💼 Career

Understanding crawl budget helps digital marketers and SEO professionals manage large websites efficiently and improve organic traffic.

1

Create a list of URLs with priority

Create a list called urls with these exact entries as tuples: ("/home", 10), ("/about", 5), ("/blog/post1", 8), ("/blog/post2", 3), ("/contact", 6).

SEO Fundamentals

# Create the list called urls with the given tuples
# Your code here

Hint

Use a list of tuples where each tuple has the URL string and its priority number.

2

Set a priority threshold

Create a variable called priority_threshold and set it to 6 to filter URLs with priority above this value.

SEO Fundamentals

urls = [
    ("/home", 10),
    ("/about", 5),
    ("/blog/post1", 8),
    ("/blog/post2", 3),
    ("/contact", 6)
]
# Create priority_threshold variable and set it to 6
# Your code here

Hint

This variable helps decide which URLs are important enough to crawl.

3

Select URLs above the priority threshold

Create a list called high_priority_urls using a for loop with variables url and priority to iterate over urls. Add only URLs with priority greater than priority_threshold.

SEO Fundamentals

urls = [
    ("/home", 10),
    ("/about", 5),
    ("/blog/post1", 8),
    ("/blog/post2", 3),
    ("/contact", 6)
]
priority_threshold = 6
# Create high_priority_urls list with URLs having priority > priority_threshold
# Your code here

Hint

Use a loop to check each URL's priority and add only the important ones to the new list.

4

Add rule to block low priority URLs

Create a list called blocked_urls with URLs from urls where priority is less than or equal to priority_threshold using a for loop with variables url and priority.

SEO Fundamentals

urls = [
    ("/home", 10),
    ("/about", 5),
    ("/blog/post1", 8),
    ("/blog/post2", 3),
    ("/contact", 6)
]
priority_threshold = 6

high_priority_urls = []
for url, priority in urls:
    if priority > priority_threshold:
        high_priority_urls.append(url)

# Create blocked_urls list with URLs having priority <= priority_threshold
# Your code here

Hint

This list will help you block less important pages from being crawled.

Practice

1. What is the main goal of crawl budget optimization in SEO?

easy

A. To speed up the website loading time

B. To increase the number of ads shown on a website

C. To help search engines focus on important pages of a website

D. To improve the website's color scheme

Solution

1. Step 1: Understand crawl budget concept

   Crawl budget is the number of pages a search engine crawls on your site within a given time.

2. Step 2: Identify the goal of optimization

   Optimizing crawl budget means helping search engines spend time on your best, most important pages.

3. Final Answer:

   To help search engines focus on important pages of a website -> Option C

4. Quick Check:

   Crawl budget optimization = focus on important pages [OK]

Hint: Focus on what crawl budget controls: crawling important pages [OK]

Common Mistakes:

• Confusing crawl budget with website speed
• Thinking it increases ads or visual design
• Assuming it controls user experience directly

2. Which of the following is a correct way to block unimportant pages from being crawled?

easy

A. Using a sitemap to list unimportant pages

B. Removing the pages from the website completely

C. Increasing the page load speed

D. Adding those pages to robots.txt with Disallow directive

Solution

1. Step 1: Identify method to block pages from crawling

   Robots.txt file uses Disallow to tell search engines not to crawl certain pages.

2. Step 2: Check other options

   Sitemaps list pages to crawl, not block; removing pages is extreme; speed does not block crawling.

3. Final Answer:

   Adding those pages to robots.txt with Disallow directive -> Option D

4. Quick Check:

   Block pages = robots.txt Disallow [OK]

Hint: Remember: robots.txt Disallow blocks, sitemap lists pages [OK]

Common Mistakes:

• Confusing sitemap with blocking tool
• Thinking page speed blocks crawling
• Assuming deleting pages is the only way

3. If a website has many low-value pages and no robots.txt file, what is the likely effect on crawl budget?

medium

A. Search engines may waste crawl budget on low-value pages

B. Search engines will crawl mostly important pages only

C. Crawl budget will automatically increase

D. Search engines will ignore the website

Solution

1. Step 1: Understand absence of robots.txt impact

   Without robots.txt, search engines can crawl all pages, including low-value ones.

2. Step 2: Effect on crawl budget

   Crawl budget may be wasted on unimportant pages, reducing focus on valuable content.

3. Final Answer:

   Search engines may waste crawl budget on low-value pages -> Option A

4. Quick Check:

   No robots.txt + many low-value pages = wasted crawl budget [OK]

Hint: No robots.txt means no crawl blocking, so waste happens [OK]

Common Mistakes:

• Assuming crawl budget increases automatically
• Thinking search engines ignore sites without robots.txt
• Believing search engines only crawl important pages by default

4. A website owner added Disallow: /private/ in robots.txt but search engines still crawl those pages. What is the likely error?

medium

A. The pages are blocked by meta tags

B. The robots.txt file is not placed in the website root directory

C. The website has too many pages

D. The sitemap file is missing

Solution

1. Step 1: Check robots.txt placement

   Robots.txt must be in the root folder (e.g., example.com/robots.txt) to be effective.

2. Step 2: Understand other options

   Sitemap absence doesn't cause ignoring robots.txt; too many pages don't override rules; meta tags block differently.

3. Final Answer:

   The robots.txt file is not placed in the website root directory -> Option B

4. Quick Check:

   Robots.txt must be in root to block pages [OK]

Hint: Robots.txt must be at root, else rules won't apply [OK]

Common Mistakes:

• Thinking sitemap controls blocking
• Assuming meta tags block robots.txt rules
• Ignoring file location importance

5. A website has many product pages, but some are outdated and low quality. How can crawl budget optimization be applied to improve SEO?

hard

A. Use robots.txt to block outdated pages and update sitemap with important product pages

B. Delete all product pages to reduce crawl budget usage

C. Increase website loading speed only

D. Add all pages to sitemap without blocking any

Solution

1. Step 1: Identify outdated pages handling

   Blocking outdated, low-quality pages via robots.txt prevents wasting crawl budget on them.

2. Step 2: Highlight important pages

   Updating sitemap to include important product pages guides search engines to crawl valuable content.

3. Final Answer:

   Use robots.txt to block outdated pages and update sitemap with important product pages -> Option A

4. Quick Check:

   Block bad pages + sitemap good pages = optimized crawl budget [OK]

Hint: Block bad pages, list good pages in sitemap [OK]

Common Mistakes:

• Deleting all pages instead of selective blocking
• Ignoring sitemap updates
• Thinking speed alone optimizes crawl budget
