What is Alt Tag?
The text to be set in the Alt tag is "text to be displayed instead when the image is not displayed." It is important to set a text suitable for that image in the context, not just an explanation of an image.
Look at the site with a text browser and check if there is an unnatural place. Setting ALT tags makes it easier to hit image search. ( * Please note that if you set a wording that has nothing to do with the image or forcibly packing the keywords, it will be a violation of Google guidelines.)
Handling by search engine search engine
There are multiple patterns as shown below for the treatment of Alt attributes by search engines.
- The text set in the ALT tag is recognized, but it is not used to add points.
- The text set in the Alt tag is also treated in the same way as a normal text
- A treated in the Alt tag only in the same way as an anchor textbook
( * In the past, SEO companies pack keywords, etc. in the past.
necessary to set an ALT tag to prevent the evaluation of the search engine by force.
Precautions when using Alt tags
When you actually set the Alt tag on the site, you may want to check the following three points.
(1) Is the file name of the image related to the contents of the image?
(2) Is the ALT attribute in the image a description that humans can read and understand?
③ Is the text content on the HTML page and the text around the image related to the image?
The above three points are particularly important, but the following points are also important.
- Specify the empty attribute value "ALT =" "for images and images used for spacers as meaningless markers.
- Do not use the image as much as possible, and use CSS for character decoration.
- When using an image for the content of the element, set the same content as the anchor textbook to be set if it is not an image.
These are all measures for "search engines to see the same information as the user".
Even if it is a very easy -to -understand site for users, it would be a waste if the search engine did not understand correctly.
In the future, it is necessary to set the Alt tag, so be sure to set it properly.
