SEO fundamentals haven’t changed as much as the headlines suggest. Search engines still need to find your pages, understand what they’re about, and decide they’re the most useful answer for the person searching. AI Overviews, answer engines and constant algorithm updates change how results look. They don’t change those three jobs.
This guide covers the fundamentals in the order they matter, with the checks I’d run on any site before spending a cent on tools or link building. It’s based on Google’s own SEO Starter Guide.
1. Crawling: can search engines reach your pages?
If Google can’t crawl a page, nothing else matters. The basics:
- Verify your site in Google Search Console and Bing Webmaster Tools. Both are free.
- Submit an XML sitemap. SEO plugins like Yoast generate one automatically.
- Check that robots.txt isn’t blocking important sections. It happens more than you’d think after a redesign or a staging site goes live.
- Make sure important pages are linked from somewhere. A page with no internal links is hard to discover and signals it isn’t important.
2. Indexing: does Google choose to keep them?
Crawled isn’t the same as indexed. In Search Console, the Pages report shows which URLs are indexed and why others aren’t. Common reasons include duplicate content, thin pages, a noindex tag left on by mistake, or pages Google crawled and decided weren’t worth keeping.
That last category is a content problem, not a technical one. If a large share of your site sits in “Crawled, currently not indexed”, improve or merge those pages rather than resubmitting them.
3. Relevance: does each page clearly answer one query?
Every important page should target one main topic and the questions around it. That means:
- A title tag that says what the page is about, ideally with the main keyword near the start, in about 60 characters or fewer.
- A meta description that earns the click. Google often rewrites it, but a good one still helps.
- One H1 and logical H2s that follow the questions a reader would ask.
- The answer early. If someone searches “how long does a Schengen visa take”, the first paragraph should say.
- Descriptive URLs, such as /schengen-visa-processing-time/ rather than /page?id=4821.
Avoid two pages targeting the same query. They compete with each other, and often neither ranks well. Merging them is usually the fix.
4. Quality: is this the most useful result?
Most of the ranking decision happens at this stage, and it is where most sites fall short. Google’s guidance on creating helpful, reliable, people-first content asks whether content shows first-hand experience, real expertise and original information, rather than summarizing what’s already out there.
In practice, that means real examples, your own data or screenshots, clear opinions, and a named author with relevant experience. A page that reads like every other page on the topic has no reason to outrank them.
5. Page experience: is it fast and usable on a phone?
Most searches happen on mobile. Check your key pages with PageSpeed Insights and the Core Web Vitals report in Search Console. The usual fixes are compressing images, reducing heavy scripts and page-builder bloat, and using a good host with caching. Make sure pop-ups don’t cover the content on mobile, and that buttons are big enough to tap.
6. Authority: do other sites vouch for you?
Links from relevant, reputable sites still help pages rank. The white-hat ways to earn them are dull but effective: publish something worth citing (original data, a useful tool, a clear guide), get listed in genuine industry directories and local business listings, and build relationships with partners and publications in your field.
Don’t buy links or join link schemes. It breaks Google’s spam policies and the risk isn’t worth it for a real business.
7. Local and international signals
If you serve customers in a specific city, a complete Google Business Profile with accurate details and real reviews matters more than almost anything on this list. If you serve several countries, make each market’s page clearly relevant to it: local currency, local phone numbers, and hreflang tags if you have separate language or country versions.
A 30-minute SEO fundamentals check
- Search Console: are your key pages indexed? Any errors in the Pages report?
- Search your brand name: do your own pages come up first?
- Search your main service plus city or country: where do you appear, and what do the top results do better?
- Open your three most important pages on a phone. Are they fast and easy to read?
- Check titles and meta descriptions for those pages. Would you click them?
Fix what that check turns up before chasing anything advanced. Get the SEO fundamentals right and every later effort, from content to links, works harder.
