Analyze the time complexity of the following SEO content strategy process.

// For each new article published
for each article in website:
  research keywords
  write content
  optimize for SEO

Input Size (n)	Approx. Operations
10 articles	10 times the work of one article
100 articles	100 times the work of one article
1000 articles	1000 times the work of one article

Pattern observation: The effort and impact grow steadily as you add more content.
