About Reuben

I’m a hands-on growth marketing consultant offering my expertise to B2B startups to improve lead generation. I help across three critical areas: marketing analytics, conversion rate optimisation and performance marketing/paid media.

I have worked at multiple early stage startups across B2C and B2B, from health-tech to ed-tech. Over 7 years of testing, learning and iterating brings accomplishments that makes the challenges worth it. Some highlights in that time include:

  • Scaling 6-figure PPC campaigns and organic conversions for a product that unlocked safe travel during the pandemic
  • Launching a lead gen strategy and building pipeline for an innovative, painless employee health screening benefit
  • Boosting inbound B2B opportunities for a L&D platform five-fold, which has now been acquired
  • Restructuring Google Ads accounts to surpass previous record of SQLs generated
  • ...and much more
Typical projects with me include:

  • Google Analytics & Google Tag Manager audit/setup and repair (plus Google Ads or paid media conversion tracking) - typically a ~3 day engagement
  • B2B website audit & roadmap for A/B tests and experiments to improve conversion rate and lead generation - followed by executing this - typically ~1.5 days per week over ~3/mo
  • Launching or optimising Google Ads, LinkedIn Ads or other paid media channels like Gartner - this would include auditing current activity and ads strategy, then improving the accounts to hit agreed KPIs - typically ~1-2 days per week

    SEO Consultant

    August 2023 - September 2023 (1 month)
    In 2023 I collaborated with Wandering Wheels, a UK-based campervan conversion company, to create a starter SEO strategy. Like most SEO work, the aim was to improve visibility and generate organic traffic for their site. At the time, most of their traffic came from social media and referral sites. Steady, but not enough to drive business value. With no prior SEO experience in-house and a low domain authority, the challenge was to deliver quick wins and quality traffic while setting a scalable framework for continued growth.

    TLDR; The results
    • Over 2000 sessions generated within approximately 6 weeks of deployment
    • Average engagement time of 1m 30s+
    • Engaged session rate of ~75%
    • Installation of GA4 and connection to GSC to analyse results and monitor search hygiene
