Since the search engine does not have a perfect wit to identify the picture, then we will help search engine identification, according to our experimental experience, the following summed up a few suggestions for you to refer to the discussion.
One alt label
The picture must add the Alt label, the ALT label occupies the very important position in the picture search, what you do is the picture, this alt label must have this text, Andy Lau's picture, must tell the search engine, I am not Jay Chou.
Two picture titles
This is the same as the title of the page optimization, is a picture of what content, give this picture to take a consistent title.
Three picture formats
At present, the search engine picture library, most pictures of the file format is Jpg,jpeg,jif, the jpg,jpeg,gif as a suffix to complete the picture.
Four Picture Text introduction
In front of the picture, basically is a column about this picture, to tell the search engine the importance of this picture.
Five External links
Site optimization needs external links, the same, the image of the SEO optimization is also required external links, links are always the most fundamental foundation of the network, the best pictures will spread on the network, search engine is to analyze the image of the external links, so as to determine whether this picture is popular.
At present, the SEO industry, we are focused on Baidu, Goolge,yahoo and other major search engines of the web search, the search optimization of other products is very little, Baidu many products in addition to Web search, MP3 search, image search also gathered a huge popularity. According to my station (www.mm941.cn) data statistics show that the current picture search about the total number of Baidu search 55%-60%, so for "Baidu Image Search Optimization" is a very worthwhile thing we do
However, for Baidu to do image search engine optimization, is not an easy thing, it is not as easy as web search engine optimization research. The main reason, the current search engine is not very good to identify the picture information, the picture is not like words, search engine on the text content recognition, through its own text recognition system, to identify, even if the information is a deviation, but not too outrageous. But the composition of the picture is binary machine code, even if the search engine such as Google, it is not very good to identify which picture is the most important picture. Therefore, more hope that we further explore and study.
My station http://ayif.com.cn hope can and more admin5 webmaster friend exchanges, common progress!
