图片Alt属性的本意主要是当图片因某些原因不能正常显示的时候，网页访问者也能够通过属性文本判断该图片的内容，其原本意义是为了用户正确了解网页信息而不是为了搜索引擎。

The original meaning of the alt attribute of a picture is that when the picture cannot be displayed normally for some reasons, web page visitors can also judge the content of the picture through the attribute text. Its original meaning is for users to correctly understand web page information, not for search engines.

跟很多不重视Alt标签相对的是在Alt中过度堆砌关键词，其目的为了增加页面关键词密度，实际在一个文字占主要部分的网站根本无需刻意利用Alt嵌入关键词，文字部分就够用了，只有那些图片站才有必要在Alt上下下SEO的功夫，当然并非说文字够了，Alt就可以空下来，这是不好的习惯。首

Compared with many people who don't pay attention to alt tags, the purpose of over stacking keywords in ALT is to increase the density of page keywords. In fact, in a website with text accounting for the main part, there is no need to deliberately use ALT to embed keywords. The text part is enough. Only those picture stations need to work hard on ALT SEO. Of course, it doesn't mean that if the text is enough, ALT can be empty. This is a bad habit. first

先你少了一个让搜索引擎读懂图片的参考因素，无疑是搜索引擎不友好的。其次，适当的描述说明并嵌入相关的关键词，是可以增加图片在百度图片中的排名的，Google，搜狗都一样，不过单单这个因素不足以让图片排名好，搜索引擎有能力对图片进行一定维度的识别，都会影响到他是否有机会被收录和给与排名。

First of all, you are missing a reference factor for search engines to understand pictures, which is undoubtedly unfriendly to search engines. Secondly, proper description and embedding relevant keywords can increase the ranking of pictures in Baidu pictures. Google and Sogou are the same, but this factor alone is not enough to make pictures rank well. The ability of search engines to identify pictures in a certain dimension will affect whether they have the opportunity to be included and ranked.

Alt被滥用的做法已经淘汰了，取而代之的是很多人对其如何使用的无所适从。要么像有的站一样极少有说明，或者草草应付，要么不知道如何做，小心谨慎的放上一些嵌入关键词而文法不太通的句子短语。就这个我下文说说。

The abuse of ALT has been eliminated. Instead, many people don't know how to use it. Either there is little explanation like some stations, or deal with it hastily, or don't know how to do it. Carefully put some sentences and phrases with embedded keywords and grammar. Let me talk about this later.

页面图片也有轻有重。比如小图标more，单纯的给个more或更多就行了。万一图标加载不出来，也不至于让用户找不到入口。按钮也一样。也即不打算也没什么重要seo用途的，常见的图标，就按实给它简短的名字好了。

Page pictures are also light and heavy. For example, the small icon more, simply give more or more. In case the icon cannot be loaded, it will not make the user unable to find the entrance. So is the button. That is, for common icons that are not intended or have no important SEO use, just give them a short name according to the actual situation.

其他的可将该页面的关键词进行分词后，组合成若干个词，然后根据图片信息进行匹配，尽可能准确描述图片，在做Alt的时候假设自己是用户，遇到图片没有加载或者缺失的情况，给与什么信息能让用户知道是什么。

For others, the keywords of the page can be segmented and combined into several words, and then matched according to the picture information to describe the picture as accurately as possible. When doing alt, it is assumed that you are the user. When you encounter the situation that the picture is not loaded or missing, what information can be given to let the user know what it is.

济南网站开发人员认为在seo中换位思考是一种省事的策略。比如一个做机械设备的网站，设备名就是好的Alt，当然在图片选择呈现上以及描述的调整上，需要加进seo的因素。尽可能选贴近主题的图片及描述。让页面呈现出高度相关。

Jinan website developers believe that transposition thinking in SEO is an easy strategy. For example, for a website that makes mechanical equipment, the equipment name is the best alt. of course, SEO factors need to be added in the selection and presentation of pictures and the adjustment of description. Choose pictures and descriptions close to the theme as much as possible. Make the page highly relevant.
