The Open Directory Project (also known as Dmoz) is a large public web directory hosted by Netscape. It is the largest global directory community maintained and constructed by volunteers from all over the world, and is classified according to the nature and content of the web page. DMOZ's content editing mode is similar to the category directory of the early Yahoo website, and it is also manually edited by the editors.

Open Directory

According to the relevant introduction on the DMOZ website, "The Open Directory Project is the largest and most extensive manual directory on the Internet. It is the largest global directory community maintained and constructed by volunteers from around the world." "The Open Directory Project is Contains the most extensive content, mainly classified manually. Its editors are mainly volunteers from the Internet to provide resources for the directory. The Open Directory Project provides the main directory service for the largest and most popular search engine and portal on the Internet. , Hundreds of websites including Netscape, AOL, Google, Lycos, HotBot, DirectHit, chinamulu, etc.

The open category DMOZ has always been regarded as one of the most important category websites. Correspondingly, the newly released website login DMOZ category has become one of the important work content of website promotion. However, according to the new research on online marketing tracking research, the actual effect of DMOZ category directories on website promotion is not high, especially for search engine optimization. The outdated website's summary information in DMOZ sometimes even hinders it. For the impact of DMOZ on search engine optimization promotion, analyze the article "DMOZ open category directory may become an obstacle to search engine optimization" in the New Competitive Internet Marketing Management Consultant and the new observation article "Open Category Directory DMOZ on search engines" "Are marketing important?"

As one of the free website promotion methods, the website login DMOZ category directory still has a certain role, this article introduces the role of DMOZ category directory on website promotion.

Logging into the DMOZ Open Category Directory is considered by many search engine optimizers to be a vital task, and getting a DMOZ link is also a difficult task. However, the reality is that DMOZ's open catalogs can become a barrier to search engine optimization. A simple example is that if you search with your website name, the content of the search engine search results is the description of the website when the website was logged in to DMOZ a year ago, and the actual content of the website has already changed. In this case, open-ended Instead, the DMOZ catalogue affected the normal search results of search engines and misled users.

A new observation and analysis article on online marketing "Does the open category DMOZ important to search engine marketing?" Believes that "DMOZ is not of high value to the website's search engine marketing. The main reason depends on some problems with the DMOZ category itself, such as DMOZ The time course of collecting websites, the problem that the information existing in the catalogs is not easy to update causes the catalogs to collect stale information. "

The mainstream search engines have clearly discovered the impact of this problem on the user's retrieval experience, so they try to guide the website to avoid search engine spiders from crawling the DMOZ category directory. MSN announced the use of the NOODP tag in May 2006 to prompt search engines not to use DMOZ description information (see "How to prevent search engines from crawling DMOZ information" for details). Soon after, Google also announced support for the NOODP tag.

How to use the NOODP tag to prevent search engines from crawling website summary information in DMOZ:

If your website has such a problem in search engine search results, you can use the following methods to solve the impact of DMOZ classification on search results:

As long as the website puts a piece of code: <META NAME = "ROBOTS" CONTENT = "NOODP"> in the HEAD area of the html file, it is equivalent to tell MSN and Google search engine spiders, please use the title and dessertption of this website as the search result information , Not the title and description used when logging into DMOZ on this site as search result information.

If only the MSN or Google search engine is refused to use the domz summary information, this code becomes:

<META NAME = "msnbot" CONTENT = "NOODP">;

Or, <META NAME = "googlebot" CONTENT = "NOODP">

DMOZ's content editing mode is similar to the category directory of the early Yahoo website, and it is also manually edited by the editors. However, one of the important differences between DMOZ and Yahoo's category directory is that the editors of DMOZ are not full-time personnel of the website, and These jobs are performed by volunteers around the world.

This is because there are many Very important search engines and online portals use DMOZ search results as their own search results. As one of the largest website directories on the Internet, DMOZ does not use automatic search programs like Google and other search engines to index and edit websites. The editing of the browseable categories is done manually. Therefore, when submitting your website to DMOZ, to ensure that the website is successfully included, you must pay attention to the following:

When Yahoo, the originator of the portal, created the first-generation search engine, it used a catalog approach. The earliest open directories in China are represented by NetEase and Sohu. In the early days of construction, NetEase search was mainly based on the search of classified directories, and created the earliest Open Directory Management System (ODP) in China. With the gradual development of technology, today's users are more accustomed to the simple search method of directly entering keywords, and keyword search has become a mainstream search mode.

With the rapid development of the Internet in China, the number of Internet users in China has exceeded 400 million, and the number of Internet websites has exceeded 3 million. The information provided by the Internet is endless. The service function of open directories has matched the growing demand for information query services for non-Internet users At this time, the development of Internet technology, especially the breakthrough development of search engine technology represented by Baidu in China, has triggered an industrial revolution of the Internet in China, subverting the way Internet users used the Internet in the past. Simply typing a few words on the search engine can accurately find the information you need, instead of having to find the relevant URLs in the URL directory in a time-consuming and laborious manner.

Although open directories have withdrawn from the mainstream stage of Internet search, open directories still have their important functions. The functions and functions of open directories in China have also changed relatively. The main changes are:

1. The URL query function of the open directory is weakened. With the development of search engine technology, open directories have been eliminated by mainstream search engines. With search engines, people can more easily and quickly find the information they need, and currently they are still using category directories (the branches of category directories " The hao123 website home group is mainly divided into several categories: First, people who are still accustomed to using URLs to categorize directories. The second is older people who are unfamiliar with Internet applications. The third is the people who are new to the Internet.

2. The URL quality evaluation function of the open directory has been enhanced. The submission of URLs for open directories is generally subject to manual review and manual evaluation. Therefore, the quality of URLs included in open directories is relatively high. High websites, search engines generally give better rankings.

3. The brand business card function of the open catalog is enhanced. General corporate websites and commercial websites are proud to be able to successfully submit open directories. Due to the reasons mentioned in point 2 above, websites that successfully submit open directories are of high quality and are recognized by netizens. Therefore, Being able to get the recognition of an open catalogue is equivalent to establishing a more authoritative brand name card on the Internet for general websites.

4. The classification function of the open directory is enhanced. The open directory is a collection of websites according to categories. After submitting the classified directory, not only will it be convenient for netizens to find, find and identify similar excellent websites, but it also collects and learns relevant industry information, data and analysis for industry researchers. Inferiority provides convenience.
