HTML META tags are used

HTML Language Standard NOTES: Meta tags are very important to the development of the website, it can be used to identify the author, format the page, annotate the content feed and keywords, and refresh the page and so on.  

Google announced in 2009 that it would no longer use meta keywords or descriptions to rank (Ranking) in search algorithms.

A person in the search results before clicking on your link will see the page description, this also shows that should be added to the meta description, convenient for users to read rather than to facilitate the network robot to find . Overall, although a good meta description does not add to the site rankings, it will increase the click-through rate in search results.

Google has said that it is unlikely that algorithmic rules will change in the future, so don't meta expect any keyword tags.

In fact, the Baidu Chinese search engine algorithm is to consider the keyword tag as an important factor in the algorithm . So if you want the important part of traffic to come from a Chinese user, then you should add a keyword meta tag--but be careful not to use unnecessary and unethical keywords.

meta tags do not solve all of your SEO and accessibility issues , but they do play an important role in these areas. If you own a website, you can monitor the performance of your website by registering Google's website management tool . Once registered, if there are any related crawl errors, you will be notified, including some incorrect use of meta tags

These are some of the basic uses of META tags, the most important of which are: keywords and description settings.

Why is it? The reason is very simple, these two statements can let the search engine can find you accurately, attract more people to visit your site! According to the working principle of popular search engine (Lycos,altavista, etc.), the search engine first sends out the robot to search the WWW automatically, when discovers the new website, Search the page for keywords and decription, add it to your database, and then sort the site by the density of the keywords.

Other words:

1. If your page does not have keywords and description meta tags at all, then the robot will not be able to add your site to the database, users will not be able to search your site.

2. If your keyword selection is not good, the density of keywords is not high, is ranked in dozens of or even millions of sites after the possibility of being clicked is also very small.

So, we have to remember to add keywords and description meta tags, and write the keywords and profiles as much as possible.

The taboo to write keywords is:

1. Do not use common vocabulary. such as Www,homepage,net,web and so on.

2. Don't use adjectives, adverbs. such as the best, the biggest and so on.

3. Do not use general vocabulary, to be as accurate as possible. For example, instead of "Motorola mobile", use "V998", etc.

One of the tips for finding the right keywords: search engines such as Lycos,alta,infoseek, searching for sites that resemble your content, and reviewing the meta-keywords of the top ten sites to copy down to your site.

Here, we cite a Microsoft Multimedia website keyword for your reference:

<meta name= "keywords" content= "joke, music, MP3, media, audio,

Joke of the day, downloads, free music, horoscope, radio, video,

Music downloads, movies, radio station, Media Player, free,

Download, weather, horoscopes, Windows Media Technologies,

Online, radio station guide, free download ">

In addition, there are some "devious" to improve the search Ctr:

1. In order to increase the density of keywords, the keywords are hidden in the page (the text color is defined as the background color).

2. Add keywords to the ALT comment statement in the image.

such as:

3. Add a large number of keywords to the page code using the HTML comment statement.

Usage: <!---INSERT keyword here--->
