Understanding Time Complexity
When planning a guest posting strategy, it is important to understand how the effort and results grow as you increase the number of posts or sites involved.
We want to know how the work and impact scale when you add more guest posts.
Scenario Under Consideration
Analyze the time complexity of the following guest posting process.
for each website in target_websites:
find contact info
pitch guest post idea
if accepted:
write and submit post
wait for publication
track published posts
This code represents the steps taken for each website when executing a guest posting strategy.
Identify Repeating Operations
Look at what repeats as you add more websites.
- Primary operation: Looping through each target website to perform pitching and posting.
- How many times: Once for every website you want to guest post on.
How Execution Grows With Input
As you increase the number of websites, the total work grows in a straight line.
| Input Size (n) | Approx. Operations |
|---|---|
| 10 | 10 sets of pitching and posting steps |
| 100 | 100 sets of pitching and posting steps |
| 1000 | 1000 sets of pitching and posting steps |
Pattern observation: The effort grows directly with the number of websites you target.
Final Time Complexity
Time Complexity: O(n)
This means the total work increases in direct proportion to how many websites you include in your guest posting plan.
Common Mistake
[X] Wrong: "Adding more websites won't increase my work much because I can reuse the same pitch everywhere."
[OK] Correct: Even if the pitch is similar, you still need to find contacts, customize messages, write posts, and follow up for each site, so the work grows with each new website.
