The paging action is to put a piece of content on a different page. Improper use can severely affect the user experience, web development, and search engine optimization (SEO).

This article is the first part of the SEO page optimization guide, and we will discuss the common types of paging that people can find on the web, and list the benefits and drawbacks of using paging.

Paging used on the network

The most common types you can find online are:

List pagination: We use this type of paging functionality to divide rich content into pages.

We found that the product list of E-commerce sites is usually divided into different pages, mainly because they are too many (products), in this case a page is not enough to support, because if you want to display a lot of screen to pull out.

List pagination can refer to: Search engine search results, E-commerce site Product Filter page

We can think of here if you search the word "SEO", Baidu has 82,700,000 related content, put on a page to show, I think you will directly collapse off it.

Content paging: Dividing specific content or articles into several different pages or sections. This type of paging is often used for high flow news portal information class websites.

Content pagination can refer to: Sina, NetEase, the information station of the website. Some information sites are poorly paged. A picture or dozens of words is divided into one page. That's what we'll be talking about later.

Benefits of Paging

Paging is necessary in some cases.

User Experience

When we have a large amount of data on the product, the item does not show all the content, is very correct practice. Through the segmentation of user demand information refinement, to provide a smaller piece of the essence of content, to promote users to browse the content of the page in-depth convenience. You can also ensure that the key components of the user's browsing page are focused and prioritized. (such as the selection of E-commerce products, so that users more accurate to find their own needs as soon as possible goals), with a reduction of user scrolling, click the link.

Load time and server load

Other reasons to use paging include reducing server load. If you put it on a page the user wants to retrieve a product category database at one time 10-50 (1000?10000?) Production, the database will need a certain amount of time to deal with. Page in the display of the time also need to load page elements (js,css, images, etc. caused by the page too large load delay element) This will greatly delay the user demand waiting period.

If paging is used, the database loads the first page element when it handles the top 10 product matching results and quickly gives the user demand results feedback. It may be safe to attract users, stick to him/her, and browse through other requirements.

Advertising revenue

Most news sites sell their main source of revenue, and they want to maximize benefits, and the ability to page through content can help them increase the number of ad spots and the number of ad shows. The use of pagination can increase the number of integrated views of each user's website (this can be understood as the PV of the user). That's why news sites tend not only to separate the contents of the article, but also to split the article itself into different pages.

The drawbacks of paging

Although the benefits of pagination are self-evident, we have to discuss some of the drawbacks of paging that require our attention.

User Experience

Force all content to split several pages forcing users to click on the landing page he needs to load, adding unwanted clicks to the user. In addition, he needs to get all the information the total time will increase (the same content, a single page loading faster than multiple pages load time).

Finally, it is important to note that the current trend is "scrolling instead of paging", and many Internet Content service presentation styles are changing. Like Google image search, Facebook and Twitter now use (AJAX) as an alternative technology. You can enable users to scroll down the page automatically and quickly load additional new content.

Baidu Image Search has also been revised into: search results show the first page content, you slipped to the bottom of the page, a certain amount of time in the loading of new content and show, in the sliding load. You do not need to click on pagination. You can search for a picture to try.

Load time and server load

Experienced programmers, database experts know that paging affects server (host) load reduction is the user access list. In some cases, especially the mass content results paging implementation, can increase the server load! Here I would like to explain: the server in doing content Results page processing need to do some column to match the judgment, paging too much or cause the server to judge the increase n times, plus the mass content of the n multi-user browsing. n more judgments, n multi-user, n multiple pages loaded.

Negative impact on SEO

The disadvantage of paging to SEO is:

1. Increase user's invalid clicks, the page stays time is short, jumps out the rate is high.

2. A large number of duplicate content, page title and URL meaning diversity

3. Page picture Alt attribute determination and add

4. Page core content dependencies and next-page hosting relationship

The combination of reasons will lead to a cable engine crawl included to get a good page pagerank

In addition to the above, pagination leads to decentralized links, anchor text, and PageRank target pages. (Determine the first page? Page two?)

Typically, you would want the user landing page to be on the page "first page" of the page, rather than on the third page of the second page in the middle. The reality is that you may find that some page keywords are ranked well by a page in the page, not the landing page you choose. If these target pages do not meet the user's query needs, this will affect the site's CTR and bounce rate.

Conclusion

Paging is sometimes necessary, but should be used with caution.

In some cases, it can make your content more relevant to the classification of categories without modifying the internal link structure of your site. If the operation is not good to search engine optimization and user experience have serious impact. If the article content is long enough to read, and each section revolves around a core point, can independently support a page content of the case can be considered paging use. Is that too much to say? ><, paging processing if not a lot of background needs to be developed, product managers and programmers do not kill the SEO. )
