Why do spiders suddenly stop crawling websites?
When many novice network promotion experts and optimization personnel enter the optimization industry for the first time, they will inevitably ask some questions about why the website is not included, and why there are no spiders in the website log, but in fact, such problems are not so difficult, and I will take you next. Careful analysis can help you better solve these problems.
1. You blocked the spider
If you block spiders yourself, spiders can't grab your site. One is the robots.txt file set up to avoid site imperfections and spiders from crawling. If found, please delete them in time. Another is that the service provider blocks spiders. There are too many spiders crawling websites, which causes the server to think that it is a doos attack to automatically block the spider IP. In this case, the website is often K. If this is the case, you may wish to change the service provider directly. So as not to bring a bad experience to the site.
2. Spiders block you
When registering a domain name, check if your domain name was used or penalized before registration. The spider itself has an opinion on it. If it is such a domain name, it is better to change the domain name.
Check to see if any website with the same IP as you is penalized. Maybe this website was seriously violated by station K, so the search engine has the function of automatically blocking the entire server. Internet promotion experts suggest that using a dedicated IP is good for SEO.
3. Learn to use logs to understand the law of spider crawling
Novice optimizers should also learn to use software to analyze which folder spiders crawl, the number of crawls, etc., to help you better analyze website optimization problems, and then make better optimization plans to help website rankings improve quality.
The points summarized above are the reasons and solutions for why spiders suddenly do not grab the website. Optimizers can better learn optimization techniques and help website rankings improve.
