Website SEO statistics (service businesses and informational sites)
SEO statistics that matter most for service businesses, local businesses, blogs, and general informational sites. Many overlap with the general section above; these are the ones worth highlighting for non-SaaS, non-e-commerce sites.
Lead generation and ROI
| Stat | Number | Source |
|---|---|---|
| Marketers saying SEO has best ROI of any marketing channel | 49% | Digital Silk |

| Pages on the web with zero backlinks | 66.5% (and ~90.88% of them get zero Google traffic) | Backlinko |
Why most sites underperform
For service sites, blogs, and informational sites, the most common SEO problems are different from SaaS or e-commerce. The patterns we see most often:
- Title tags and meta descriptions not written for click-through, leading to low organic CTR even at decent rankings
- Content that targets keywords with no business intent, generating traffic that never converts
- Internal linking that doesn't pass authority to the pages you want to rank
- Local SEO basics missing or misconfigured (Google Business Profile, NAP consistency, local citations)
- Backlink profile too thin to compete in the niche
