SEO information query tool
This includes online tools and software that can be downloaded. It mainly queries SEO-related information, such as PR value, keyword density, keyword ranking, and reverse link number.
These SEO query tools are essential for optimizing the website's preliminary work. Dianshi has made a good summary of his blog.
Google clearly stated on their website that it does not like a large number of software queries. But as long as you don't have to go too far, it's not a problem to get someone else's server down.
Website diagnostic tools
There are few such tools. Currently, Webposition Gold is common. It will automatically analyze the differences between the web page and the previous web page, and then provide optimization suggestions. However, these tools are not yet mature.
Webposition Gold is not welcome if the domain name is specified by Google. In addition, because of the complexity and variability of search engine ranking algorithms, the suggestions provided by such software can only be used as a reference. If you have mastered the basic optimization technologies, you can confirm each other.
Content generation tool
For example, the webpage content is automatically generated based on the given keywords. As you can imagine, the content generated by this method is gibberish, a bridge page that search engines do not like.
Other software crawls search engine results or other website content, and crawls them onto your website. This kind of software should also be very careful when used, which may cause copyright problems or copy content problems.
Link generation software
This is mainly a mass mailing of comments from blogs in this forum. This software is currently very popular, but I still do not recommend it. Although it may not be regarded as a cheating method when it is well mastered, the search engine, especially Google, has a good judgment on such spam messages, at least the weight of the link is greatly reduced or even reduced to zero.
The more serious case may be the punishment to some extent. Of course, this kind of punishment will be very cautious, otherwise it will be too easy to hit competitors.
