Topic 1

Importance of search engines

ProcessHow search works
  1. 1Crawling

    Bots (Googlebot) discover pages by following links and sitemaps

  2. 2Indexing

    Pages are analysed and stored in the index

  3. 3Ranking

    Algorithms order results by relevance and quality

  4. 4Serving

    Results page with organic listings, ads, snippets, maps

  • Ranking factors: relevance to the query and intent, content quality and helpfulness, E-E-A-T (experience, expertise, authoritativeness, trustworthiness), backlinks, page experience (Core Web Vitals, mobile-friendliness, HTTPS), freshness, user location and history.
  • Major Google updates: Panda (2011, thin content), Penguin (2012, spammy links), Hummingbird (2013, semantic search), RankBrain (2015, machine learning), BERT (2019, language understanding), helpful content and core updates (2022 onward); AI Overviews now summarise answers for many queries.

Topic 2

Indexing and crawling

  • Crawl budget: the number of pages a search engine crawls on a site in a period — matters for large sites.
  • Controls: robots.txt (which paths bots may crawl), meta robots tags (noindex, nofollow), canonical tags (preferred version of duplicate pages), XML sitemaps (list of important URLs), Google Search Console (index coverage, URL inspection).
  • Common problems: blocked resources, duplicate content, broken links (404), redirect chains, orphan pages, slow servers.

Topic 3

The role of keywords in SEO

ComparisonKeyword types
Description
Example

Short-tail (head)

One or two words; high volume, high competition

"MBA college"

Long-tail

Specific phrases; lower volume, higher conversion

"MBA college in Ludhiana with placements"

Informational intent

Seeking knowledge

"What is digital marketing"

Navigational intent

Looking for a site

"SBS Ludhiana admission"

Transactional intent

Ready to act

"Apply for M.Sc IT 2026"

  • Keywords guide titles, headings, URLs, content and links so that search engines match pages to queries; stuffing keywords is penalised — write for users first.
