$1M Professional Liability (E&O) Insurance for SEO Agencies

In this guide

For SEO agencies whose client contract asks for $1M: your Professional Liability (E&O) policy pays up to $1M for a covered claim that your work cost a client money.

The short answer

  • A $1M requirement means your policy pays up to $1M per claim. Contracts often add an aggregate (the policy-year total), such as $1M/$1M or $1M/$2M.
  • Check whether the policy includes media liability (coverage for copyright, defamation and privacy claims over content you publish).
  • Morrow can review the contract requirement and your current policy, then help you find a $1M policy.

What does a $1M requirement mean for SEO agencies?

Professional Liability (E&O, short for Errors and Omissions) covers claims that your work caused a client a financial loss, such as through audits, site changes, content and links. A typical clause:

Illustrative contract wording

Vendor shall maintain Professional Liability insurance, including coverage for copyright and trademark infringement, defamation and invasion of privacy, with limits of not less than $1,000,000 per claim and $2,000,000 in the aggregate, covering all search engine optimization, content and website services under this Agreement.

Sample wording for illustration. Your contract's wording controls.

  • Per claim: the most the policy pays for any one claim. Here, $1M.
  • Aggregate: the most the policy pays for all claims in one policy year. Here, $2M. A $1M/$1M policy would not meet this sample clause. $1M/$2M would.
  • "Content and website services": the clause reaches blog posts you write and site changes you make. Check whether your policy covers both.
  • Claims-made: Professional Liability is almost always claims-made. The policy pays for claims first made against you and reported while it is active, usually for work done on or after the retroactive date (the earliest work date the policy covers). See claims-made vs occurrence.

Hypothetical examples: a site migration left old pages unredirected (not pointed to the new pages) and sales fell. A freelance writer copied another site's article.

Who asks SEO agencies for $1M?

$1M is a common number when a client asks. It often comes from:

  • E-commerce brands whose sales depend on organic search.
  • Multi-location businesses, such as franchises and clinics.
  • Software and B2B companies with vendor onboarding.
  • Larger agencies that white-label (resell under their own name) your SEO work.
  • Enterprise brands, hospitals, universities and public agencies. They may also ask for more than $1M on site migrations or long retainers (see $2M for SEO agencies).

How is $1M built?

At $1M, the limit is usually one primary policy (the policy that pays first). A $2M requirement may need a higher primary limit or excess (a layer above the primary). SEO agencies often need media liability, and some forms leave it out, so ask. If you also build websites or tools, a Technology E&O form may fit better (see Technology E&O vs Miscellaneous E&O).

Compare the contract to the policy. Check whether published content is covered, whether lost traffic claims are excluded, and whether your promise to pay the client's losses (an indemnity) is covered. A commercial umbrella (a policy that adds limit above other policies) almost never covers Professional Liability. Clients usually cannot be added as an additional insured (a party who gets coverage under your policy). Availability varies by carrier. A certificate of insurance (proof of your coverage and limits) alone does not make a client an additional insured.

Good to know

Defense costs can use up the limit. Many Professional Liability policies pay defense costs inside the limit. If a client sues over lost sales, lawyer fees come out of the same $1M as a settlement. Check the limit of liability section of the policy.

What will underwriters ask for?

An underwriter is the insurer's person who decides whether to offer coverage and on what terms. They usually ask about:

  • Your services and the revenue share of each, such as technical SEO, content, link building and site migrations.
  • Whether your contracts promise rankings or traffic, or tie fees to results.
  • How you build links, and whether freelancers or overseas vendors write or build links for you.
  • How you check content: plagiarism checks, AI draft review, image licenses and client sign-off.
  • Your access to client sites, and whether you back up and test changes on a practice copy (a staging site) first.
  • Client industries, revenue, prior claims or demand letters, and your current policy and retroactive date.

What affects the cost?

  • Services. Site migrations and hands-on development usually cost more than audits alone.
  • Contract terms. Ranking promises and pay-for-results deals can raise the price.
  • Client mix. Large e-commerce and regulated clients raise the price.
  • Claims history. Prior claims or demand letters can raise the price.
  • Policy terms. A higher aggregate usually costs more. A higher retention (the amount you pay on each claim before the policy pays, like a deductible) usually lowers the premium. See what drives the cost.

Frequently asked questions

Do I need $1M Professional Liability as an SEO agency?

Only if a client contract, a client's vendor onboarding or your own risk review calls for it. Read the insurance section of each contract before you sign.

Will the policy cover a client whose rankings dropped after a Google update?

Sometimes, depending on the wording. If a client says your error caused the drop, the policy may pay to defend you. Many policies exclude promised results, so a missed ranking goal is often not covered.

Do I also need Cyber insurance as an SEO agency?

Many SEO agencies also look at Cyber insurance. Agencies often hold admin logins (passwords that let you change a client's site). Professional Liability is about errors in your services. Cyber insurance covers data breaches and hacking.

Is $1M/$1M enough if my contract says $1M/$2M?

No, a $1M/$1M policy has a lower aggregate than a $1M/$2M requirement. Ask Morrow to request new $1M/$2M quotes, keeping your retroactive date and prior acts coverage (coverage for past work done before the new policy starts) where the market allows. Keep your current policy in force until the new one starts, and report anything that could become a claim to your current carrier before it ends.
