Generally speaking, search engines only read the text content, the image is not visible. At the same time, image files directly delay the page load time, if more than 20 seconds the site can not be loaded, users and search engines are very likely to leave your site. Therefore, unless the site content is mainly based on pictures, such as game site or image is essential, otherwise try to avoid using large pictures, not to use Pure Image production page (Splashpage).

Site image optimization of the core has two points. Increase the visual text description of the search engine and compress the file size of the image as much as possible while maintaining the image quality.

1.ALT Properties

There are aft attributes in each image img tag, such as: imgsrc= "Seo.com.cn/images/logo_about.gif" alt= "Hangzhou search engine Optimization service provider"/, the search engine will read this property to understand the image information. Therefore, it is best to have a text description in the ALT attribute of all illustrations, with the page keyword in it.

2. Text description

In addition to the ALT attribute text, consider the following methods to optimize the image directly so that it can be searched:

(1) Add a descriptive text containing the keyword above or below the picture.

(2) Add a heading title tag containing the keyword section in the code and add a text description below the picture.

(3) Add "more ..." links below or next to the picture, including keywords.

(4) Create some text pages that attract both the user and the search engine, attract the traffic to these pages, and then provide a text link to your picture page.

In short, the page should minimize decorative pictures as well as large pictures. The text in the aft attribute is less important to the search engine than the text of the text content.

3.GIF and Jpge image optimization

Aft attributes and text descriptions are only optimized for the text environment outside the image, and the following is a brief discussion of the optimization of the picture itself. The aim of the image file optimization is to minimize the file size in order to speed up the overall download speed of the page without affecting the image picture effect.

The

Web page picture format consists of GIF and JPGE in two forms. Generally speaking, GIF is suitable for line graph and enterprise logo; JPEG is suitable for the format of photo elements. By reducing the number of gie colors, reducing the size of the picture and reducing the resolution to reduce the file, you can use cascading style sheet to achieve optimization. The higher the Photoshop version, the more it works for network Graphics. In addition, the large picture cut into a number of small pictures to do different forms within the range of stitching, can also relatively faster download time.
