Step 1: crawling
Search engines use programs called crawlers, such as Googlebot, to follow links from page to page. They find new pages through links and through sitemaps you submit.
If no link points to a page and it is not in a sitemap, a crawler may never find it.
Step 2: indexing
After crawling, the search engine analyses the page: its text, images, structure and meaning. If the page is judged worth keeping, it is stored in the index.
Not every crawled page is indexed. Thin, duplicate or blocked pages are often left out. Only indexed pages can appear in results.
Step 3: ranking
When someone searches, the engine picks from its index and orders the results. Google uses many signals. The main groups are:
- Relevance. Does the page match what the search means?
- Quality. Is the content helpful, accurate and written with real experience?
- Authority. Do trusted sites link to it?
- Usability. Is it fast and easy to use on a phone?
- Context. Where is the searcher, and what language did they use?
Search intent
The same topic can need different pages. "What is a root canal" wants an explanation. "Root canal cost Lahore" wants prices and a clinic. Google ranks the page type that fits the intent, so check what currently ranks before writing. See the keyword research guide.
Local results
For searches with local intent, Google shows a map with three businesses. That ranking uses different signals: distance, relevance and prominence, driven by your Google Business Profile and reviews. See the local SEO guide.
Where AI answers fit
Google's AI Overviews, ChatGPT, Gemini and Perplexity generate a written answer and cite sources. They still depend on crawled and indexed web pages to do it. Pages that rank well and state facts clearly are more likely to be cited. See how to rank in AI engines.
What this means for your site
- Make pages easy to crawl: technical SEO.
- Make each page clearly about one thing: on-page SEO.
- Earn trust from other sites: off-page SEO.
Frequently asked questions
How long does Google take to index a new page?
From a few hours to several weeks. Submitting the URL in Search Console and linking to it from existing pages speeds it up.
Can I pay Google to rank higher?
No. Payment only buys ads, which are labelled. Organic rankings cannot be bought from Google.
Is Google the only search engine that matters in Pakistan?
Google handles the great majority of searches here. Bing matters more than it used to because some AI tools draw on its index.
