  • From what little I remember from my Finance Degree, your ROI mathematics look solid. The biggest challenge (especially for a new business) is figuring out what the true lifetime value of a customer is. There are a couple of snags that people can run into:

    1) The business is too new to know what the true lifetime value is. If this is the case, always round your expectations way down so your plan takes into account those pesky worst case scenarios.

    2) The Lifetime value of a customer varies depending on the marketing channel the customer came from. Be wary of applying a Lifetime Value that was obtained from other channels. Each method of customer acquisition can have a very different lifetime value. For example, someone who was referred to you by a friend will probably have a different lifetime value than a customer obtained from a promotional coupon. It is best to get some information about the customers obtained through the online channel to get a good estimate before making big assumptions.

    3) The numbers don’t line up. Some companies think they have nailed their numbers but are still losing money. Make sure to reevaluate how much your customers are actually spending with you on a periodic basis to make sure you are using accurate info.

    Once you have an accurate lifetime value estimate, Dan’s formula above will lead you down the road to calculating an ROI that will have the executives drooling and your client list full!

  • Also, be carefull when using the acronym LTV, as this means more than one thing in the financial world. In this example it means LifeTime Value, but it is also common to use LTV to mean Loan To Value when speaking about money.

    Make sure eveyone you are communicating with is on the same page!

    • Excellent point Jeff. It’s easy to get into a groove with your own acronyms. Generally I try to define those before getting into any kind of calculation. As a side note any Lifetime Value Calculation is extremely difficult to define.

      In my experience it has always been an estimation which is agreed upon by all business units (sales, marketing, operations, etc.)

  • What about branded searches? Do you include them in your SEO analysis? They are mostly driven by other marketing.

    Also, what periods do you look at for comparison? You dont start with zero visitors. Obviously there are cyclical trends, but also as your site ages it gains in authority (which will give more organic traffic but has nothing to do with your seo efforts).

    I am really struggeling with this, is there an SEO (software) system that can approach a reliable ROI meassure? Something like omniture wont do because a. it doesnt have seo cost and b. cant distinguish between what you’ve paid for and what not.

    • Hi Bart,

      When putting together my SEO ROI I always break out branded search into a separate calculation, my reasoning behind this is that any branded search is a result of our overall branding efforts not simply any SEO program. Additionally ranking for your own brand name does not generally require any additional effort or resources (that is debatable however with any ROI calculation we have create a definition) – I am focusing on the ROI of your search team and resources for programs.

      Since developing an ROI for SEO is generally a baseline operation you need to set reasonable targets for a 12 month period, after that initial 12 month period you can then begin to integrate your SEO ROI with the other ROI calculations your organization will perform.

      As a site ages it will not by default gain authority – there are many old sites which do not gain authority and do not have rankings. I would argue that gaining in authority in large part due to a strong search program (this includes advising design teams, campaigns and ongoing online promotion). So I don’t think your assumption is 100% accurate 🙂

      As for tools to measure ROI on Search and SEO programs Google Web Analytics and Omniture can be setup to manage this type of calculation on a daily basis, both through funnels, goals and targets.

      Hope that helps!
