Pagination and pagination - what is it?
Pagination (or pagination) consists in dividing the content (article text, product list, blog entries) into individual parts and placing them on subsequent subpages of the website. The use of this solution allows you to improve the website's performance (the subpage from 20 is much faster than 100 images). It is also a nod to the user who can see how many pages he has to review in a given category and can easily remember on which subpage he / she has finished browsing.
Increasingly, on websites, we can encounter infinite scroll paging, which automatically loads the contents of the next subpage when the user scrolls the listing or the content of the article. The only change during browsing will be to change the URL in the browser toolbar. This solution is slightly less user-friendly than standard pagination (the bar with subsequent page numbers), because the person browsing the products does not know which page they are on, so if they leave the website, it will be difficult to return to the same place.
The biggest paging problem - duplication of content
The problem that can occur when pagination is duplication of content. It appears when the same text, the same products, description and title meth tags will be on different subpages. To prevent paging from harming the site's position in the search results, solutions such as:
Rel = "canonical" - canonical URLs
Apply when: You have a page with full content that you are paginating.
Online stores often provide users with the option of browsing all products on one subpage, if they prefer to scroll the content of the page than to glide between subsequent subpages of paging.
Pagination and SEO - how does Google approach paging?
The most popular search engine copes well with paging recognition and in most cases, even if we do not use the above signs, it will recognize the subpages on which the content is divided.
