Start With Keyword Research

Keyword research is the process of identifying the search terms your target audience uses when looking for your products, services, or content. Without it, you are guessing at what to write about.

Good keyword research identifies three things: what people are searching for, how often they search for it (search volume), and how difficult it is to rank for it (keyword difficulty). The sweet spot is high-intent, moderate-difficulty keywords where you can realistically compete.

Search Intent Is Everything

Every keyword has an underlying intent: informational (learning), navigational (finding a specific site), commercial (comparing options), or transactional (ready to buy). Matching your content to the right intent is the single most important on-page factor — more important than keyword density or word count.

Site Architecture: Structure That Search Engines Love

A well-structured site helps search engines crawl and index your content efficiently, and helps users navigate to what they need. A flat structure (where every page is reachable within 3 clicks from the homepage) is ideal for most sites.

Topic clusters — a cornerstone pillar page supported by linked cluster posts — are particularly effective for building topical authority. They signal to search engines that your site covers a subject in depth.

Content Quality: The Highest Leverage SEO Investment

High-quality content answers the searcher's question better than any competing page. It is comprehensive, accurate, well-structured, and written for humans first. The days of thin, keyword-stuffed content are long over.

What 'Quality' Actually Means

Quality is context-dependent. A buying guide needs depth and comparison tables. A how-to needs clear steps and visuals. A local service page needs relevant specifics about the location and service. In each case, ask: does this page satisfy the searcher better than the pages currently ranking?

On-Page Fundamentals Checklist

  • Title tag: include your primary keyword, keep under 60 characters
  • Meta description: compelling summary that earns clicks, 155 characters
  • H1: one per page, matches the search intent and primary keyword
  • H2/H3 structure: logical hierarchy that organises your content
  • Image alt text: descriptive, keyword-relevant where appropriate
  • Internal links: connect related content across your site
  • Page speed: target under 2.5s LCP on mobile

Frequently Asked Questions

Can I do keyword research without paid tools?

Yes. Google Search Console, Google Autocomplete, and People Also Ask are all free tools that reveal real search demand. Paid tools like Ahrefs or SEMrush give you volume and difficulty data, but you can build a solid keyword strategy without them.

How many keywords should I target per page?

One primary keyword (or topic) per page, supported by semantically related secondary keywords. Trying to rank a single page for dozens of unrelated keywords is ineffective. Focus each page on a single search intent.

How often should I publish new content?

Consistency matters more than frequency. A site that publishes two well-researched posts per month outperforms one that publishes daily low-quality content. Start with a cadence you can sustain, then scale up.
