At present, in most domestic SEO training institutions, meta tags are the first lesson they teach, because there are advantages and disadvantages to the use of meta tags. I am also thinking about how to write about this topic, because we always hear about the disadvantages of meta tags, and many people just know that keywords are written in meta tags. The first thing that needs to be carefully analyzed and explained is that many websites abuse meta tags, mainly because they put meta tags at the top of all pages, so they are seen first. However, we don’t want people to have too many misunderstandings about meta tags. In fact, in the eyes of search engine marketers, meta tags are a very good tool.
There are many attributes of meta tags, not just description and keyWords. Although these two attributes are the most important, I see many people abusing meta tags, including good, neutral, and bad, and I feel speechless. In this article, I don't cover all the properties of meta tags, but you do need to pay attention to meta tags if you are interested in this.
In this article, I mainly write about the core parts of commonly used meta tags, and I will not write about some meta attributes that may make you feel useless and take up space. Useful meta tags will gradually improve your ranking, while useless meta tags will keep you where you are forever.
1. Very useful meta tag attributes
These meta tags should be displayed on every page. Below is my list of useful meta tags. There are only two that are most necessary to use, so if you can make these two useful, then please use them. .
1. Meta content type
This tag is necessary to describe the characteristics of your page and should be placed on all pages. Omitting this tag may affect the display of your page in the browser. This is the content type. Here are two brief introductions:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8″ />
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
2. Description of meta
Meta descriptions have only one purpose, which is to describe what this page does to searchers. This tag does not affect rankings, but it is important. This is an ad that determines whether a user clicks on your page. Keep descriptions to 160 characters and write them in a way that grabs the user’s attention. Descriptions promote your page well.
2. Seven commonly used meta tag attributes
This kind of meta tag does not matter whether it is useful or useless. This is for different sites. If you feel that it does not matter whether you use it or not, then it is recommended that you still use it. It’s not too much to use it, and it won’t have much impact if you don’t use it. This is the meta tag here. I will analyze each function in detail below.
1. Robots
One of the biggest misconceptions is that you have to use robots in meta tags. Let us clarify our thinking. As far as indexing and link following are concerned, if you do not specifically emphasize the use of robots tags, then the search engine will read the page according to the default index and follow. When you want to change these two commands, you can specify meta robots. If you want the page not to be indexed, but allow links to follow, you should use noindex and follow settings.
<meta name="robots" content="noindex" />
2. Specific Bots (Googlebot)
These tags are used to give a special robot instructions like noodp and noydir. Generally speaking, search engines handle this kind of thing very well, but if you think you need it and are considering using it, then consider using it.
3.Language
The only reason to use this tag is if you move your site to another country and need to declare the primary language on the page. To check the original languages you use, make an exhaustive list.
4. Geo
This tag, which is mainly effective for Bing, does not work for Google. There are three types of tags: place name, location (including latitude and longitude), and region
<META NAME="geo.position" CONTENT="latitude; longitude">
<META NAME="geo.placename" CONTENT="Place Name">
<META NAME="geo.region" CONTENT="Country Subdivision Code">
5.Source
This is the latest label released by Google. The purpose of this label is to help search engines identify who is the original news provider. It can also help search engines determine who is the original content of a piece of content and who is a reprint. This is still very useful in the current era of Internet knowledge.
6.Refresh
In the opinion of the industry, this is the worst redirection method, and if possible, it really should not be used. If you want to redirect, it is best to use 301 permanent redirection. This situation often happens to some programmers who don't understand SEO.
7. Site Verification
Can your website be properly verified by Google and Bing? When my website does Google Adsense affiliate advertising, it requires verification of website ownership. In fact, we will encounter this in many cases. Sometimes it is necessary to use this tag, but if you want to use it as another way to verify whether the website is yours, it will not be worth the gain. Google allows you to upload a file they provide via DNS, or by connecting to your Google Analytics account. Bing also only allows you to verify website ownership through xml files or meta tags, so if you feel comfortable with it, go with the crowd and verify website ownership this way.
3. Ten uncommon meta tag attributes
If you use these meta tags, your site will not change at all, only the website code will be added. Google has also said that these tags are useless and will only waste space, so it is best not to add these useless meta tags. So what are these labels?
1.Author/Web Author
This tag is used to name the author of this page. It is not necessary to use this on the page.
2.Revisit After
This tag is used to give robots a command to return a page at a specific time. It is not recognized by any major search engines.
3. Rating
This tag is used to indicate the content's maturity rate. This can give a signal to search engines and is the best way to distinguish bad images, such as adult images. However, search engines believe that this content requires people with a certain maturity to view it.
4.Expiration/Date
The Expiration tag is used to mark the validity period of the page, and Date is used to mark the creation date of the page. Just think about it, is it necessary to set an expiration date on your page? It is useful to make an xml map for dates and keep the xml map updated over time.
5. Copyright
Google can already identify the copyright of an article. Looking at the bottom of your website, I think it must be written like "Copyright 20XX". Why do you have to say copyright twice?
6.Abstract
This tag is mainly used to put content summaries. Whether to use it or not depends on personal preference.
7.Distribution
This label is generally used to control who can access the document. A typical setting is global. This is inherent if a page is opened.
8. Generator
This is used to indicate what program created this page. Like author, this tag is useless.
9. Cache Control
This tag is used to set when and how often a page will be cached by the browser. It is best to do this in the http header.
10. Resource Type
This tag is used to name the resource type of the page, such as "Document Type". In order to save yourself time, you can use DTD to verify it.
I have summarized some of our common meta tags, and many of them are not familiar to everyone. I have also written them down here. I hope everyone can understand the role of meta and avoid misunderstandings about website optimization. As the saying goes, know yourself and know your enemy. Only then can we survive a hundred battles. I hope this article can inspire newcomers, and everyone is welcome to communicate with each other and discuss all aspects of optimization.
