What's the average cost of enterprise SEO company services?
There is no average you can rely on. A price figure is only meaningful with a named measurement behind it that states its sample, date, and method, and enterprise engagements differ so much in scope that even a well-measured average would hide more than it shows. What you can do is test whether a quote reflects real enterprise scope: work that exists because of the size of the site, the number of teams involved, and the number of markets served. If a proposal cannot point to that work, the enterprise label is a price tier rather than a description.
What makes work “enterprise” scale
Size is the clearest marker, and Google gives a useful yardstick. Its guide to managing crawl budget is written “primarily” for “Large sites (1 million+ unique pages) with content that changes moderately often (once a week)” and “Medium or larger sites (10,000+ unique pages) with very rapidly changing content (daily).” Google adds: “The numbers given here are a rough estimate to help you classify your site. These are not exact thresholds.” For smaller sites the same guide is plain: “If your site doesn’t have a large number of pages that change rapidly, or if your pages seem to be crawled the same day that they are published, you don’t need to read this guide.” It continues: “For Google Search specifically, keeping your sitemap up to date and checking the Page Indexing report regularly is adequate.”
That gives you a practical check. If a proposal charges for crawl budget management on a site of a few hundred pages that are crawled promptly, it is selling more than Google’s own guidance says such a site needs.
What raises the cost at that scale
On a very large site, pages cannot be reviewed one by one. The work moves to templates, site sections, and rules that apply to thousands of pages at once, and a single change can affect a large part of the site. That ties SEO to the engineering team’s release schedule and testing process, and senior people spend time planning changes with developers rather than making them directly.
The number of people involved adds cost too. Changes to a large site may need sign-off from product, engineering, legal, brand, and regional teams, and each round of review takes time that a small engagement never pays for.
Serving several countries or languages multiplies the work. Each market needs its own keyword research, its own content, and the technical setup that tells search engines which version of a page is meant for which audience.
Content and links scale with the site as well. A large catalog or product range can need many category or use-case pages, and outreach for a well-known brand passes through brand and legal checks before anything is sent.
Reading an enterprise quote
Ask the company to break the price down by the scope behind it: which sections of the site, how many templates, how many markets, which teams it will work with, and what it will deliver each month. Ask how the work reaches your site. If every change goes through your engineering team, the proposal should say how many changes it assumes per release and who writes the specifications. Ask which parts are fixed and which depend on your teams’ capacity.
Comparing quotes
Put the quotes side by side by scope, not by headline figure. A lower quote that covers one market and leaves implementation to you can cost more in the end than a higher one that includes the engineering coordination your site needs. Where a line in one quote has no match in another, ask the second company whether it is included before you compare prices.
