Alt标签和Title标签的区别在和使用讲解

Alt标签和Title标签都是用来为网页中的图像元素提供文字描述的标记。 Alt标签是一种HTML标签，用于为图像元素提供文本描述。这个描述在以下情况下会很有用： 1. 当图像无法加载时，Alt标签可以在页面上显示一个代替文本，使用户知道该图像应该出现的位置和意义。 2. Alt标签还可以帮助搜索引擎了解图像的内容和意义，从而对网页的排名产生影响。 3. 对于视障人士和使用屏幕阅读器的人来说，Alt标签是必要的辅助技术，帮助他们理解页面中的图像元素。 Title标签也是一种HTML标记，用于提供更详细的描述。Title标签的作用包括： 1. 当用户将鼠标悬停在图像上时，Title标签可以显示一个具有更详细信息的工具提示（tooltip）。 2. 对于链接或按钮等互动元素，Title标签可以提供更多的指示，例如告诉用户一个链接将带他们去哪儿。 3. 在搜索结果中，一些搜索引擎可以使用Title标签作为网页的标题，从而提高点击率。总体来说，Alt标签和Title标签都是非常有用的HTML标记，可以提高网页的可访问性和搜索引擎优化效果。区别在于Alt标签主要用于图像元素的基本描述，而Title标签则提供更详细的信息和指示。

网站图片的搜索引擎优化策略

我以前曾经提到过，网站的图片是非常耗费流量的，去年我就曾经统计过，两天的时间博客有20多G的访问流量，图片所在的目录upload占用了18.6G，而文章所在目录只用了1.3G流量，可见图片占用流量资源之巨大，这也就是很多人都喜欢将图片文件放在第三方免费网络相册的原因。然而，如果条件允许的话（比如有独立的服务器，充足的流量），那么将图片存储在自己的网站空间，反而可以利用搜索引擎的图片搜索给自己带来不

高质量图片，对网站SEO，为什么那么重要？

1、SEO图片优化竞争低从SEO的角度，所有的优化工作都是为目标流量所服务的，我们知道百度图片搜索，这部分的流量几乎是百度搜索流量的25%，由于竞争度相对较低，获取这部分的流量成本相对低廉，很多SEM与SEO从业者，开始精细化运营这部分流量。对SEO与SEM不清楚的朋友可见此文（SEO优化与SEM（竞价）区别在哪？）。2、符合行业发展预期我们知道从2017年开始，百度不断在调整搜索行业的发展方向，
