SEO specialists and digital marketers apply these techniques to increase organic traffic from visual search platforms.

1

Create a list of image attributes

Create a list called image_attributes with these exact items: 'alt text', 'file name', 'image size', 'image format', and 'structured data'.

SEO Fundamentals

# Create the list image_attributes with the specified items
# Your code here

Hint

Use square brackets to create a list and include all items as strings separated by commas.

2

Set minimum image resolution

Create a variable called min_resolution and set it to 800. This represents the minimum width or height in pixels recommended for visual search images.

SEO Fundamentals

image_attributes = ['alt text', 'file name', 'image size', 'image format', 'structured data']
# Set min_resolution to 800
# Your code here

Hint

Assign the number 800 directly to the variable min_resolution.

3

Filter images by resolution

Given a list called images where each image is a dictionary with a key 'size' holding a tuple of (width, height), create a new list called high_res_images that includes only images where width or height is greater than or equal to min_resolution. Use a for loop with variables image and check image['size'].

SEO Fundamentals

image_attributes = ['alt text', 'file name', 'image size', 'image format', 'structured data']
min_resolution = 800
images = [
    {'file name': 'shirt.jpg', 'size': (1024, 768)},
    {'file name': 'hat.png', 'size': (640, 480)},
    {'file name': 'shoes.jpeg', 'size': (800, 800)}
]
# Create high_res_images list with images meeting min_resolution
# Your code here

Hint

Use a for loop to check each image's width and height, then add qualifying images to high_res_images.

4

Add final summary statement

Create a string variable called summary with this exact text: 'Optimizing images with proper attributes and resolution improves visual search results.'

SEO Fundamentals

image_attributes = ['alt text', 'file name', 'image size', 'image format', 'structured data']
min_resolution = 800
images = [
    {'file name': 'shirt.jpg', 'size': (1024, 768)},
    {'file name': 'hat.png', 'size': (640, 480)},
    {'file name': 'shoes.jpeg', 'size': (800, 800)}
]
high_res_images = []
for image in images:
    width, height = image['size']
    if width >= min_resolution or height >= min_resolution:
        high_res_images.append(image)
# Add the summary string variable
# Your code here

Hint

Assign the exact text to the variable summary using quotes.
