1. Painful experience 1: using software to send mass messages
As early as 2007, this method was quite effective. I used to sell software in this field and made a fortune, our products can send customer information to thousands of information platforms, and all of them can carry URL links. The success rate is about 80%, and there are some websites with high weights, at that time, these websites basically didn't need manual review, and it seemed that they could not find a way to block these software. Our product prices were not as cheap as thousands of items, and some customers started to buy one, later, I asked us to buy more than a dozen sets, and even the price was not paid back, you will know how good the effect was at that time, but after 2007, the product suddenly became not so easy to sell, the customer generally reported that the results were not good. At that time, I was not familiar with seo tutorials. Later, I found some large information platforms and set up the manual review function, A lot of information is deleted directly at this level, and many websites do not allow website addresses in the content at all. Therefore, the information sent later is basically some small websites with no weight, now Baidu has adjusted its algorithms, so it does not include the links to those small websites. You have sent too much and treat these links as spam links and directly use K websites. We are doing SEO, and it is best not to touch the group of software. The effect is not worth the candle.
2. Painful experience 2: failing to fully understand the keyword stacking problem
This is the most common mistake for new SEO users. You may think that this is not necessary because it is too simple. But what I want to say is that I used to think it is simple, but I still made a mistake, baidu K station used some webmaster tools because we checked the keyword density, and finally I found that these webmaster tools did not include the keywords in some places, for example, the keyword in the "alt" label in the image leads to a certain deviation between the data we see through the webmaster tool and the data we actually see, and through the study of other successful websites, we find that, some websites with a keyword density of less than 1% are still the top few in Baidu. It can be seen that the influence of the keyword density on ranking is almost negligible, so we do not need to set the density too high.
3. Painful experience 3: Baidu's misunderstanding of "original content"
"The content is king and the external chain is King". I believe that this sentence may not be heard for thousands of times, new webmasters who have no high-weight websites willing to exchange links will write some original articles on their own websites through their diligence, then, I posted these articles to some high-weight information platforms. I thought it was true that the website content was built and the effect of external links could be increased. However, please note that this is not far from the K station, because one thing you may not be able to believe is that, until now, Baidu and other search engines, especially Baidu, it is impossible to identify which website is sending original articles and which are collected. Generally, some high-weight websites, such as A5, outdated, and published articles are collected in Baidu in seconds, but can our own website receive messages in seconds? Obviously not. It may take some time for the search engine to view that our articles are collected, and the more we do this, Baidu will think that, the information on our website is collected, so our website will be deleted. In fact, Baidu's "original content" is not just about information. It also includes the website structure, user experience, and other comprehensive things. Only by doing this well, in order to enhance the value of your website
