Next, we calculate the startIndex, which is the first item that should be displayed on the current page by multiplying the page parameter with the itemsPerPage. We also calculate the endIndex that comes immediately after the last item that should be displayed on the current page. Once you’ve selected the most appropriate UX strategy for your site and SEO, make sure the Google crawler can find all of your content.

- This includes coverage of software management systems and project management (PM) software – all aimed at helping to shorten the software development lifecycle (SDL).
- Beyond just segmenting data, pagination also enhances the user experience and ensures that your API is efficient.
- I’ve thought long and hard about this and finally ended up with the solution I’ll describe below.
- Thin content could also result from a page with little content, and scraped and spinner content too.
- Cursor-based pagination excels in efficiently navigating through vast data sets.
We’ll look at different pagination styles, the backend implementation, and recommended tools, methods, and best practices. Provide metadata in the API responses to convey additional information about the pagination. pagination in web application This can include the total number of records, the current page, the number of pages, and links to the next and previous pages. This metadata helps API consumers navigate through the paginated data more effectively.

Before we look at how to properly implement pagination on your site, we need to pause and consider the effects of Google’s announcements. When sites with high site authority link to your site, it is an indicator that your site is also high authority. In the Oscar Hunt example above, all the items shown in the image belong to one product category.
The main point is in the exclusion of all pages of pagination from the index, except the first. For this solution, you’ll be adding a meta tag to the section of paginated pages. I think currently your api’s actually responding the way it should. The first 100 records on the page in the overall order of objects you are maintaining. Your explanation tells that you are using some kind of ordering ids to define the order of your objects for pagination.
Developer Portals Need to Be Unique to Stand Out
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. You’ve probably come across endless scrolling of goods on e-commerce sites, where the products are constantly downloaded when scrolling to the bottom of the screen. Although this is an excellent opportunity to improve usability, this method has to be used correctly. It is desirable that the products are not automatically loaded when scrolling.
Pagination has but one good cause – performance protection, and is at the cost of data assurance of completeness. Your server is responsible to return the id’s of deleted records which is deleted after the last_request_time as well as return the updated record after last_request_time between “id1” and “id10” . Just a note, only using one timestamp relies on an implicit ‘limit’ in your results. You may want to add an explicit limit or also use an until property. The returned cursor, def456, can then be used to retrieve the next set of results. API pagination is essential if you’re dealing with a lot of data and endpoints.
Pagination for section elements
In addition to this, you will often find out that you have the same SEO title and meta description tags on multiple pages of your site. In this case, duplicate content on website can cause difficulties for search engines when it’s time to determine the most relevant pages for a particular search query. Cursor-based pagination excels in efficiently navigating through vast data sets. The way it works is that the API provides a “cursor”—similar to a bookmark—which marks a specific item in the data set.
In this article, I have discussed different methodologies in implementing pagination links in a web application. I have covered the database-driven approach, the middle-tier approach, and some third-party solutions. I have also detailed the actual algorithm for the page links generation. Ultimately, which solution you chose will depend on the size of the dataset, technology at hand, size of the site, and the budget for the project.

How can API pagination help your APIs function at peak performance? As consumer expectations ramp up, API performance has never been more important than it is today. It’s a well-known statistic that 53% of web users will abandon a web page if it takes more than 3 seconds to load. If the button’s index doesn’t match the current page, the active class is removed. The updateActiveButtonStates() function then goes through each of these buttons one by one, using a forEach loop, and compares its index with the value of the currentPage variable. We append our button container to the end of our .content wrapper, and then place our buttons inside the button container.
All the heavy lifting is done on the database tier and the requester of the result set only gets a portion of it. One notable advantage of page-based pagination is its predictability. It effectively eliminates the chances of navigating to nonexistent pages—a common pitfall in offset pagination. After choosing the best approach to retrieve the result set and traverse it, the application needs to create the actual page links for users to click. Below is a generic function pseudo-code, which should work with any server-side technology.
The last line uses the getElementsByTagName method to select all the elements with a tag within the table. We create an array (items) of all the child elements and used the slice(1) to exclude the first row (header) and create an array of the remaining rows. In this example, we wrap the logic of the /products endpoint in a try-except block. If any error occurs during the execution, we catch it and return a JSON response with an error message and an appropriate status code (400 for client errors). Account for edge cases such as reaching the end of the dataset, handling invalid or out-of-range page requests, and gracefully handling errors.
I’m an experimentalist, researcher, recording every step of how to rank number 1. Here to help, verify, explain, cross-examine the wonders of search engine. This article by Google explains how to go about making a page canonical among other pages with duplicate content. Ideally, depending on the number of products that you have, you would want to split them into categories if you have multiple products. You then need to put the canonical tag on all the pages where the pagination landing page redirects to.
It also features consistent ordering, even when new items are added to the database. Offset pagination is popular with apps powered by SQL databases, as limit and offset are already included with the SQL SELECT library. For example, you can implement pagination using links to new pages on your ecommerce site, or using JavaScript to update the current page.
