How to apply image keyphrases to optimize blog posts and precautions

What are image keyphrases?

Image keyphrases refer to the text information embedded within the image file itself and the descriptive text associated with the image. Since search engines cannot directly understand image files, they rely on image keyphrases to grasp the content of the image and reflect it in search results. The main elements of image keyphrases are as follows:

• Image Filename: The name used to save the image file.
• Alt Text (Alternative Text): Text that describes the image content for users when the image fails to load or for those using screen readers.
• Caption: Text that provides additional explanation below the image.
• Surrounding Text: The body text around the image also helps search engines understand the image’s context.

How to Apply Image Keyphrases:

Now, let’s delve into how to apply image keyphrases for each element to optimize your blog posts:

1. Optimizing Image Filenames:

• Use Clear and Descriptive Keywords: Include keywords that clearly indicate the image’s content when naming the file. For example, “Jeju-Island-Sunrise-Peak-Scenery.jpg” is much better than “image123.jpg”.
• Use Hyphens (-) Instead of Spaces: Separate words in the filename with hyphens, as search engines recognize hyphens as word separators. For example, “Jeju-Island-Best-Black-Pork-Restaurant.jpg”.
• Use Lowercase: It’s generally best practice to use lowercase for filenames, as some server environments are case-sensitive.
• Avoid Special Characters and Unnecessary Words: Do not use special characters or unnecessary particles and conjunctions in the filename for a cleaner and search engine-friendly approach.

2. Writing Alt Text:

• Summarize the Core Content of the Image: Briefly and clearly explain the most important information conveyed by the image. This effectively communicates the image’s content to both screen reader users and search engines.
• Include Relevant Keywords Naturally: Incorporate keywords highly relevant to your blog post naturally. Be cautious not to overstuff keywords, as this can have a negative impact.
• Provide Specific Descriptions: Offer concrete descriptions rather than abstract expressions. For example, instead of “beautiful scenery,” use “blue sea and magnificent Seongsan Ilchulbong.”
• Write in Sentence Form: It’s better to write in complete sentences to clearly convey the meaning rather than just listing keywords.
• Crucial When Image Replaces Text: If the image contains important information that replaces text, the alt text should be even more detailed and accurate.

3. Utilizing Captions:

• Provide Additional Information About the Image: Captions are useful for supplementing the image’s content or providing additional context.
• Enhance Reader Understanding: Through captions, readers can more easily understand the image’s meaning and grasp the blog post’s content more deeply.
• Reiterate Main Keywords or Use Related Keywords: You can mention the main keywords used in the body text again or use related keywords to enhance search engine optimization. However, be careful not to disrupt the natural flow.

4. Leveraging Surrounding Text:

• Write Content Related to the Image: The body text around the image serves as an important clue for search engines to understand the context in which the image is used. Therefore, it’s good practice to write content closely related to the image.
• Maintain Consistency: Ensure that the content of the image keyphrases and the surrounding text is consistent, helping search engines highly value the relevance between the image and the content.

Important Considerations When Applying Image Keyphrases:

• Avoid Excessive Keyword Usage: Over-repeating keywords in all image keyphrases can negatively impact search engine optimization. It’s important to write natural and meaningful text.
• Use Keyphrases Relevant to Each Image’s Content: Using the same keyphrases for all images is not effective. Apply the keyphrases most relevant to each image’s content.
• Consider Accessibility: Alt text is a crucial element in enhancing content accessibility for visually impaired users. Rather than solely focusing on search engine optimization, provide descriptions for all users.

Optimizing image keyphrases is an important factor in improving the overall SEO effectiveness of your blog posts. By referring to the methods explained above, make sure to apply them meticulously each time you upload images to your blog. Consistent effort will help you achieve higher visibility in search engines and attract more traffic.
