Most buyers still start with a search box. Search Engine Optimisation decides whether they find you, a competitor, or nothing useful at all.

Search Engine Optimisation
What is Search Engine Optimisation?
SEO is the practice of structuring a website and its content so search engines can crawl, understand, and rank it for the queries your buyers actually type. It covers three broad areas: technical health (can search engines access and read your site), on-page content (does each page answer a real query clearly), and off-page authority (do other credible sites vouch for you).
None of these areas work in isolation. A technically perfect site with thin content will not rank, and a brilliant article buried behind a broken sitemap will never be found. SEO is the discipline of getting all three right at once, then maintaining them as your site grows.
Why SEO matters
Search remains one of the few channels where demand comes to you already formed. Someone searching for a solution to their problem is further along than someone scrolling a social feed. Ranking well for those searches means capturing intent at the exact moment it exists, without paying for every click.
- §Compounding traffic. A well-optimised page can keep earning visits for years, unlike a paid ad that stops the moment budget runs out.
- §Lower acquisition cost. Organic traffic does not carry a per-click price tag, so it improves margins as it scales.
- §Trust signal. Buyers still treat a strong organic ranking as a proxy for credibility, particularly in B2B research.
- §Foundation for AEO. Pages that rank well are more likely to be pulled into AI answer engines as sources, so SEO underpins Answer Engine Optimisation too.
The SEO process, step by step
1. Audit technical health
Check crawlability, indexation, site speed, mobile usability, and Core Web Vitals. Nothing else matters if search engines cannot access your pages.
2. Research keywords and intent
Identify the queries your buyers use, grouped into clusters by topic and by where the searcher sits in their buying journey.
3. Map keywords to pages
Decide which existing pages should target which clusters, and where new pages are needed to fill gaps.
4. Optimise on-page content
Write clear titles, headings, and body copy that answer the query directly, backed by internal links to related pages.
5. Fix internal linking
Make sure your most important pages are easy to reach from your homepage and from other relevant content, not buried three clicks deep.
6. Build authority
Earn links and mentions from credible, relevant sites. Quality and relevance matter far more than volume.
7. Monitor and iterate
Track rankings, traffic, and conversions monthly, and adjust the plan as search results and competitors change.
Common mistakes to avoid
×Chasing keyword volume instead of matching search intent. A high-volume term that does not fit your buyer wastes the effort.
×Publishing content with no internal links to it, leaving new pages orphaned and hard for search engines to find.
×Ignoring technical debt. Slow pages and broken redirects quietly cap how well even great content can rank.
×Treating SEO as a one-off project rather than an ongoing programme. Competitors publish, algorithms update, and rankings drift.
×Writing for search engines instead of people. Keyword-stuffed copy reads badly and converts worse, even if it briefly ranks.
How to measure SEO performance
Rankings alone are a vanity metric if they do not translate into visits and revenue. A useful measurement framework tracks each stage of the funnel:
- §Visibility. Rankings and SERP presence for your target keyword clusters.
- §Organic traffic. Sessions from search, segmented by landing page so you know which content is doing the work.
- §Engagement. Bounce rate and time on page, which flag whether the content actually answers the query.
- §Conversions. Signups, demos, or sales attributed to organic traffic, the metric that ties SEO to revenue.
- §Crawl and index health. Pages crawled versus pages indexed, and any errors surfaced in Search Console.
What the MarketJargon SEO agents do
The SEO Audit Agent crawls your site, checks indexability, speed, and metadata, and returns a prioritised list of fixes with a 30/60/90-day roadmap. It is the starting point for most SEO programmes because it tells you exactly where the leaks are before you spend on content or links.
Once the technical foundation is sound, the Keyword Research Agent finds and clusters the terms your buyers search for, mapped to funnel stage and suggested page format. The Content Brief Agent then turns each cluster into a structured brief a writer can follow, so content gets built against evidence rather than guesswork.
Many teams also pair these with the AEO Agent and the AI Search Citation Agent so the same pages that rank in search are also structured to earn AI citations.
SEO terms worth knowing
A handful of terms come up constantly in SEO work. It is worth knowing them before you read an audit report or brief an agency:
- §SERP, the page search engines return for a query, links, ads, and increasingly AI overviews.
- §Keyword Cluster, a group of related search terms best served by a single page or set of pages.
- §AEO, the related discipline of optimising for AI answer engines rather than search rankings.
Frequently asked questions
How long does SEO take to work?+
Most sites need three to six months of consistent work before rankings move meaningfully, and longer in competitive categories. Technical fixes can help within weeks; content and authority gains take longer to compound.
Is SEO still worth it now that AI answers exist?+
Yes. Search engines still send the majority of discovery traffic for most businesses, and AI answer engines often draw their citations from pages that already rank well. Strong SEO underpins both.
Do I need to hire an agency, or can one agent handle it?+
The SEO Audit Agent covers the technical and on-page diagnosis end to end. Larger sites with complex information architecture may still want a specialist for implementation, but the audit and roadmap rarely need one.
What's the single highest-impact thing to fix first?+
It depends on the audit, but indexability problems, pages that search engines cannot crawl or are told not to index, usually come first. There is no point improving content that Google cannot see.
How is SEO different from AEO?+
SEO gets your pages discovered, crawled, and ranked. AEO shapes those same pages so AI answer engines can extract and cite them. The two work together rather than replacing one another.
