Over a decade ago, in 2010, Google announced that relevant images on web pages would be considered a ranking factor. Since then, their algorithms have evolved, enabling Google bots to understand and index video content starting in 2014. Despite the ever-changing algorithms, the influence of images and videos on website SEO and ranking is the same.
In this article, we will delve into the significance of visual content in SEO and provide valuable insights on optimizing images and videos to enhance search engine performance in the present day.
The role of visual content in SEO
Visual content plays a pivotal role in user engagement and website ranking. In today's digital landscape, where attention spans are shorter, and users are constantly bombarded with information, visuals have become a powerful tool to capture attention and convey messages more effectively. Empowering your content with high-quality images helps it become more noticeable and increases the likelihood of social sharing. And video content accounts for over 80% of all internet traffic and is the most powerful type of content nowadays.
With the continuous growth of visual-centric platforms and users' preferences for engaging visuals, incorporating optimized images and videos into your SEO strategy has become more important than ever.
Search engines themselves have recognized the value of visual content in enhancing user experience. Google, in particular, has evolved its algorithms to provide a more diverse and visually appealing search experience. This has led to the integration of images, videos, and other multimedia content into search results, making it even more crucial for websites to optimize their visual assets for search engine visibility.
SEO optimizing images and video content goes beyond mere aesthetics. It directly impacts user experience, social sharing, and ultimately, your website's visibility in search results, making it a crucial component of successful SEO strategies.
Optimizing images for search engines
Let’s start with the images and how you can optimize them to improve your website SEO and position on SERP. Multiple factors are important for image optimization:
- file name
- alt text
Let’s look at them in detail.
Image choice and format
To optimize images for SEO, it is essential to choose relevant and high-quality visuals that align with your content. Additionally, selecting the appropriate image file formats is not less important since it influences the image quality and loading speed.
- JPEG. This format is ideal for photographs and complex images with many colors. It offers good compression while maintaining image quality.
- PNG. PNG is suitable for images with simple graphics, icons, or illustrations with transparency. It supports lossless compression, preserving image quality without sacrificing details.
- WebP. WebP is an image format developed by Google that offers superior compression and image quality compared to traditional formats. It provides faster loading times and supports transparency and animations. However, it's worth noting that not all browsers and image editing software fully support the WebP format.
Image compression and file size
Optimizing image size and reducing file size is crucial for improving website speed and positioning on SERPs. Balancing image quality and file size is vital to ensure fast-loading pages without compromising visual appeal. The recommended image size is between 10 KB and 5 MB.
Image file name and alt text
Alt text, also known as alternative text, is used to provide information about an image for users who may have difficulty viewing it, such as those who are visually impaired or using assistive technologies. Crawling bots utilize image file names and SEO alt text to comprehend the context and relevance of your visual content. When writing image alt text for better SEO, be descriptive and concise, conveying essential information and relevant details. Avoid keyword stuffing and omit redundant information. Additionally, consider the context and tailor the alt text to align with the webpage's message and intention.
Caption and description
Utilizing captions and SEO descriptions for your images can provide additional context to both users and search engines. Craft concise and informative captions that accurately describe the image and incorporate relevant keywords where appropriate. In most cases, a caption should consist of a few words or a short sentence. Aim to keep the description around 125 characters, ensuring it is easily scannable and doesn't take up too much space on the page or screen.
Optimizing videos for search engines
Now, let's move on to video content. The process of enhancing videos is quite similar to optimizing images. In this case, it's important to consider factors such as file size and format, as well as optimize the video title, description, and tags. However, when working on video SEO optimization, it's crucial to also take into account the platform where you plan to publish the video, the inclusion of a video transcript, and the addition of closed captions.
Video file optimization
Just like with images, it is important to choose the appropriate video format and reduce file size for faster loading while maintaining video quality. In terms of video format for search engine optimization, the preferred choice is generally MP4 (MPEG-4). MP4 is widely supported by various devices, browsers, and platforms, ensuring accessibility to a larger audience.
Video title, description, and tags
Another step that is similar to optimizing images is managing video metadata, which includes the title, description, and tags. This is crucial for search engine indexing and ranking. Craft compelling titles, informative descriptions, and relevant tags to enhance the visibility of your videos in search results.
Video hosting platform
There are various ways to implement video content on your website, including publishing it on hosting platforms like YouTube or Vimeo. These platforms prioritize SEO and can enhance the visibility of your video content in search engine results. Additionally, they offer the convenience of embedding videos on your website, alleviating the need for additional server load.
Video transcriptions and closed captions
Providing video transcriptions and closed captions not only makes your content accessible to a wider audience, including individuals with hearing impairments, but it also has a positive impact on SEO. By including video transcriptions and closed captions, search engines can crawl and index the text, increasing the likelihood of your videos appearing in relevant search queries. This improves the overall discoverability and reaches of your video content while also enhancing the user experience for those who prefer or require captions or transcriptions.
As you can see, visual content holds significant importance in SEO, and optimizing images and videos is crucial for enhancing search engine performance. Over the years, search engine algorithms have recognized the value of visual elements, leading to their integration into search results. By optimizing images and videos, selecting appropriate formats, compressing file sizes, and providing descriptive metadata, you can improve your website visibility, user experience, and social sharing.
