Novidea: Top of Search for "Insurance Software" UK + US in 3 Months
Novidea had serious indexability issues keeping its insurtech SaaS platform out of Google's index. We led the site migration to fix the technical foundation — crawl architecture, canonicalisation, render path, hreflang for dual-market — then layered topical content depth and link signal alignment around the primary commercial keyword.

Overview
What is On-Page (Onpage) SEO?
On-page SEO—also known as onpage SEO—covers all optimisations made directly on your website pages: title tags, meta descriptions, heading structure, keyword placement, internal linking, and content quality. It's the foundation of any effective on-page SEO service.
It's the most controllable aspect of SEO. Unlike link building or algorithm changes, on-page optimisation is entirely within your control and can deliver quick wins. That's why our experts prioritise it for every client.
Most businesses have on-page issues they don't know about: duplicate titles, missing meta descriptions, thin content, poor heading structure, and keyword cannibalisation. An seo agency skilled in on-page analysis can uncover these problems quickly.
We audit every page, fix what's broken, and optimise what's underperforming—always with revenue impact as the priority. Our on-page SEO services are built around achieving organic growth through precision, not guesswork.
Optimised title tags alone can increase click-through rates by 20-40%.
Visionary is a world-leading SEO agency trusted by brands across the UK and beyond. Our senior specialists combine deep technical expertise with commercial strategy to deliver measurable organic growth.
DIY vs Agency
Can You Do On-Page SEO Yourself?
Some on-page SEO basics can be handled in-house if you have the time and access to basic tools. Writing clear, descriptive meta titles (50–60 characters), crafting meta descriptions that summarise page content, adding alt text to images for accessibility and SEO, using header tags (H1, H2, H3) to structure content logically, and ensuring internal links point to relevant pages—these fundamentals are manageable with basic WordPress knowledge.
Where it gets complicated is the work that separates adequate on-page SEO from the kind that drives serious organic growth:
- Keyword cannibalisation analysis — ensuring multiple pages aren't competing for the same keywords and diluting ranking potential
- Internal linking architecture — strategically linking pages to distribute authority, guide users, and establish topical relationships search engines understand
- Content gap identification — discovering which related questions your content should answer to improve topical coverage and rank for more keywords
- Schema markup implementation — adding structured data so search engines understand your content type (product reviews, FAQs, recipes, events)
- Core Web Vitals optimisation — technical page speed, interactivity, and visual stability that Google ranks by
- User experience signals — analysing scroll depth, click patterns, and engagement to identify pages users find unhelpful
The reality: most in-house SEO efforts cover about 20% of actual on-page opportunities. The other 80%—competitive analysis, advanced keyword mapping, technical implementation, ongoing testing—requires specialist tools (SEMrush, Ahrefs, Screaming Frog) and years of experience from dedicated seo specialists to execute effectively.
At Visionary, we start with a comprehensive on-page audit that identifies exactly what needs fixing on your site. We show you a priority list: what's critical, what's high-impact, and what's nice-to-have. You then decide what to handle in-house with our guidance and what to outsource to our experts. Many clients find that outsourcing the technical and strategic work while managing content in-house creates the best balance of control and results.

What an Element-by-Element On-Page Audit Surfaces
The element-by-element comparison below is what we actually find at engagement start versus what we set every element to.
| Dimension | Element | Typical state we find | What we set it to |
|---|---|---|---|
| Title tag | 'Site name | Page name' — generic | '[Primary keyword] [year] | [Modifier] | [Brand]' | |
| Meta description | Auto-generated or duplicated | 130–160 chars, click-baiting, includes primary + secondary intent | |
| H1 | Eyebrow text or duplicate of title | Substantive headline, semantically rich | |
| H2 / H3 hierarchy | Skipping levels, multiple H1s | Clean hierarchy, semantic chunking | |
| First-100-words | Generic intro paragraph | Direct answer to query intent (AI Overview optimisation) | |
| Image alt text | Empty or 'image' | Descriptive, keyword-relevant | |
| Internal links from page | <2 contextual links | 4–6 contextual, anchor-text-varied | |
| Internal links to page | Often orphaned | 3+ inbound from relevant cluster | |
| Schema | Missing or generic | Page-type-appropriate, validated | |
| Author byline | Missing or 'admin' | Named author, LinkedIn link, Person schema | |
| Last-reviewed date | Absent | Visible date + dateModified schema | |
| Source citations | Generic claims | Linked to authoritative sources |
EEAT signals
EEAT On-Page Signals — Beyond Title + Meta Basics
Most on-page audits stop at title / meta / schema. EEAT-evaluated queries (YMYL, financial, health, education) need more. Below are the EEAT-specific on-page signals we add. Skipping any one of these is the difference between content that ranks for EEAT-evaluated queries and content that gets quietly demoted.
Visible author byline + photo + LinkedIn link
Every commercial article — named, photographed, linked.
Last-reviewed date visible
Paired with dateModified in schema, surfaced on the page itself.
Source citations on factual claims
Outbound links to authoritative sources on every statistic.
Reviewed-by attribution
For technical / YMYL content, 'Reviewed by [Person]' with credentials.
Author Person schema with knowsAbout array
