圖片Alt屬性的本意主要是當(dāng)圖片因某些原因不能正常顯示的時候，網(wǎng)頁訪問者也能夠通過屬性文本判斷該圖片的內(nèi)容，其原本意義是為了用戶正確了解網(wǎng)頁信息而不是為了搜索引擎。

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.

跟很多不重視Alt標簽相對的是在Alt中過度堆砌關(guān)鍵詞，其目的為了增加頁面關(guān)鍵詞密度，實際在一個文字占主要部分的網(wǎng)站根本無需刻意利用Alt嵌入關(guān)鍵詞，文字部分就夠用了，只有那些圖片站才有必要在Alt上下下SEO的功夫，當(dāng)然并非說文字夠了，Alt就可以空下來，這是不好的習(xí)慣。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

先你少了一個讓搜索引擎讀懂圖片的參考因素，無疑是搜索引擎不友好的。其次，適當(dāng)?shù)拿枋稣f明并嵌入相關(guān)的關(guān)鍵詞，是可以增加圖片在百度圖片中的排名的，Google，搜狗都一樣，不過單單這個因素不足以讓圖片排名好，搜索引擎有能力對圖片進行一定維度的識別，都會影響到他是否有機會被收錄和給與排名。

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被濫用的做法已經(jīng)淘汰了，取而代之的是很多人對其如何使用的無所適從。要么像有的站一樣極少有說明，或者草草應(yīng)付，要么不知道如何做，小心謹慎的放上一些嵌入關(guān)鍵詞而文法不太通的句子短語。就這個我下文說說。

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.

頁面圖片也有輕有重。比如小圖標more，單純的給個more或更多就行了。萬一圖標加載不出來，也不至于讓用戶找不到入口。按鈕也一樣。也即不打算也沒什么重要seo用途的，常見的圖標，就按實給它簡短的名字好了。

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.

其他的可將該頁面的關(guān)鍵詞進行分詞后，組合成若干個詞，然后根據(jù)圖片信息進行匹配，盡可能準確描述圖片，在做Alt的時候假設(shè)自己是用戶，遇到圖片沒有加載或者缺失的情況，給與什么信息能讓用戶知道是什么。

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.

濟南網(wǎng)站開發(fā)人員認為在seo中換位思考是一種省事的策略。比如一個做機械設(shè)備的網(wǎng)站，設(shè)備名就是好的Alt，當(dāng)然在圖片選擇呈現(xiàn)上以及描述的調(diào)整上，需要加進seo的因素。盡可能選貼近主題的圖片及描述。讓頁面呈現(xiàn)出高度相關(guān)。

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.
