SEO, search engine optimisation, is the sum of all measures that help your website be found, understood and ranked higher by Google. It is not a single lever but the interplay of technical quality, content and the trust other websites place in you. Once you understand the basic logic, it is clear why results take time and where to start.
How does Google find your site in the first place?
Think of Google as a very diligent librarian who walks through the web, reads every book it finds and shelves it in a catalogue. A software crawler (a "bot") does exactly that: it moves from page to page via links, loads your pages and adds them to the index, the huge digital shelf that search results are drawn from.
Two points matter:
- Reachability: if the crawler cannot find or load your site (for example because of broken links, very slow loading or blocked areas), Google simply does not know you exist.
- Comprehensibility: Google must grasp your content, what you offer, who it is for, which question the page answers. Clear text and clean structure help it do that.
How does Google decide who ranks at the top?
For "plumber in Dresden", Google probably has hundreds of matching pages to choose from. It has to work out which one helps the searcher best. Hundreds of factors play a part, which fall into three main groups:
| Area | What it means | Examples |
|---|---|---|
| Technical SEO | The site is easy for crawlers to read and fast | clean URLs, loading speed, mobile, HTTPS |
| On-page SEO | The content matches the search intent | clear titles, structured text, relevant terms |
| Off-page SEO | Other sites refer to yours | backlinks, mentions, reviews |
Why does SEO take months instead of days?
Google has to visit your site repeatedly, observe your content and judge whether the people who click on it are satisfied. That trust builds up only gradually and can be lost again if the site is unreachable for a while or content goes missing.
Two things make this realistic:
- The strength of the competition: against established sites with many backlinks and years of content, you need time to appear equally strong.
- Consistency beats intensity: steady, good work over months is more effective than one big push that then ends.
As a rule of thumb: within three to six months you should see measurable changes in visibility and enquiries, if you stop earlier, you usually quit just before it works.
What should SMEs do first?
You do not need to tackle everything at once. In most small and mid-sized businesses, this order has the biggest effect:
- Define your target terms: what do your customers actually search for? (e.g. "web design Dresden", "bookkeeper for startups")
- Check your Google Business Profile: name, address, category, opening hours, photos and reviews kept up to date
- Sharpen your most important pages: the three to five pages your customers really need, written clearly and specifically, no filler
- Check the technical basics: loading speed, mobile view, HTTPS, the classics that are quick to fix
- Plan your content: work on one topic each month that your customers actually search for
Conclusion
SEO is not a trick but a system of technology, content and trust and it takes patience. Understanding the basic logic helps you avoid the most common mistakes: giving up too early, changing everything at once, or staring at rankings instead of real customer enquiries.
