如何针对Google图片搜索进行优化 | How to Optimize for Google Image Search
1. 生成有用且独特的图像 | 1. Create Useful and Unique Images
通过创建独特且有价值的图像(无论是照片、屏幕截图、插图还是信息图表)让您的网站与众不同。独特的视觉效果不仅可以使您的网站与竞争对手区分开来,还可以提高用户参与度。
Differentiate your website by creating unique and valuable images (whether photos, screenshots, illustrations or infographics). Unique visuals not only set your site apart from competitors but also increase user engagement.
2. 保持较高的图像质量和分辨率 | 2. Maintain High Image Quality and Resolution
搜索引擎优先考虑高质量、高分辨率的图像。Google建议提供"多张高分辨率图像(宽度和高度相乘至少50K像素)",纵横比为16×9、4×3和1×1。
Search engines prioritize high-quality, high-resolution images. Google recommends providing "multiple high-resolution images (at least 50K pixels when multiplying width and height)" with aspect ratios of 16×9, 4×3 and 1×1.
3. 使用描述性文件名 | 3. Use Descriptive Filenames
文件名应该是描述性的,但不能很长。例如,将文件命名为"tropical-green-smoothie.jpg"而不是"IMG_7489.jpg"。
Filenames should be descriptive but not too long. For example, name files "tropical-green-smoothie.jpg" instead of "IMG_7489.jpg".
4. 添加替换文字 | 4. Add Alt Text
描述性alt文本可以通过将图像与相关查询相关联来帮助提高排名。这也是一个辅助功能要求。
Descriptive alt text helps improve rankings by associating images with relevant queries. It's also an accessibility requirement.
5. 使用正确的图像文件格式 | 5. Use the Right Image File Format
选择正确的格式对于平衡图像质量、网站速度和SEO性能至关重要:
- JPEG:通用格式,平衡质量和大小

6. 压缩您的图像 | 6. Compress Your Images
正确的图像压缩可以在不牺牲质量的情况下实现更快加载。使用工具如Photoshop或在线服务如Imagify来优化图像文件大小。
