💼 Career

Understanding crawl budget and pagination is essential for SEO roles, digital marketing, and website management to ensure efficient indexing and better search visibility.

1

Create a list of paginated URLs

Create a list called page_urls containing these exact URLs as strings: 'https://example.com/articles?page=1', 'https://example.com/articles?page=2', 'https://example.com/articles?page=3', 'https://example.com/articles?page=4', and 'https://example.com/articles?page=5'.

SEO Fundamentals

# Create the list of page URLs
# Your code here

Hint

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

2

Set the maximum crawlable pages

Create a variable called max_crawl_pages and set it to the integer 3 to limit how many pages search engines should crawl.

SEO Fundamentals

page_urls = [
    'https://example.com/articles?page=1',
    'https://example.com/articles?page=2',
    'https://example.com/articles?page=3',
    'https://example.com/articles?page=4',
    'https://example.com/articles?page=5'
]
# Set the max_crawl_pages variable
# Your code here

Hint

Assign the number 3 to the variable max_crawl_pages.

3

Generate pagination links up to the crawl limit

Use a for loop with the variable url to iterate over the first max_crawl_pages items in page_urls. Inside the loop, create a list called crawlable_links and add each url to it.

SEO Fundamentals

page_urls = [
    'https://example.com/articles?page=1',
    'https://example.com/articles?page=2',
    'https://example.com/articles?page=3',
    'https://example.com/articles?page=4',
    'https://example.com/articles?page=5'
]
max_crawl_pages = 3
crawlable_links = []
# Use a for loop to add URLs up to max_crawl_pages to crawlable_links
# Your code here

Hint

Use slicing page_urls[:max_crawl_pages] to get only the first pages.

4

Add a meta tag to block indexing beyond allowed pages

Create a string variable called robots_meta_tag and set it to the exact value '<meta name="robots" content="noindex, follow">' to instruct search engines not to index pages beyond the crawl limit but still follow links.

SEO Fundamentals

page_urls = [
    'https://example.com/articles?page=1',
    'https://example.com/articles?page=2',
    'https://example.com/articles?page=3',
    'https://example.com/articles?page=4',
    'https://example.com/articles?page=5'
]
max_crawl_pages = 3
crawlable_links = []
for url in page_urls[:max_crawl_pages]:
    crawlable_links.append(url)
# Add the robots meta tag string
# Your code here

Hint

Use single quotes outside and double quotes inside the string for the meta tag.

Practice

1. What is the main purpose of pagination on a website?

easy

A. To split content into smaller, manageable pages for users and search engines

B. To increase the total number of pages regardless of content

C. To hide content from search engines

D. To slow down website loading speed

Solution

1. Step 1: Understand pagination purpose and evaluate options

   Pagination divides large content into smaller pages to improve user experience and search engine crawling. Only To split content into smaller, manageable pages for users and search engines correctly describes this purpose; others are incorrect or harmful.

2. Final Answer:

   To split content into smaller, manageable pages for users and search engines -> Option A

3. Quick Check:

   Pagination purpose = split content [OK]

Hint: Pagination means breaking content into pages for easier reading [OK]

Common Mistakes:

• Thinking pagination hides content
• Believing pagination increases page count without reason
• Assuming pagination slows site down

2. Which HTML attribute is used to indicate the relationship between paginated pages for SEO?

easy

A. rel="nofollow"

B. rel="alternate"

C. rel="canonical"

D. rel="prev" and rel="next"

Solution

1. Step 1: Identify attributes for pagination and compare with other attributes

   For SEO, rel="prev" and rel="next" link tags show page order in pagination. rel="nofollow" blocks crawling, rel="canonical" points to main page, rel="alternate" is for language versions.

2. Final Answer:

   rel="prev" and rel="next" -> Option D

3. Quick Check:

   Pagination links = rel="prev" and rel="next" [OK]

Hint: Use rel="prev" and rel="next" for page order in pagination [OK]

Common Mistakes:

• Confusing rel="canonical" with pagination links
• Using rel="nofollow" to control pagination
• Ignoring rel attributes for paginated pages

3. Consider a website with 100 paginated product pages. Which strategy best optimizes crawl budget?

medium

A. Use rel="prev" and rel="next" links and allow crawling

B. Block all paginated pages using robots.txt

C. No pagination, load all products on one page

D. Use noindex on the first page only

Solution

1. Step 1: Understand crawl budget and pagination and evaluate options

   Crawl budget is limited; using rel="prev" and rel="next" helps search engines crawl paginated pages efficiently. Blocking all pages wastes content; loading all on one page harms speed; noindex on first page hides important content. Use rel="prev" and rel="next" links and allow crawling is best.

2. Final Answer:

   Use rel="prev" and rel="next" links and allow crawling -> Option A

3. Quick Check:

   Crawl budget optimized by rel links and crawling [OK]

Hint: Keep paginated pages crawlable with rel="prev"/"next" [OK]

Common Mistakes:

• Blocking paginated pages completely
• Putting noindex on main pages
• Loading all content on one page causing slow load

4. A website uses rel="canonical" on all paginated pages pointing to the first page. What is the likely SEO issue?

medium

A. It improves crawl budget by focusing on the first page only

B. Search engines may ignore all pages except the first, losing content visibility

C. It correctly signals page order for pagination

D. It prevents duplicate content issues perfectly

Solution

1. Step 1: Understand canonical use in pagination and identify SEO impact

   Using rel="canonical" on all pages pointing to the first page tells search engines to treat them as duplicates of the first page. This causes search engines to ignore other pages, losing their unique content and reducing visibility.

2. Final Answer:

   Search engines may ignore all pages except the first, losing content visibility -> Option B

3. Quick Check:

   Wrong canonical use hides paginated pages [OK]

Hint: Don't canonicalize all pages to first in pagination [OK]

Common Mistakes:

• Assuming canonical fixes pagination order
• Thinking it improves crawl budget positively
• Believing it prevents all duplicate content issues

5. You manage a large blog with hundreds of paginated archive pages. To optimize crawl budget and improve SEO, which combined approach is best?

hard

A. Block all archive pages in robots.txt and rely on sitemap only

B. Canonicalize all archive pages to the homepage

C. Use rel="prev"/"next" links, noindex pages beyond page 5, and ensure fast page load

D. Load all posts on one infinite scroll page without pagination

Solution

1. Step 1: Combine pagination and crawl budget strategies and evaluate other options

   Using rel="prev" and rel="next" helps search engines understand page order. Noindexing deep pages reduces crawl waste. Fast loading improves user experience and crawl efficiency. Blocking all pages hides content, canonicalizing to homepage loses page value, infinite scroll without pagination harms crawl and UX.

2. Final Answer:

   Use rel="prev"/"next" links, noindex pages beyond page 5, and ensure fast page load -> Option C

3. Quick Check:

   Combine rel links, selective noindex, and speed for best SEO [OK]

Hint: Combine rel links, selective noindex, and speed for crawl budget [OK]

Common Mistakes:

• Blocking all archive pages
• Canonicalizing all pages to homepage
• Ignoring page speed and crawl limits
