More Than Decoration! Why You MUST Optimize Images for SEO
Key Takeaways
- The images on your website are not just decoration; they are crucial assets for your overall SEO success.
- Properly optimizing your images is essential for four massive reasons:
- Page Speed: Huge, unoptimized images are often the single biggest cause of a slow-loading website. Slow sites frustrate users and are disliked by Google.
- User Engagement: Relevant, high-quality images grab attention and keep people on your page longer, which is a powerful positive signal to Google.
- Image Search Traffic: People use Google Images constantly. Optimized images can rank in image search results, bringing you an extra source of targeted traffic.
- Context: Images provide extra clues to Google, helping it better understand what your page is about and reinforcing your topic's relevance.
Describe Your Images Alt Text for Accessibility & SEO
Key Takeaways
- How does Google or a visually impaired person using a screen reader know what's in your image? The answer is Alt Text.
- Alt text is a short, written description of an image that you add to the image's code. It serves two vital purposes:
- Accessibility: This is its primary job. Screen readers read the alt text aloud, allowing visually impaired users to understand the image's content and making the web usable for everyone.
- SEO: Search engine crawlers can't "see" images, so they rely heavily on alt text to understand an image's content and its relevance to the surrounding text.
Actionable Items
Writing Good Alt Text
- Be Descriptive, Yet Concise: Clearly and briefly describe what is in the image. Think: "How would I describe this to someone over the phone?"
- Include Keywords Naturally: If your target keyword is genuinely relevant to the image (e.g., the image is a "blue widget" and your keyword is "blue widget"), then include it.
- Do NOT Keyword Stuff: Never force keywords where they don't belong. This is bad practice.
Alt Text: Bad vs. Good
| Example | Alt Text |
|---|---|
| Bad Example | alt="image seo keyword buy now cheap" |
| Good Example | alt="Smiling woman holding a blue widget" |
Naming Your Images Simple File Name Best Practices
Key Takeaways
- Using generic, default file names like
IMG_5872.JPGis a missed SEO opportunity. - The actual file name you give an image before you upload it provides another important clue to Google about the image's content.
Actionable Items
Naming Your Image Files
- Be Descriptive: Use file names that accurately describe the image and include relevant keywords.
- Use Hyphens: Separate words with hyphens, not underscores or spaces.
- Keep it Clear: Aim for short and easy-to-understand file names.
File Naming: Instead of vs. Use
| Example | File Name |
|---|---|
| Instead of | DSC00567.jpg |
| Use | blue-stainless-steel-widget.jpg |
Making Videos Work for SEO Embedding & Optimization
Key Takeaways
- Embedding relevant videos directly into your content is a powerful way to boost user engagement.
Why embed videos?
- They explain complex topics visually and add variety to your page.
- They significantly increase Dwell Time (how long a user stays on your page), which is a strong positive signal to Google.
Best Practice: Don't upload large video files directly to your website server. Instead, upload them to a platform like YouTube or Vimeo and use their "embed code" to display the video on your page.
Video SEO: To help your videos get discovered in search, you must optimize them on their host platform (like YouTube).
- Compelling Title: Grab attention and include your main keyword.
- Detailed Description: Explain what the video is about, using keywords naturally and adding helpful links.
- Relevant Tags: Add keywords and topics that describe your video to help YouTube categorize it.
Well-optimized YouTube videos have a much better chance of appearing in Google's main search results, driving more traffic.
Quick Tips! Finding Videos & Using Canva
Key Takeaways
- You don't always have to create your own videos. Embedding a relevant, high-quality video made by someone else can still boost engagement.
- To find videos: Simply search on YouTube using keywords that are directly related to your page's topic. Look for a high-quality, credible video, grab the embed code under the "Share" button, and paste it into your page editor.
You also don't need to be a professional designer to create great images.
A user-friendly tool like Canva makes it easy to handle essential image tasks. You can use its free version to:
- Resize images to the exact dimensions you need.
- Add text overlays and captions.
- Create simple graphics for your site or social media using templates.
- Export images in web-friendly formats like JPG and PNG.
Where This Leads
- We've now covered how to optimize all the content on our pages, from text to images and video. But what about building authority beyond our own website? It's time to venture into the world of Off-Page SEO.
