SEO for website images deserves special attention because images are an important factor when search engines rank a site. Search engines store images associated with each keyword and display them in Baidu Image Search. Once an image reaches a certain level of downloads, it may be treated as more important for that keyword and receive comparatively greater weight and a higher ranking. This means image SEO requires both a clear strategy and technical considerations. So how should images be optimized for SEO? Below,a Beijing website development companyshares professional guidance.
Give Every Image an ALT Tag
ALT tags help search engines understand an image's content and give the image an opportunity to be crawled and indexed.
Use ALT Tags Appropriately
When writing an article or other content, first review the paragraphs above and below the image. Extract language from the surrounding context and use relevant keywords in the ALT tag to strengthen content relevance.
Image Watermarks
Watermarks are another important detail. When content is promoted online, unwanted copying is a common concern, so watermarks can help promote the website and protect copyright. They can also make it easier to share articles more broadly with the public.
Number of Images
The number of images should also be controlled in SEO. Too many images increase page weight and make layout more difficult, so unnecessary images should be omitted unless the site is specifically built to provide photography. Most sites do not need many images, but those they use should be high resolution.
Absolute Paths for Image SEO
The paths commonly used during optimization are often dynamic, meaning their locations can change and they can be used across different sites. An absolute path, by contrast, does not change and is specific to the website. Using absolute paths is a strong approach to website path optimization. Paths should also follow a consistent structure and classification system. Pinyin can be used for path names, with abbreviations for longer terms.
Adding Reciprocal Links
When exchanging reciprocal website links, avoid using image-based links where possible. They are far less effective than text links for image SEO.
Image Dimensions
Images should not be excessively large, because larger dimensions consume more website resources. However, images that are too small may not serve their intended purpose. Use dimensions appropriate to the display context; a 3:2 aspect ratio is generally preferable.
Image SEO methods and techniques depend on careful execution. Poor rankings do not always indicate a fundamental website problem; they are often caused by insufficient attention to optimization details, leading Baidu to assess the site as lower quality and rank it accordingly.
