How can website maintenance and optimization deal with the problem of index volume reduction?

First, the index number of websites refers to the number of websites captured. Generally speaking, there are two main factors that affect the decline of website index.

1. Dead link of website

If there are a lot of dead links on the website, the spider will not be able to crawl, which will result in zero index of the website. At present, the best solution is to check the website regularly to avoid dead links on the website.

2. Quality of articles

The quality of articles on a website affects the number of indexes on the website. If a website does not rank, this means that Baidu Spider does not visit the website frequently, resulting in zero index number of the website.

The best way to solve this problem is to improve Website construction The quality of the last article. As long as the article quality improves, the number of indexes on the website will also increase.

How should we deal with the sharp decline of website index?

1. Timely deal with dead chain problems

When there are dead links on the website, they should be solved in a timely manner, submitted to the search engine or the corresponding links for timely processing, or jump, set 404 pages, etc.

2. Do a good job of website content

Only websites with excellent content can attract users and spiders to crawl. Only well written content can be included. Baidu search engine likes original and high-quality articles very much.

Good website content will never be outdated, because high-quality content is the continuous driving force of website development, and high-quality content is also the best way to constantly focus on the website to attract new users, retain old users, and maintain user loyalty.

Generally speaking, high-quality articles are very beneficial to user experience in terms of content and layout. Generally speaking, the content you like is either useful to users, can resonate with users, or is very interesting.

3. Look for high-quality external chains

With the update of Baidu algorithm, external links play a smaller and smaller role in search engines. However, building high-quality external links will increase the frequency of spiders crawling to websites. We establish high-quality external links so that spiders can access the website from multiple channels to grab new pages, or we hope Baidu will voluntarily submit these external links.

In fact, when Baidu updates its website, it will also cause instability of the website, especially every major update of the search engine, so Baidu's update will also lead to a sharp decline in the index of the website, and will slowly recover over time.

In the construction of general corporate websites, website construction companies are only responsible for providing website construction process and style design. As for the specific number of indicators and collections, this belongs to the scope of website seo.
