对于内容丰富的电商网站、新闻门户或企业博客而言，为成百上千张历史图片手动编写描述性Alt（替代）文本不仅令人抓狂，也耗费了巨大的成本。Alt文本对于提升Google图片搜索排名至关重要，也是让视障用户通过屏幕阅读器理解网页内容的关键。我们的AI工具应运而生，一次性解决这一长期痛点。
不再让图片SEO成为您工作的瓶颈。让AI为您代劳，帮助您的网站获得更完善的结构化数据，以及源源不断的自然搜索流量。
Everything you need to know about optimizing your assets
Alt文本是HTML标签中用于描述图像内容的属性。搜索引擎爬虫“看不懂”图片，只能通过读取Alt文本来理解图片主题。编写良好的Alt文本能大幅提升该图片在搜索引擎中的排名曝光率。
是的。我们的AI经过专门提示词优化，遵循最佳SEO实践：直接描述图片主体、不使用冗余的“一张……的图片”开头，并将长度控制在合理的字符范围内。
AI拥有强大的OCR（光学字符识别）和常识识别能力，能够捕捉画面中明显的品牌标志、包装上的显著文字，并将其合理融入到描述文本中。
CSV文件中包含两列：原图片的文件名，以及对应生成的Alt描述文本。您可以使用Excel打开它，或者直接利用插件批量导入到您的CMS系统。
目前的系统默认输出高质量的英文Alt文本，因为这是国际化SEO最稳妥的选择。如果您需要其他语言，可以在获取结果后使用翻译软件批量处理。
绝对可以。在工具界面显示生成结果后，您可以直接点击文本框进行编辑和微调，确认无误后再点击导出列表。
得益于强大的后端AI引擎并发处理，通常每张图片的分析生成只需要1到2秒。上传几十张图片只需短暂等待即可获得完整的报告。
为了保障所有用户的服务体验以及防止接口滥用，单次上传的图片数量有一定上限。如需超大规模处理，建议分批次上传。
