Web可访问性可以定义为：

但是，可访问性还涉及使Web内容对所有用户更可用：

虽然我们（很少）很少看到SEO社区中讨论的可访问性问题，但是搜索引擎优化人员肯定应该同时探索和实施可访问性标准：

通过增强（残疾人）的网站可访问性，您还使搜索爬网程序更易于访问该页面;

通过实施可用的工具来评估网站的可访问性，您还将发现网站的薄弱环节（从SEO角度来看）;

通过实施可访问性标准，您结束了可疑的SEO问题。

增强可访问性的步骤（来源：W3可访问性准则）：

注意图像：

包括对内容敏感的图像（即页面内容的组成部分）的描述性替代文本和标题：替代文本是盲人在替代图像时会听到的内容。 [SEO

: alt text is viewed as part of search crawlable content].

Don’t use alt text for decorative images (i.e. those that are meant to merely decorate the page). Assign an alt text to null value (alt="群光地铁站") so that the image could be completely ignored by screenreaders [

SEO

: if images are purely for decorative purposes, alt text should

probably

be skipped] .

Make sure your website provides written transcripts for all audio and video content – so that deaf people could understand what it says [

SEO

: written text is the best way to get search crawlers understand webpage content].

Mind your hyperlinks:

Make sure link anchor text makes sense out of context: blind Internet users often browse web sites by

tabbing from群光地铁站

one link to the next; thus if your site is full of "

click here

" and "

this site

" links, they won’t understand anything [

SEO

: this should put an end to an ever-lasting discussion if keywords should be included in external link anchor text: just make link text descriptive and useful].

Add "title=" attribute to links especially for non-descriptive anchor text [

SEO

: if you can’t do without meaningless link text, link title tag is your best bet to explain both search engines and people what the linked page is about].

Mark up documents with the proper structural elements :

use markup rather than images to convey information [

SEO

: again, nothing is easier accessed by search robots than pure text];

use heading elements to convey document structure [

SEO

: H1-H6 headings are used by search crawlers to understand page HTML semantic structure and its main topic].

Make sure the page content is clear with JavaScript and CSS disabled [

SEO

: any browser-enhanced functionality can cause problems for a search bot to access it].

Language:

indicate language used either through mark-up (with the "lang" attribute in HTML and the "xml:lang" attribute in XML) or

HTTP

headers [

SEO

: this will also help you avoid任何与语言相关的问题：请参见讨论];

提供缩写词和首字母缩写词的说明[
