The value of content for SEO is invaluable, as it leads users to a given website. In this area, images and iconography are often overlooked, even though they enhance the site's appearance and are often a source of knowledge in their own right.
Moreover, they are crucial for the website positioning process itself . Graphics and photos are an important element of every website: blog, e-commerce, or social media. Content that is concise and relevant significantly impacts SEO optimization and improves a website's visibility in search engines.
However, it's difficult to imagine a text-based website without images and iconography. These graphic elements are crucial to a website's SEO, so it's crucial to ensure effective image optimization through alt and title attributes.
Website positioning – key activities
If you want your website to thrive in the depths of the internet, you need to ensure proper SEO optimization . The number of website users who use computers, smartphones, and tablets to browse hundreds of websites daily, searching for information, making purchases, and strengthening social connections, is growing.

Modern users are becoming increasingly demanding, making it harder to satisfy them and, consequently, keep them on a given website. Competition in every online space is constantly growing, so website positioning should be a priority if you don't want to be left behind. That's why SEO activities are so important ; if performed consistently and diligently, they will yield visible results over time.
These practices should begin primarily with on-site optimization. Appropriate headlines, a user-friendly URL, internal linking, page load speed, audience definition, the use of relevant keywords, and, of course, substantive content enriched with images. All these aspects positively impact branding, website attractiveness, and its content value.
These actions ultimately contribute to increasing the website's visibility in SERPs. Google's crawlers scan content, but they don't see images unless they have alt and title attributes.
Images on a page must be well-labeled and described to inform search engine crawlers about their content. Well-optimized images will be indexed and have a positive impact on the page's SEO.
ALT attribute – what is it?
In other words, an alternative description of an image, which is located in the HTML code of the page.
The key here is the naming of the alt attribute, i.e. the alternative description.
If the image is not loaded on the page, the completed alt text is still visible to Google robots and is indexed. Interestingly, it is the alt text attribute that is read by programs used by people with severe visual impairments or blindness.
All alt text descriptions on a website can be displayed using a Web Developer plugin installed for a given browser. This way, you can easily verify whether a page has alt attributes.
What content should the alt attribute contain?
Alt text is read by programs for the blind and by web crawlers. For these reasons, the alt attribute should specify the actual image content. However, in the age of SEO optimization, this rule has changed somewhat.
The description should provide information about what's on the site and what content can be accessed from it. However, as with meta tags, these tags can't be phrases written after commas, but rather specific search terms or links containing keywords—though they still relate to the image's content.
What is the title attribute?
This is simply the image title, visible when you hover over it (if the image includes an alternative description). It's also called supporting text and is slightly less important than the alt attribute.
The photo title can include a description of the image or a summary of the page's content. For example, it could be titled "Alt and title – effective SEO image optimization." A well-titled photo positively impacts the page's graphical positioning, which can lead to increased post reach and page clicks.
On-page image optimization
Smaller is better – follow this rule when it comes to image sizes on your website. A smaller image is better for the website because it will load faster. A website that loads too slowly leads to a high bounce rate. Page speed is important for users, but also for Google's crawlers.
As a rule, a photo on a website should be no larger than 100 KB. Content is crucial when optimizing alt and title attributes. As with all content on the website, the content in photos should be unique, especially within a single page or subpage.
A differentiated alt and title description improves the way Google crawls read your page. This will translate into higher search engine rankings for specific keywords.
Image and iconography as an important medium for transmitting information
Not only optimization, but also the "content" of the image is crucial for the user. Images enrich the wall of text, increasing the attractiveness and clarity of the website. Good photos with properly described alt and title attributes – especially on storefronts – can have a decisive influence on whether a customer purchases a given product.
Recently, iconography has become very popular, and it's worth using it in specialized texts and on social media . Such images convey a clear message to the reader, often condensing information related to the page's content. Sometimes, such an image serves as a concrete knowledge base for the user, which is why they quickly rank in Google Images.
A properly optimized website has the potential to rank higher in search results for specific keywords. It's important to ensure high-quality activities on the website from the very beginning.
Website positioning is a time-consuming task that requires discipline and consistency in actions, which also includes optimizing images with alt and title attributes.
FAQs about ALT and TITLE
The ALT attribute is a description hidden in the HTML code of exactly what's in an image. It displays on the screen when the browser is unable to load the image for technical reasons. It's also read by screen readers for the blind and visually impaired, ensuring the website's digital accessibility.
Huge. Google's crawlers can't "see" images, so they rely on alt text to understand what the file represents. A well-optimized ALT tag helps your website appear in Google Images search results. Additionally, if the image is also a hyperlink, the ALT attribute acts as anchor text.
The TITLE attribute (image title) is additional information that appears as a small tooltip when a user hovers over an image. Unlike ALT, the TITLE attribute is marginal to Google's algorithms and SEO, but it is a useful element for improving user experience (UX).
A good ALT should accurately, concisely, and naturally describe what's actually visible in the image (usually a few to a dozen words are enough). It's worth incorporating relevant keywords into it, but you should absolutely avoid keyword stuffing, which can be treated as spam by search engines.
No. Alt text is essential for product photos, infographics, and images that convey specific informational value. However, for purely decorative graphics (e.g., decorative backgrounds, dots, dividers, interface elements), this attribute should be left empty in the code (written as alt="") to avoid informational chaos for robots and screen readers.
