The application of Lynx browser in SEO

Once a friend asked me how to judge a seoer is not a master. I had an idea, and advised him to ask that seoer is not aware of Lynx in the SEO application method. So to ask questions, in fact, can reflect from a side of this seoer on SEO research how deep.

SEO industry Now, although there are a lot of misinformation, but if you practice often, still can find a lot of really useful methods of operation. Practice for a long time, can also judge who said the right, who said there are problems, such seoer, you can rest assured that he to operate some of the more important sites. Further to the site of the details of the optimization process, you will find that many people have not talked before, it is difficult to optimize some small web site in the process of noticing the details. These details are hard to find in other places, or they can't be found at all. But in Google's Google website quality guide, Google Blackboard, Google Chinese webmaster blog, basically can find a few words about these details. It's just that it gives a direction, more specific details or you have to rely on yourself to practice.

On the first page of the Google website Quality Guide, you have been advised to use the Lynx tool area to test your site:

Use a text browser such as Lynx to check your Web site, because most search engine information acquisition software looks at your site almost the same way as Lynx. If complex features such as Javascript, cookies, session IDs, frames, DHTML, or Flash cause you to not see the entire site in a text browser, search engine information acquisition software may experience problems crawling your site.

Here is the "Lynx view of the site and search engine almost the same way." A seoer, if really to a lot of details can not be from others to obtain the degree of reference, then this paragraph believe that he is difficult to ignore.

I spent a period of time lynx, found that the once text browser and search engine crawler is very similar. You have heard of the reptilian characteristics, you can find a little shadow here.

For example, detection of hidden links, we only know that search engines do not like, but the specific detection method is what? If you use ripe lynx, you will find a very simple command to be done.

First of all, to build a Lynx operating environment. Lynx cannot use a compiled version that runs under Windows, and there are many features that are not available. It is recommended to install a virtual machine under XP and then install a Linux system in the virtual machine to run Lynx.

Virtual machine software with VirtualBox or VMWare, the specific installation method everyone Google. The Linux system recommends Ubuntu, which installs Lynx on the graphical interface.

In the Lynx Linux system in command mode input: Lynx-dump www.alibaba.com and enter, the hidden link on this page is at a glance. Such as:

Hidden Link Detected

And then further analysis, which link lynx would think is a hidden link?

As you can see, at least one of the following links is Lynx considered to be a hidden link. The code is:

<a href= "http://www.alibaba.com" > </a>

This link, that is, no text as anchor text, and no pictures or other objects as links. If you do not load the CSS file or JS file, the light on this code, on the Web page is not see the existence of this link. Of course this is the hidden link, there is no controversy.

This is what Lynx thinks, and search engines are the same. From the entire Internet, this detection method in 99% of the case will not be wronged a website. For Google, a detection method, if more than 40% of the cheating efficiency, that is a very good way.

A non-cheating site, the reason for this situation, is because the Web designer's some "strange" code. If you're testing your site, you might be able to see these hidden links as well.

Of course, the role of Lynx is more than that. It first shows what the crawler sees with a visual perspective. Use it to check your Web pages to show what the search engine crawler has to offer. Such as:

What Lynx saw.

Then there are some other features:

You can detect the integrity of your Web page code. If you are prompted to have "bad HTML" you should pay attention.

You can view the source files like ie. The order is in the appendix.

The tracking of cookies is treated in a special way. will prompt you whether to follow cookies.

The process of framing and forms is the same as for reptiles.

URL too many parameters, can cause browsing difficulties.

can view HTTP header information returned by a Web page

......

You'll see a lot of familiar things.

The advent of Lynx was the time when the first reptile program was born. There are quite a few reasons to believe that they are the same idea. And now maintain and update Lynx's people, some of them are also maintaining other Open-source crawler programs. You can actually think of Lynx as a visual crawler.

HTTrack is a relatively macroscopic crawler simulator. and Lynx is more detail, and more practical.
