3 conversion rate calculators to help you work out the opportunities from your Internet marketing

I've always believed that one of the best ways to convince your colleagues or boss to invest in digital media is to help them see the "size of the prize" and where your missing out - what is the gap between potential and current "how much money are your leaving on the table?".

Over the years I've created a lot of spreadsheet-based models to help with this, but this week I'm prompted to post on some alternatives since David Sealey who has recently written for us about conversion rate improvement let me know about a tool that his company is offering, so I'll start with that and then share a couple more with you.

1 Simple conversion rate calculator in Powerpoint

This calculator from David Sealey at Quba takes a conversion model right down to basics, so it's great as a starting point for small businesses, but remember that conversion rates for Ecommerce vary dramatically by new or repeat customers, by channel and of course by product category.

2. Excel conversion rate calculator

Going to a greater level of accuracy/complexity, I developed this conversion rate calculator to help companies see the potential improvements possible across all of Internet marketing including improvements to acquisition and reduction in returns. It also includes the costs of conversion rate optimisation projects.

This is one of several worksheets to help model performance in our optimisation toolkit other worksheets enable you to calculate conversion rates by channel which is important to a more accurate model since conversion rates by channel will vary dramatically,usually in the order paid search (non branded) > natural search > display ads depending on the level of familiarity,

3. Interactive  Ecommerce conversion spreadsheet

Finally, the most impressive/accurate conversion model is from Matthew Tod of Logan Tod which he uses to demonstrate improvements to clients or when training on Ecommerce sales optimisation. If you follow the link below you'll see that this fully interactive - no spreadsheets required!

Use Logan Tod conversion rate model.
