The use of alt tag in website optimization is also a very important detail, but the visual effect of alt tag is not obvious, which is often easily overlooked and will also affect the overall evaluation of the website by search engines. So, how to use alt tags in the process of website optimization? Next, let's take a look at the use of alt tags in the SEO optimization process of websites.

First, the use of home page and directory page.

Generally, there will be carousel pictures and thumbnails on the home page and directory page of the website, and the pictures are all connected together. For a picture with a specified page or orientation, the added alt tag text should be the title text of the linked page.

Second, the use of the content details page

When the picture on the detail page uses alt tag, you need to write the text into the related content of the picture. However, there are many alt tags on the details page, so there are often some problems. The website will give you an example:

1, keyword stacking: This is a mistake that many optimizers make. Because it is said that high keyword density is beneficial to optimization, alt tags of multiple keywords are added, resulting in high keyword density on the page, which will lead to search engines judging website cheating.

2. Too many alt descriptions: You can't use too many words when setting ALT tags, so search engines will not be able to identify keywords and grasp the key points of the website.

Third, unidentified graphics.

Search engines can't recognize pictures, so they add alt tags. If a picture is painted with flowers, but nothing is written when the alt tag is added, then the search engine only knows that it is a picture and will not capture the content on the picture.
