If you do image site optimization work

Http://www.aliyun.com/zixun/aggregation/13355.html "> site production often ignores the search optimization of the picture, we all know that search engine can not recognize the text on the picture, So the focus of the optimization is the picture's attributes and the environment of the Web page, but not all the pictures on the page to be optimized, some decorative effects and some button pictures do not need. Because this article is specially to the picture station optimization and wrote, so I took my station to do an example also counted as an advertisement (funny picture http://www.iptry.cn).

For the picture station summary of the following points must be carefully read:

alt-instead of attributes:

Search engines think that the pictures on the Web page should be related to the theme of the page. Conversely, when the search engine to judge the keywords of the Web page, the image of the alt-in place of attributes is a trustworthy reference point. So, don't forget to add the keyword of the page in the alt-of the picture instead of the attribute. Sometimes the pictures on the Web page can't be displayed because of some reasons, such as using screen readers, low bandwidth, network blocking, and so on. Descriptive alt-instead of attributes can tell the user the content of the location to add the user experience. Regular websites should do the same. Sometimes, if there is no alt-in place of the attribute, it will cause the user to not understand what the picture represents and why it is placed on this page.

Worst (but most common): <img src= "nt12343.jpg" alt= "/>
Slightly better (but did not tell the user specific content): <img src= "nt12343.jpg" alt= "Baby"/>
Best (simple description of picture content, and nested keywords): <img src= "nt12343.jpg" alt= "Baby two Birthday Eat cake" >
is considered spam spam website: <img src= "nt12343.jpg" alt= "Baby sweetheart cake cake birthday baby Birthday"/> ...

PS My practice is very simple is alt= "page title + first few"

One more thing I personally feel more important is such as the focus of the Web page on 1 pictures, if there are many buttons on the page or decorative pictures of the key picture of the size of the larger than other pictures of the best has a very obvious size contrast. The best thing to do is to decorate the picture with a div background to display the entire page on a. jpg or other picture format connection.

Picture naming: Although we use the image search, usually entered the keyword in the majority of Chinese characters, but the Chinese character name picture is not desirable, browser support and interpretation of Chinese characters is very unstable, so we suggest as far as possible in English words or abbreviations as a picture of the file name. If the site is a number of CMS programs, due to the large number of pictures or the default file name for good, clear directory structure, and good management. PS My funny picture site, with the DEDECMS program, the image directory to create a daily file by the time name is good.

Content keywords: The image of the page in the text and users to use the image search input keyword matching degree, but also determines the image ranking important factors. If the picture is named "SEO", and the whole article is talking about food, it is obvious that the search engine will think that the picture on the page and the picture that the user wants is far away. PS My usual practice is to repeat the title 3 times on one page.

Like "Funny Picture" is the title

1. Funny picture//general use H2 label

2. Funny Picture profile//H3 a text in repeated keywords 2-3 times

3. Funny Picture related Atlas//H3 is connected to the site of the atlas

4. Funny Picture comments//H3 I don't have this on my website.

Web naming: All efforts are to let search engines feel that your Web page and pictures are closely related, so I suggest that the page and picture naming as far as possible to set the same, if the picture is seo.jpg suggested that the Web page named Seo.htm, of course this method can be for less pictures of the station. PS like I do the station each atlas has 10-30, updated every day 3-5 pictures have hundreds web page if each page is named, it will become an idiot. The large number of pictures can only be named using the program. DEDECMS Program supports custom URLs I am by (site/column name/year/day ID) sort of people can look at my station on the way to name the page.
