优化网站图像的5个方便的技巧

Did you know that 图片 not only make your website more attractive and engaging to customers, 但它们对你网站的SEO也很重要? If optimized correctly, 图片 can improve your site’s page loading speed and search engine ranking. Here are some tips for optimizing website 图片.

什么是图像优化?

Image optimization is the process of delivering 图片 in the correct size, 格式, 决议, and dimension without compromising their quality. The goal is to improve the loading speed of websites to give visitors a better browsing experience.

如何优化网站形象

Here are helpful tips for optimizing the 图片 on your website.

1. 选择正确的文件格式
Digital 图片 come in various 格式s, but the three most commonly used types for websites are:

  • jpeg文件 – jpeg文件 are the most widely used 格式 for website 图片 because they have an enormous color palette that’s ideal for showing off 图片 with complex patterns, 梯度, 阴影, 和颜色.
  • png – png support a wider range of colors compared to JPEGS, making them ideal for 图片 with more complex designs. png are also the only 格式 that can support transparent backgrounds perfect for logos and 矢量图. The only drawback is that PNG files are larger than jpeg文件, which can make page loading times longer.
  • gif – gif are hugely popular as animated memes on social media sites but are hardly used for static 图片 on most websites because of the limited colors — only 256 — they support.
    Therefore, they are the best option for small 图片 that require only a few colors.

2. 正确命名你的图片
It’s important to use relevant 关键字 when naming your website 图片 because search engines like Google not only crawl the text on your website but also crawl image file names. Using keyword-rich and descriptive image file names will allow search engines to provide more accurate results to customers looking for a particular product or service.

For example, if your website is selling used cars, naming an image Red-Ford-Mustang-LX-2012.jpg will get more search results compared to a generic file name like used-car.jpg或DCIMIMAGE001.jpg.

3. 使用alt标签
Alt tags are texts that appear in place of a website image that fails to load on a user’s screen. These tags allow screen-reading tools to describe website pictures to visually impaired visitors. In addition, alt tags help search engines crawl and rank your site better. Most of the time, alt tags are almost similar to image file names.

4. 调整你的照片
Using the wrong image size on your site can negatively impact loading times. For example, featured 图片 in WordPress are usually 1200 x 628 pixels. Images larger than 1200 x 628 pixels will decrease the loading speed of your site. 这会导致情绪高涨 放弃率.

5. 压缩你的照片
Image compression is the process of reducing an image’s file size without compromising its quality. 这允许你在你的网站上使用更多的图片. The smaller image file size also helps in reducing the time needed to download or send an image over the internet.
