The Best KPI for Law Firm Digital Marketing

One of the many challenges of digital marketing is gauging whether your current strategy is working or not. Without using KPIs, or Key Performance Indicators, you will only be getting vague estimates and no clear picture if your firm’s goals are really being achieved.

Tracking your online presence and trajectory using KPIs will ensure that you see the full picture. It will enable you to evaluate your strategies more effectively and adjust them when needed.

Digital marketing thrives on the proper use of KPIs because almost everything can be measured and quantified.

If you ask marketers, or search online, you’re sure to end up with long lists of potential KPIs that can quickly become confusing. The perfect set of KPIs for your law firm is going to vary somewhat depending on how you do your marketing and how you run your firm, but there are a few common KPIs that will give you a very good picture of how well your marketing efforts are paying off no matter how you run things.

2. Client Acquisition Cost 

In digital marketing, there are potential customers and actual customers (or clients). Client acquisition cost shows you how much you spend to convert a potential customer into an actual customer.

3. Landing Page Conversion Rates

A is distinct from your main website and is designed around a focused objective. Landing pages, to be considered effective, must generate conversions regularly. It must clearly communicate the action you want your leads to follow when they land on your website.

To show your visitors the path you want them to take, it is ideal to provide limited options. This will guide them towards whatever your intended goal is, whether it be buying a product or subscribing to your newsletter. This way, tracking becomes simpler.

4. Average Time of Conversion

This KPI tracks how long it takes for leads to convert into actual paying clients. It may seem trivial, but tracking the time will show how effective or ineffective your sales process is.

To alleviate slow conversion, you can promote time-sensitive discount offers to expedite sales. You can also create a remarketing calendar to consistently remind your prospective customers of your service.

Tracking your average time of conversion will help answer the following questions:

5. Cost per Lead

Just as it’s important to understand how much a new client costs in marketing output, it’s also important to understand how much a lead costs you. You can calculate this by taking your total marketing spend and dividing it by the number of leads you’ve acquired. You can do this month over month and year over year to get a thorough understanding of how beneficial your marketing is. You can get even more granular with this data by leveraging a customer journey analytics tool like the one HubSpot has. This will tell you which channels the lead came in contact with and from there you can understand how much you needed to invest in your marketing in order to acquire this lead.

6. Return on Investment

Return on investment or ROI is the most classic digital marketing KPI. This KPI lets you know if your investment in marketing is truly worth it. A negative ROI showcases that your marketing is not working well enough to justify your spend. You can calculate ROI by subtracting the initial investment cost from your final value then dividing this new number by the cost of investment. And finally, multiplying that by 100.

7. Pages per Session/ Average Session Duration

In order to understand if your website is engaging users you must look at more data besides how many sessions your website gets. On top of that, you should also look at how many pages users view in a session and what the average session duration is. Anything more than 4 pages per session is great, but lower than 2 is concerning. A solid average session duration is between 2-4 minutes. You can get more granular with this KPI by looking at these data points for each of your channels to see how engaged users are on your website based on which channel brought them there.

8. Click Through Rate

CTR showcases how many users have viewed an ad, email, or web page, and have clicked on a link after viewing your content. Most platforms for email, advertising, or website tracking showcase the CTR.

9. Keywords in Top 10 SERP

It’s important to have an understanding of how the keywords you’ve targeted are doing from month to month. A good indication that your SEO strategy is working is if you’re seeing more keywords ranking in the top 10 on search engines.

10. Qualified Leads per Month

Sure, generating leads is important, but only if they are qualified. You can use your CRM software to categorize the different leads that come in and whether or not they are qualified.
