  5. How to write good Alt text

    We have already talked about what is alt text and the importance of SEO friendly Alt Text with the images on your webpage. They make the website more accessible and efficient; however, like there are best practices for writing the SEO-friendly content and choosing the right keywords, similarly, there are several things one should keep while writing Alt Text.
    The text should not look compulsive or unrequired; rather, it should be written so that it is accurate and adds value to the website. A poorly written Alt Text serves no purpose and can increase the confusion on the concept or idea you are trying to convey through your webpage or image. The appropriate Alt Text is related to the image and deciphers its purpose, intent, and definition without beating around the bush.
    Even though every individual may interpret an image differently and come up with Alt text descriptions per their understanding, it is always beneficial to follow the best practices.
    ·         Alt text should be similar to the content and the purposes of the image. Ensure that you understand the idea, its source, and the location where it will be used; this helps you come up with the most relevant, understandable, and accurate alt text description.
    ·         As mentioned above, ‘Be Specific’. Again, do not beat around the bush and use text as fillers. There is no need to fluff the content to increase words or write the content which is not relevant. Alt Text should be precise, crisp, and short.
    ·         Don’t Be repetitive: One should keep in mind that if you are going to use redundant content and talk about the same thing in different ways, it is not going to add any value to your image. 
    ·         Don’t Use Self Descriptive terms: This is a master tip when writing alt text. As we discussed that Alt text should be precise, and short writing terms like Image of a Horse or Picture of a white horse would look irrelevant.

  6. Some Examples of What is Alt Text and How to Write it Effectively

    Let us understand the impact of good alt text in an image with a simple example of a floral ladies’ dress. While it is not a great idea to write a picture of the lady’s clothing in the alt text, it is descriptive from the image name itself, and obviously, we are using an image, so using the word picture is not required. 
    Bad: <img src= “Floraldress.png” alt=“picture of ladies dress”>
    Using the alt text as ladies’ dress is okay as it describes the image and helps the screen readers to inform the users what the image is about. 
    Okay: <img src= “Floraldress.png” alt=“ladies dress”>
    Good: <img src= “Floraldress.png” alt=“Floral ladies dress”>
    Using a more descriptive text like a floral lady’s dress helps the search engine crawlers to pick the image as the reader is more descriptive yet crisp. 
    Best: <img src= “Floraldress.png” alt=“Floral ladies dress with flares”>
    Using the text like Floral lady’s dress with flares adds more details to the image and makes it relevant to the users searching for a dress with that style and design.

  7. Avoid Keyword Stuffing

    When writing Alt Text, make sure that you do not unnecessarily stuff the SEO keywords in the Alt Text. It is ideal to use the keyword in the appropriate density and ensure that it is used logically in the text. Many writers and content creators make a mistake of stuffing the keyword to attain the keyword density goal without ensuring that the word is used logically in the sentence and makes sense to the overall content.
    Be it SEO blogs, articles, or alt description; one should keep in mind that the keywords and search terms should be used logically. One should focus on the quality of the content and provide the context of the image.
    There is no point in using the keyword to write alt text that makes no sense. Search algorithms are now smarter than ever and would not dock all the poorly written alt text images and may not even show them in the search results.
    On the other hand, if your pictures have well-defined, pertinent, and logically written alt text, you have high chances of emerging in search results and garner valuable organic traffic. If you can use the keywords smartly in the alt description, it’s an added advantage.

  8. Finding Images with Missing Alt Text

    If there are images on your website which do not have a clearly defined alt text, then your pictures may lose the purpose and not add much value in the SEO perspective.
    The search crawlers may not catch them, and thus you miss out on a considerably good chance of getting the high organic traffic to your website. Having a title and alt text can help your images rank higher and boost your SEO efforts considerably. 
    It is not an easy task to find the images with missing text within your website or page. You can do that manually; however, it is going to be a very cumbersome job altogether.
    There are several SEO tools available in the market that help find the images with missing alt text, and these tools track the images more extensive than the size of 1 by 1 pixel and suggest you add alt text.
