To give your site’s search engine ranking a massive boost, it’s imperative to optimize your images with proper image alt tags for SEO. A picture is not only worth a thousand words, but it can also be worth thousands of page views. When creating content, it’s important to keep this in mind. The human brain processes visuals 60,000 times faster than text. The alt text in the alt attribute of the image will help search engines understand the context of your picture.
What are alt tags?
Alt is shortcode acronym for “Alternative Text”. The ALT tag provides descriptive alternative text for when an image cannot be displayed. Google or the other search engine focus on the alt tag text and your on-page SEO optimization will complete only if you have proper alt tags with the images. According to the World Wide Web Consortium (W3C) – All non-text content that is presented to the user has a text alternative that serves its information correctly.
Unlike a human, a search engines spider does not have eyes. Spiders rely upon the alt text for categorising the content of a web page. This where our old friends ‘keywords’ come into play. I’ve always considered images on a page to be very good, as a good photo can hold humans attention for several seconds if they also get spiders attention; everyone is happy.
Importance of Image ALT Tag in SEO
Alt (alternative information) text was originally intended for the visually impaired but is also used by spiders to interpret what your content is more about. Your alt text description should be as accurate and descriptive as possible and contain your main keywords.
According to Google webmasters, it provides Google with useful information about the subject matter of the graphics. We use this information to help determine the best image to return for a user’s query.
Should I use both the TITLE and ALT tag?
In the HTML, the <IMG> element is the tag, ALT and TITLE are attributes of that tag. As mentioned, the image ALT tag will consist of primary information whereas the TITLE tag is used for providing supplementary information about the element.

Understand The Differences Between Image Alt Text And Image Titles
Title tags and alt tags are commonly confused with one another. While the alt tag is used by search engine crawlers to determine what your content is, title attributes provide extra information about the subject and are not crawled by bots. Therefore, image title tags aren’t as important to your site’s SEO, however, they do result in an improvement of accessibility online.
If an image is missing, the alt text will show in its place, however, the title text appears in a popup in certain browsers when a visitor hovers their mouse over the graphics.
