Recently, and friends to talk about such a topic, is engaged in SEO need to understand the procedures and network security knowledge, friends think that every day to optimize the work has been very tired, if you have to learn this again and learn that, but nothing is fine, more likely to end up eclectics taste. But the author thinks, if we do SEO, can regard oneself as a stationmaster, at the same time put some useful knowledge to learn, not only to the website internal structure more understanding, and to the whole station optimization will have great spleen, the following is the author's personal view:

First, do not need to master web design, but at least to understand ingenious

For example, many friends now like to use a number of open source CMS or WordPress, such as open source programs, because only need to adjust a few parameters, change the URL and edit the column layout and so on, then you can start the webmaster's Road to sail, Such a low threshold can make more people have the opportunity to become stationmaster.

However, in the optimization of the SEO process, often accompanied by a variety of situations, such as the site's page selection, in the end is the use of static pages, dynamic pages or pseudo static page? If you are using a static page, it is easy to install settings, but if there is any change in the layout of the site ( If each page needs to display the latest articles or recommended articles in real time, it is easy to make the server appear very busy and instantaneous when updating the page. At this point if we use pseudo static page, not only can the whole station in real time to update the page, so that spiders can crawl more fluent, but also in the user experience will be better.

At this point, for the pseudo static page rules specified, such as page parameter settings, if you know the PHP pass, know the description, will be less, and the same technology can also be applied to Baidu Webmaster "website revision" in.

Second, the application of the database is necessary to understand

In the optimization process, if we focus on optimization in the station, then you should often encounter some of the page is the spider ignored the situation, at this time we can use a lot of effective means to carry out the guidance of spiders, such as related articles recommended, as well as contextual recommendations, and so on, through a variety of links to the way, so that spiders can crawl more smoothly, This will allow those flooded pages to be included in the search engine opportunities.

In addition, in order to make the site similar to each page is not too high, we can also use the unordered sorting function to list the title of the article when we recommend it, instead of the traditional order or the reverse, as long as we know that the SQL statement "orders by RAND ()" can easily achieve the disorderly arrangement function.

However, since this sequence of instructions is extremely inefficient, the query time becomes longer when the amount of data is slightly higher, so if we understand a more in-depth SQL statement, such as "SELECT * from table where id>=" (Select Floor (rand () * ( Select Max (ID) from table)) The ORDER by ID limit 10 ", you will get more effective random results, and the query time will be greatly reduced.

Third, the basic knowledge of network security is necessary to master

Believe for many friends, should try the Web server is DDoS attack, resulting in high CPU utilization ... The result is that the site crashes, and every time that happens, it has to be restarted.

The author has been such a painful experience for several months, when the company's Web site every few days will appear CPU utilization up to 100% of the situation, so that no one can not browse the site, not only caused the loss of customers, but also almost let the site was Baidu down the right, so I remember this situation.

At this point, we just need to install some anti-attack software, the situation will be slightly improved, but another situation will occur-the choice of high-intensity protection will be shielded spiders, that experience is very scary, because the author has witnessed Baidu index-3000 of the situation occurs, when the site's total index is more than 3,200. In other words, almost the whole station by K.

Later a check site, that the SEO has not been an excessive optimization, there is no hair outside the chain, just in the station to carry out a regular original article update, completely does not involve the scope of Baidu ban, and then the anti-attack software uninstall less than 3 days, those indexes back again, although it is a false alarm but also very scary To know that the days by K not only all top-level domain names and two domain names are missing, and the remaining number of pages in the few. Through the webmaster Home and Love station Network ranking query function to find all the rankings have vanished ... For the same is rely on search engine to eat the webmaster friends, this experience is how scary, I believe we should be able to understand it?

In fact, the knowledge of network security, not only can we try to avoid the situation of attack, and if the site is breached and lead to be hung black chain, we can know how to solve.

Iv. Summary

Although SEO named Search Engine optimization, Chinese translation for "Search engine optimization", in fact, many times is to do a webmaster to do things, from the site layout to the content of the page arrangement, the promotion of the website and network security preparedness work, and so on.

The author does not think that SEO should be a eclectics, just in the actual site operation process, these problems will not come, so you can not help, want to avoid hiding. In order to let the consumer experience better, in order to allow spiders to crawl smoothly, we have to learn something more, so that the site can be flat and stable operation.

In addition, I think, if we are in the SEO optimization work at the same time, can put the mentality of stability, regard themselves as the site webmaster, attentively maintain the site. When we can understand the overall layout of the site, and understand the Web site of the potential consumers of the consumer psychology, then our harvest will be greater, our road will be better off.
