What Is Alt Text?

The alt attribute is a picture description consisting of several words, read by the web crawler when page is indexed. If user has disabled the graphics support function in the browser, then the contents of the tag will be displayed instead of the picture. The text for this attribute should not be excessively long.

The title attribute is a description for the visitor. If the user rests the mouse cursor on the picture for a couple of seconds, title attribute will appear. Usually, to fill this tag a detailed description of 1-2 proposals is used.

Why Do We Need Alt Tags?

No doubt, the graphic image will load correctly even if the image tags do not have img alt and title. But in this case, the possibilities of SEO images will remain unactivated. Having spent a bit of time creating an alternative description, webmaster will be able to:

  • transmit the necessary data to search robot;
  • attract new visitors;
  • increase readers’ loyalty.

Search engines examine uniqueness of graphic images, but they are not able to analyze their thematic identity. Therefore, if a webmaster wants a robot to categorize a picture, then it should make up a text for the alt tag.

In addition to the main search, Google and Yandex have “images” service. By creating optimized descriptions of image tags, webmaster increases the chances that Internet users will be able to come across his website using this service. In a result, traffic growth will be ensured.

Checking alt tags is important but not enough to get good SERP positions!

Keep in mind that there are different types of issues with images including pages having redirected images.

How to Use Tags in SEO Promotion?

To attract leads to promoted requests, webmaster has to make up descriptions using key phrases for alt and title. The text created for alt tag can look like this: “adjective + key phrase”. For the title attribute, it is recommended to create a complex sentence “adjective + key + addition”.

For instance, let’s take a key ” New York real estate “. For such key, you can draw a description alt “New York real estate luxury”, as well as the title “luxury real estate in Manhattan, New York.” An optimized description of image should contain such words as “photo”, “picture”.

Alt Text Best Practices

Eventually, image alt should be distinct yet in addition descriptive of the point of the webpage.

  • Be specific when you describing the image. Depict the picture, and be explicit. Use both the picture’s subject and setting to direct you.
  • Keep your alt text less than 125 characters. Screen-reading tools regularly quit perusing alt attribute at this point, cutting off wordy alt text at awkward moments.
  • Try not to begin alt text with “picture of…” or “Image of…” Jump directly into the picture’s description. Screen-reading tools (and Google, so far as that is concerned) will recognize it as an image from the article’s HTML source code.
  • Utilize your keywords, but sparingly. Possibly incorporate your article’s objective keyword if it’s effectively remembered for your alt text. If not, think about semantic keywords, or simply the most significant terms inside a longtail keyword.
  • Try not to pack your keyword into each and every picture’s alt attribute. In the event that your blog entry contains a series of body images, use your keyword once. Identify the picture you believe is generally illustrative of your topic, and assign it to your keyword.
