SEO Basics, Without the Jargon

SEO felt like alphabet soup when I started

When I first sat down to learn SEO, I drowned in acronyms. SERP, DA, PA, CTR, UX, Core Web Vitals. Every blog post seemed to assume I already knew the other ten.

Honestly, most of the advice out there is overwhelming on purpose. People sell courses, audits, and tools, so the message is always “you need 200 things tracked and a weekly checklist.”

It’s noise.

SEO at the core is simple. Make your content easy for search engines to understand, and worth reading for the people searching. Done.

Let me walk through it the way I wish someone had explained it to me.

What SEO is, in one sentence

Search engines (mostly Google) want to surface useful pages. SEO is helping them see why yours is one.

It’s not tricking the algorithm. The tricks stop working. What sticks is clarity, quality, and a site people enjoy reading.

The three buckets I think in

1. Technical SEO — the foundation

If Google’s crawler hits a broken site, nothing else matters. The basics:

The site loads fast (Core Web Vitals are a real ranking signal)
It works on mobile (Google indexes the mobile version first)
URLs are clean and readable
A sitemap exists and is submitted to Search Console
Internal links make sense

If you’re on a modern static framework like Astro, most of this is handled out of the box. Still worth knowing what’s under the hood.

2. On-page SEO — the content

What most people picture when they hear “SEO.” Optimizing the page itself:

Descriptive H1 and H2 headings
Meta descriptions written for the page, not stuffed with keywords
Keywords used the way a human would say them, not jammed in
Internal links to related posts
Alt text on every image

The whole trick is writing for humans first. If a real person finds the page useful, you’re 90% of the way there.

3. Off-page SEO — the authority

Other sites linking to yours. Backlinks.

You don’t control this directly. The honest path is to write things people want to link to. Slow, but it compounds.

What doesn’t matter as much as people say

Keyword density. Stop counting.
Meta keywords tag. Google ignored it years ago.
Submitting your URL to search engines. If anything links to you, Google finds you.
Perfect scores in Lighthouse or Ahrefs. Useful as a checkup, not a goal.
Republishing old posts every month with a new date. Google sees through it.

A starter checklist

If you’re new and want one page to focus on:

Write something genuinely useful. Answer a real question.
H1 includes the main topic, in plain language
Meta description matches the page (155 characters or so)
Page loads in under 2.5 seconds on mobile
URL is readable: /seo-basics/ beats /?p=123
Internal links to two or three related posts
Alt text on images
Publish on a steady cadence, even if it’s slow

Do those eight things well and you’re ahead of most sites I look at.

The thing nobody wants to hear

Useful content ranks. Useless content doesn’t.

I know it sounds obvious. It’s still the part most people skip while chasing tactics.

Write something worth reading. Make it easy to scan. Make it findable. The rest is polish on top.

Where to go next

If you want to go deeper:

Core Web Vitals (LCP, INP, CLS) and how to fix each one
Search intent — informational vs transactional vs navigational
Crawling and indexing inside Google Search Console
Your own analytics, to see which posts pull weight

Don’t try to learn it all at once. Pick one rough edge on your site and fix it. Then the next one.

SEO is a long game. The sites I see win are the ones putting up something worth reading, week after week, for years.
