the nature of the data, performance considerations, and user experience. Select an optimal page size that balances the amount of data returned per page. A smaller page size reduces the response payload and improves performance, while a larger page size reduces the number of requests required.
For example, we have a category with sneakers, and we want to create landing pages for search deliveries with different brands, using parameters in the URL. However, poorly designed pagination can disrupt the user experience. If page numbers are too close together or if there’s no clear way to move to the next chunk of content, users can become frustrated.
It helps capture any changes in employee status, designation, HR policies, etc. across different applications a business uses. Offset pagination has its limitations, however, such as the limitations of large offset values and inaccuracies that come from page drift. Keyset pagination is a bit more robust, but it’s also tightly tied to page results. Seek pagination is even more robust, as it returns consistent ordering even when new items are added to the table. Seek pagination can be more complicated for the backend to implement, however.
