What is SEO and how is it done? A practical guide for 2026

SEO is the whole of the technical, editorial and authority work that gets a site showing up in search engines for relevant queries without paying for the placement. It differs from advertising in two ways: you don't pay per click, and the result comes from the quality of the site itself.

Below is what actually gets done on a site.

How many parts does SEO have?

None of the three substitutes for another. A site that's technically flawless but weak on content won't rank; a site with excellent content that can't be crawled won't be seen.

What does a technical SEO audit look at?

The audit runs off a checklist. These are the findings that come up most often:

Indexing. Which pages Google has, and why the missing ones are missing. The "Pages" report in Google Search Console is the starting point.

Duplicate titles and descriptions. Pages carrying the same title compete with each other in search results. On our own old site, five separate pages carried exactly the same title; this is one of the most expensive and most easily fixed faults there is.

Missing meta description. The description isn't a direct ranking signal, but it affects the click-through rate in the results. If you don't write one, Google picks a fragment from the page at random.

Heading hierarchy. One H1 per page, with a sensible run of H2s and H3s beneath it. Two H1s, or none at all, leaves it unclear what the page is about.

URL structure and canonicals. If the same content can be reached from several addresses — parameterised URLs, filters, the www and non-www versions — you have to state which one is authoritative.

Redirect chains and 404s. Consecutive redirects both cost speed and eat crawl budget.

Core Web Vitals. The page experience measures:

Verify the measurement with the field data in Search Console rather than a lab test; sites with a high lab score and poor real-user data are common.

Sitemap and robots.txt. Only pages you want indexed, and that return content, belong in the sitemap. Our old site's sitemap carried eight addresses that came from the theme template and returned no content at all. Addresses like that waste crawl budget.

Structured data (JSON-LD). Organization, LocalBusiness, Service, FAQPage, BreadcrumbList and Article are the most used. A common mistake is combining conflicting types in a single node.

How is content SEO planned?

A keyword list on its own isn't a plan. The plan starts by identifying the intent behind each query.

If the intent is matched wrongly, the page won't convert even when it ranks: a page explaining a definition to someone looking for a price sends that visitor straight back.

One page per subject

Producing several pages about the same subject splits the signal for it. Our old site had more than fifteen pages duplicated by swapping the district name; those pages competed with each other and gave the visitor nothing new. On the new site they were all merged into a single service page and the old addresses were 301'd.

Layout within the page

• Say what question the page answers, in a clear sentence in the first paragraph
• Write section headings as questions
• Give comparisons in real table markup
• Build definitions so they can be quoted in a single sentence
• Point the way to related pages with internal links

What does authority work mean?

Authority is other trustworthy sources referring to your site. Trying to build it with bought links may appear to work in the short term, but it runs against Google's spam policies and carries the risk of a penalty.

The sustainable routes are slower but they last: correct entries in trade association and chamber of commerce directories, appearing on trade fair and event pages, producing genuinely useful content and getting it shared, natural references on customer and supplier sites.

What does local SEO need?

In local search the first condition is consistency: the company name, address and phone number (NAP) must be written identically on the site, in the Google Business Profile and in directories. Three addresses written differently give a worse result than one.

On top of that come the right business category, real service descriptions, current opening hours, LocalBusiness structured data and customer reviews. Asking for reviews is legitimate; buying them is not.

What should you do to show up in AI search?

Overblown promises are common in this area, so let's separate out what's known. Google Search has stated plainly that it does not use the llms.txt file. A study published in May 2026 also showed that adding JSON-LD schema to pages already appearing in AI Overviews did not measurably increase the number of citations.

So the weight goes on the content: sections headed with questions, definitions quotable in one sentence, dated figures, comparison tables and real list and table markup. The technical side — llms.txt, structured data, server-side rendering — still gets done because it costs little, but it isn't presented as a magic answer.

How is the result measured?

The monthly report should carry this data:

• Search Console: impressions, clicks, click-through rate and average position, broken down by query and page
• Indexing: the number of indexed pages and the error records
• Core Web Vitals: the trend in field data
• GA4: organic sessions and conversions (form, phone, WhatsApp)
• The work done and the plan for next month

The position of a single word in a rank-tracking tool means nothing on its own; what to watch is the trend in total impressions and conversions.

How long does SEO take to work?

The effect of technical fixes usually shows up in indexing and impression data within a few weeks. Content and authority work take longer; depending on the competition, the age of the site and its current state, it's measured in months.

Offers promising first place within weeks aren't realistic. Offers that guarantee rankings are either built on words nobody searches for, or they use risky methods.

In short

SEO is a three-legged, ongoing job: a technical foundation, content that answers the search intent, and authority that accumulates over time. There's no shortcut, but it is measurable; every piece of work done has its counterpart in the Search Console data.
