What Is SEO
Leafline is a small online shop that sells indoor plants and publishes care guides. Asha, the owner, wrote an excellent snake plant watering guide from years of her own records, yet it never appears when people search "how often to water a snake plant". Writing a good page is half the job. The other half is making sure search engines can find it, understand it and trust it.
The rule
Be findable, be understandable, be trustworthy — then be chosen.
Search engine optimisation (SEO) is the work of earning unpaid visibility in search results for the searches your pages genuinely answer. Before a search engine shows a page, it needs a yes to three questions:
- Can I find it? The engine's crawler must reach the page, through links or a sitemap, and load it. A page linked from nowhere does not exist as far as search is concerned.
- Do I understand it? The page must make its topic plain: a clear title, headings that match the question, text that answers it directly.
- Do I trust it? Among dozens of pages on the same topic, the engine prefers ones that show real knowledge and that other reputable sites refer to.
These three questions map to the three everyday areas of SEO work:
| Question | Area of work | Leafline example |
|---|---|---|
| Can I find it? | Technical SEO | The guide is linked from the Guides page and listed in the sitemap |
| Do I understand it? | Content (on-page) SEO | The title names the question: "How Often to Water a Snake Plant" |
| Do I trust it? | Authority | A gardening magazine links to the guide |
SEO is not a trick layered on top of a site. It is making a genuinely good page legible to a machine that is trying to serve the searcher.
The shortcut
When a page is not showing up, walk the three questions in order and stop at the first "no". Trust cannot rescue a page the engine cannot find.
Can the engine find it?
The guide is only linked from a newsletter email: no page on the site links to it and it is missing from the sitemap. First "no" found.
The common trap is jumping straight to the third question: chasing links for a page that search engines cannot even reach.
Drills
Answer fast — trust the rule.
Which visits does SEO aim to earn?
Leafline's new page is not linked from anywhere and is not in the sitemap. Which question fails first?
Which change mainly helps a search engine understand a page?
Asha is offered links to a guide that currently shows an error when it loads. What does the shortcut say?
Remember
- SEO earns unpaid visibility for the searches your pages genuinely answer.
- Walk find → understand → trust in order, and fix the first "no".
- The trap: chasing links or keywords for a page the engine cannot even reach.
