Comparison of advantages and disadvantages in website optimization? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

The application of paging on the network

We use this type of paging feature to divide sufficiently rich content into several pages. We find that the product lists of e-commerce sites are usually divided into different pages, mainly because there are too many of them, in which case one page is not enough to support, because if you want to finish the display, you need a lot of screens to open.

1. List paging: we use this type of paging feature to divide sufficiently rich content into several pages.

We find that the product lists of e-commerce sites are usually divided into different pages, mainly because there are too many of them, in which case one page is not enough to support, because if you want to finish the display, you need a lot of screens to open.

List pagination can be referred to: search engine search results, e-commerce website product screening page

We can think here that if you search for the word "SEO", Baidu has 82700000 related content, put it on one page to display, I think you will directly collapse.

2. Content paging: dividing a specific content or article into several different pages or parts. This type of pagination is often used on high-traffic news portal information sites.

Content paging can be referred to: Sina, NetEase, people's Daily online information stations. Some information sites are poorly paged. A picture or dozens of words is divided into a page. This is what we will talk about later.

Advantages of paging

Paging is necessary when there is too much and too much content in a single page of the site, but it is important to note that enough is enough.

1. User experience

When we have a product or item with a large amount of data, it is the right thing not to show all the content. By dividing the refinement of user demand information, a smaller block of essential content is provided, which promotes the depth and convenience of users browsing the content of the page. At the same time, you can also ensure that the important parts of the page browsed by users are focused and prioritized. (such as the screening conditions of e-commerce products, so that users can find their own needs more accurately as quickly as possible), with a link to reduce the number of user scrolls and clicks.

2. Load time and server load

Other reasons for using paging include its ability to reduce server load. If you put it on one page, the user wants to retrieve a product category database 10-50 (1000? 10000? ) per unit yield, at this time, the database needs a certain amount of time to process. The page also needs to be loaded with page elements (js,css, images, etc.) when the page is displayed, which will greatly delay the waiting period of user demand.

If paging is used, the database loads the first page elements when processing the first 10 product matching results and quickly gives users feedback on the results. Maybe security can attract the user, stick to him / her, and browse the results of other requirements.

3. Advertising revenue

Most news websites mainly derive revenue from the sale of advertising space, and they want to maximize profits. The skill of paging content can help them increase the number of advertising space and the number of advertising exhibitions. The use of paging can increase the overall number of page views of each user's website (here it can be understood as the user's pv). This is why news sites tend to separate not only the contents of the articles, but also the articles themselves in different pages.

4. Positive impact on SEO

(1) you can increase the layout of keywords in the page, one more page with the same title, one more being crawled by the search engine and one more likely to be searched by the user.

(2) increase the path for visitors to browse and deepen the depth of visit to the website

(3) due to the increase in the number of pages, the length of stay of visitors in the site is increased, the more time users stay in the site, the longer the stay time will be, and the weight index of the site will be improved accordingly.

The disadvantages of paging

Although the benefits of paging are self-evident, here we have to discuss several disadvantages of paging that we need to pay attention to.

1. User experience

Force all the content into several pages and force the user to click on the landing page that he needs to carry many times to increase the user's useless clicks. In addition, the total time it takes for him to get all the information will increase (the same content, a single page loads faster than multiple pages).

Finally, it is important to note that the current trend is "scrolling instead of paging", and the presentation styles of many Internet content services are changing. Such as Google Image search, Facebook and Twitter now use (AJAX) as an alternative technology. Users can scroll down the page to load more new content automatically and quickly.

Baidu Image search has also been revised recently: the search results show the first page of content, you slide to the bottom of the page, new content is loaded and displayed again within a certain period of time, sliding and loading. There is no need to click paging. You can search for a picture and try it.

2. Load time and server load

Experienced programmers and database experts all know that paging affects the load reduction of the server (host) is the user access list. In some cases, especially the implementation of massive content results paging, can increase the load on the server! Here I roughly explain: the server needs to do some column judgment matching in the content results page processing, too much paging may lead to the increase of server judgment N times, plus N multi-user browsing of massive content. N multi-judgment, N multi-user, N multi-page loading.

3. Negative impact on SEO.

The disadvantages of paging for SEO are:

(1) increase the invalid clicks of users, the page stay time is short, and the bounce rate is high.

(2) A lot of repetitive content, and the page title and URL have various meanings.

(3) determination and addition of ALT attributes of page images

(4) the relationship between the relevance of the core content of the page and the bearing of the next page

Usually, you will want the user landing page to be on the paginated "first page" page, rather than on the second and third page in the middle. The reality is that you may find that some pages with good keyword rankings are one of the pages in the page, not the landing page you chose. If these target ranking pages can not meet the query needs of users, this will affect the click rate and bounce rate of the site.
