The Importance of SEO ROI
Measuring the SEO performance and the return on investment of organic search lets you understand the efficiency of your campaigns. It also provides a benchmark for how your efforts translate into leads, sales, and revenue and lets you know what strategies to direct your time and budget next year. Despite the clear benefits, over a third of marketers responding to Marketing Week’s survey say their company rarely or never measures the ROI of its marketing spend.
SEO ROI Statistics by Industry
The ROI of SEO campaigns varies depending on the niche you’re in. The reason why some industries see better results is influenced not only by competition but also by factors like customer behavior, profit margins, and search trends. Please note that the following SEO ROI statistics take into account the period between 1-3 years:
- B2B SaaS businesses experience an average ROI of 702% from search engine optimization. (FirstPageSage).
- B2B companies generate twice as much revenue from organic search compared to any other channel. (BrightEdge).
- The ROI of SEO for businesses offering legal services is approximately 526%. (FirstPageSage).

PPC vs SEO ROI Statistics
When businesses want to increase sales, they usually take one of two routes — SEO or PPC. Sometimes, they do both to see better results. So, which one has a higher return on investment?
- 70% of marketers confirm that SEO generates more sales for them than PPC. (Databox)
- SEO delivers an 8x return compared to PPC’s 4x, according to poll data from NP Digital. (LinkedIn)

Databox survey respondents say that SEO works better than ads because it helps generate leads organically through high-quality content. Business owners who optimize their sites and create content that offers value to potential clients can consistently attract qualified leads through their websites over time.
The Conversion Rate of SEO Campaigns
FirstPageSage analyzed their internal data and found that the average conversion rate for SEO is 2.4%. As with other SEO performance indicators, this percentage also varies by the industry. For example, B2B SaaS companies have a rate of 2.1 percent, while for local businesses like HVAC this number is 3.3%. When it comes to legal services, this industry has the highest conversion rate of 7.5%.
Comparing SEO to Other Marketing Channels
A Search Engine Land poll found that 49% of respondents see organic search as the top ROI-driving digital channel. This shows that nearly half of marketers rely on SEO to generate more revenue compared to options like paid search, social media, or email marketing. Let’s take a look at the SEO ROI statistics behind this:

But when done right, a well-planned SEO strategy can bring in consistent traffic and flow of leads that turn into business growth.
