网站中图片搜索优化的方法
1. 图片格式优化：采用合适的图片格式，如JPEG、GIF和PNG。这些格式可以有效地减少文件大小，加快页面加载速度。
2. 图片命名优化：为了使搜索引擎能够识别图片内容，要将图片命名为关键字相关的单词或者短语。例如“red-apple.jpg”表明这是一幅带有红苹果的图片。
3. Alt属性优化：Alt属性是HTML代码中对图像内容作出正确描述的部分。Alt属性不但可以帮助浏览者理解当前所看到的内容，而且也可以帮助搜索引擎理解当前所看到的内容。
4. Title属性优化:Title 属性是 HTML 代 码 中 添 加 针 对 某 一 特 定 超 链 接 的 悬 浮 说 明 ， 有时也用来表明当前所看到的内容或者信息来去之间的关联关系。Title 属性也可以帮助 SEO 人士在 SERP (Search Engine Result Page)上得到好处,使得相关信息能够得到正常显示,避免出错情况发生;
5. Sitemap文件优化:Sitemap文件把站上所有URL都集中在一个XML文件里,然后将sitemap文件放在站上,并把sitemap URL告诉Googlebot(Googlebot是Google用来寻找Webpages/Websites/Images/Videos/News Articles/Blogs etc..), Googlebot就能够快速地寻找你站上想要indexing(Indexing is the process of adding web pages to a search engine's database.) 的images;
