Everything you need to know before hiring a CRO agency

Updated:

Pageviews, impressions, clicks and opens are worth nothing if you are unable to convince prospects and buyers to take some action. Regardless of how you get people to your site - whether via organic search, email marketing, or paid acquisition - it is getting increasingly more expensive (and competitive) to get traffic online hence the importance of getting the most value out of every visitor.

We often see companies spending huge amounts of time and money on paid advertising - on keyword research, going back and forth with agencies on creative and constant tweaking of ad targeting - all whilst pointing to an unoptimised and poorly converting landing page.

Conversion rate optimisation (CRO) is the scientific process by which you get more from your existing marketing spend and campaign activity. With conversion rate optimisation and a CRO agency you can:

A small increase in conversion rates can result in big increases in revenue, particularly for B2B companies that have larger deal sizes. For a website that receives 10,000 visitors a month and converts 1% of those visitors to MQLs, that’s 100 MQLs per month. A relatively modest increase in conversion rate from 1% to 3% would result in an additional 200 leads. For a mid-market business with an average contract value of £20,000, with a 5% MQL to SQL conversion rate, that modest conversion rate improvement equates to an additional £200,000 of sales pipeline a month, or £2.4M a year.

It’s much easier to double your business by doubling your conversion rate than by doubling your traffic.

What are some conversion rate optimisation (CRO) examples?

Here are some public examples of conversion rate optimisation successes.

Conversion.com worked with Voices.com, a leading marketplace for voice-over talent, to increase website conversion rates by 400% over the course of 11 conversion rate optimisation experiments. Experiments included adding social proof in the form of happy companies, segmenting website visitors, creating demonstration videos and email marketing.

Conversion rate experts worked with Moz.com, the provider of SEO and inbound marketing software. The first split test CRE ran for Moz generated a 52% improvement in sales, and within the first 4 months of work annual revenues increased by $1 million. Experiments included a more long-form, content-rich homepage, added a chart to show all features, added existing client logos and testimonials and testing new calls-to-action.
