Whether it is to do SEO or website construction, there are many people in the middle of the picture with the Alt attribute or the title attribute, and then how to use, very confused, not very clear. That Changsha SEO to say their function and how to use, so know when to use.

The ALT attribute acts as a comment on a picture, now the search engine on the image reading function is limited, when we want to tell the search engine this picture is what the time will use the ALT attribute, at the same time for SEO is also very good, you can appropriately increase the density of a keyword (avoid keyword piling). In fact, when you use some webmaster tools, you will be prompted how many pictures on the front page did not add alt attribute. Baidu statistics of the recent SEO recommendations inside will also detect this item, it is conceivable that the ALT attribute to the role of SEO is very large.

Title attribute, when the mouse is placed on the picture will display the title attribute inside the text, the official title attribute definition is the role of annotation picture link, but when a picture has no link, we also need to use the title attribute, this is related to the user experience. Changsha SEO I think the title attribute is born for the user experience, for SEO no effect, some people said he can also increase the keyword density, I disagree, because the search engine does not recognize this attribute, from Baidu statistics SEO suggestions can be seen. When will the title tag be used? When the picture has a link to use, so that when the user points to this picture will display text, the user can be based on the text to determine whether the load page is their own interest, reduce the load of unwanted pages. When there is no link in the picture, and there is no text title next to the picture and the text title is very long, we also use the Title property to tell the user what the picture is. The title attribute is not wrong for the user experience.

Here, the two pictures of the role of the properties should be very clear, the ALT attribute to facilitate the role of SEO, title properties to enhance the user experience role. When will the distinction be used? Alt Property There is no doubt that the ALT attribute is used wherever there is a picture; The Title property is not available in one case, that is, there is no link to the picture, and there is already text on the side of the picture, so don't bother to tell the user what the picture means.

About these two attributes on here, now is more than nine o'clock in the evening, wash to prepare to see "The Emperor Imperial Concubine", this TV is good, we have time to see, I hope you continue to support Chen Heqing SEO blog.
