In our competition in particular the English SEO industry, we are in the persistent Google page rankings at the same time, should be more diversified to use Google other advantages of products? For example, Google's blog search, image search. Everyone is doing Christian Louboutin products station, at the same time, do you think a lot of netizens want to find a certain style or the latest style of pictures? This article will take the Christian Louboutin as the keyword image searches the previous several websites for example, Open an in-depth discussion.

However, this article does not intend to elaborate any new Google algorithm, and do not intend to explain any SEO techniques, but from the perspective of the search engine principle to analyze what we usually see, some of the phenomena known. So my friends from this article to get the search engine on the common aspects of things. Knowing the common, we can find more personality, will get more analysis of ideas, and finally formulate a strategy for their own optimization, ultimately in the blue Sea to win.

To get to the point, we started talking about how the search engine extracts pictures. When the search engine crawls any page, it involves two processes, one is extraction, the other is analysis. Extraction is an effective way to find image files, analysis is through a series of algorithms to analyze the representation and importance of the picture. Basically we can find a lot of on the network on the Picture site optimization a series of articles, but basically many are sweeping. For example, the URL path of an IMG tag includes keywords, a clear alt tag, or a title tag, a name for a picture file, and so on. Of course, what I'm describing here is not a comprehensive technical guide, but a discussion of several technical aspects of the search engine's concerns, for informational purposes only.

First, the search engine will be < img> tags for html files, < a> tags, the title of the page where the picture is located, hyperlink text for the page where the picture is located, pictures, URLs, < meta> tags, associated < a>, and < img> Structure, < div> structure, pictures surrounding the text to give the picture of the page for a comprehensive analysis. Then we have to pay attention to which aspects, we have to understand.

1, picture file name contains keywords (everyone knows)

2, the image of the IMG path contains keywords (everyone knows)

3, Alt and title tag contains keywords (everyone knows)

4, picture file size control. cannot be too large or too small, including file size and height-to-width proportional control. (A few know)

5, the importance of image format, JPG is more important than GIF. (A few know)

6. A picture with a hyperlink < a> tag is more important than a picture without a hyperlink tag. (Everyone knows)

7, the image surrounding the HTML are adjacent, so this brings the difficulty of extraction. Now the search engine has put forward a lot of algorithms for this problem, so we don't start the discussion here. (A few know)

8, the same page IMG tags on the same picture file reference times, different picture file format citations, to illustrate the different importance of the picture or different theme characteristics. (A few know)

Here is a Christian Louboutin example, you can analyze and discuss together. First put a Google search results map, we pay attention to the red circle area.

Through this example, we may be a little puzzled. Originally GIF weight should be lower than JPG, but in the 1,980,000 related results in the first page appeared, what is the reason?

Open http://www.debutanteclothing.com/news/tips/This page, you will find that the theme of this page is that the social flow of women's some dress, but also a similar News list page, through the above mentioned search principle analysis, You can find two special places.

1, this page is mainly illustrated, and most of the theme of the pictures appear in the < div class= "entry-content" ></div>, and each img tag with the theme of the Alt attribute, picture file name with the theme meaning The file name of the thought.

2, the key point is this page of a < div class= "entry-content" ></div> inside a "Christian Louboutin" the ALT attribute's IMG tag points to a file format that is in GIF format, All other pictures in the div are in jpg format.

Have two questions about this

1, in the same page of the same div structure of the different themes of the picture can complement each other, all explain the debutante mens??

2, can be like Google to provide the nofollow tag aggregation weights, through the specificity of the picture format to gather the theme of the weight of the picture??
