How SEO works
Google describes SEO as helping search engines understand your content, and helping people decide whether to visit your site from a search (Google SEO Starter Guide). A search engine crawls pages, stores them in an index, then ranks the pages that best answer each search.
Most SEO work falls into three parts:
- Technical SEO: making pages fast, crawlable and indexable.
- On-page SEO: writing titles, headings and content that match what people search.
- Off-page SEO: earning backlinks and mentions from other sites.
Links matter more than most beginners expect. Google says the vast majority of new pages it finds every day are found through links from pages it has already crawled (the same guide).
SEO in Pakistan
A clinic in Lahore, a clothing brand selling on Daraz and a freelancer on Upwork all compete for searches. A local business mostly needs local SEO so it shows on Google Maps. A freelancer usually sells SEO audits, content and link work to clients abroad.
SEO results build over time, because a search engine has to find, crawl and re-assess your pages after every change. That is why SEO is a skill you practise on real sites, not a trick you apply once.
