SEO Tools & Calculators

Free tools to measure and improve your organic marketing performance — website traffic, page speed impact, NPS, and marketing health.

Measuring What Drives Organic Growth

SEO is often discussed in terms of keyword rankings and backlinks — but the metrics that translate to revenue are conversion rate, traffic quality, and page experience. This set of tools helps you quantify the business impact of technical and content SEO improvements, so you can prioritise the work that actually moves the needle.

Website Traffic: Estimating Your Organic Opportunity

Organic traffic is one of the most valuable and sustainable sources of visitors for any website. Unlike paid traffic, which stops the moment you stop spending, organic traffic compounds over time as you publish more content and earn more links. The Website Traffic Calculator helps you model what your organic traffic could look like as you improve your SEO — so you can set realistic targets and justify content investment decisions.

Why Page Speed Is Your Highest-ROI SEO Investment

Page speed is the only SEO factor that directly affects both your search rankings (via Core Web Vitals) and your conversion rate simultaneously. Google’s research shows a 1-second improvement in load time can increase conversions by 7%. For sites with thousands of monthly visitors, this compounds quickly into significant revenue — without increasing ad spend or content volume. Core Web Vitals — Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) — are now direct Google ranking signals. Use the Website Speed Impact Calculator to quantify your specific revenue opportunity from faster load times.

NPS and Marketing Health as Growth Indicators

Net Promoter Score measures customer satisfaction and loyalty — a leading indicator of organic growth through referrals and word-of-mouth. Businesses with NPS above 50 typically see 2–3× the organic referral traffic of those below 20. A high NPS means your existing customers are actively recommending you, which drives word-of-mouth traffic that Google cannot easily track or replicate with paid ads. Use the NPS Calculator to score your latest survey results instantly.

Marketing Health Check: Your Foundation Audit

Many businesses invest in SEO tactics before addressing gaps in their marketing foundation — and then wonder why results are slow. The Marketing Health Check is a 10-question quiz that scores your marketing foundation across tracking, messaging, channel mix, and conversion infrastructure. Identifying and fixing these foundational gaps often delivers more organic growth than any specific SEO tactic.

How to Prioritise Your SEO Work

  1. Fix technical issues first. Crawl errors, broken links, slow load times, and missing canonical tags undermine all other SEO work. Use the Website Speed Impact Calculator to quantify the revenue impact of speed improvements.
  2. Focus on high-intent keywords. Commercial and transactional keywords convert better than informational ones. Prioritise content that addresses specific problems your customers are actively searching to solve.
  3. Build content depth. Google rewards pages that comprehensively answer a topic. A single 2,000-word pillar page often outranks five 400-word pages on related subtopics.
  4. Earn links through useful content. Calculators, data-driven research, and original tools attract natural backlinks. Publishing tools like these is one of the most reliable organic link-building strategies.
  5. Measure what matters. Track organic sessions, keyword rankings, conversion rate from organic traffic, and revenue attributed to organic search — not just raw traffic numbers.
