What to Look for in a Search Engine Optimization Company
A search engine optimization company should cover five baseline services: technical SEO, on-page optimization, local and Google Maps SEO, content creation and link building. Search engine optimization means helping search engines understand a site's content and helping people find that site, according to Google Search Central. Supporting that work means helping Google's automated crawlers find a site's pages and add them to its index.
A full-service company also covers two newer criteria: AI search optimization (AEO) and CRM integration. A CRM is the system a business uses to track leads and customer contacts.
Many business owners cannot tell a full-service agency apart from a freelancer who only handles one tactic, such as link building or on-page fixes. Older evaluation checklists do not mention AI search optimization or CRM and automation integration. That leaves out two criteria that now matter when a business picks a company to hire.
The Core Services a Full-Service SEO Company Should Offer
A full-service search engine optimization company should offer six core services. These are technical SEO, on-page optimization, local and Google Maps SEO, content creation, keyword research and link building. The SEO services page lists this range in detail. Each service covers a different part of how a site gets found and read. A company that handles only one service is not covering the full job.
Technical SEO covers the work that helps Google's crawlers find and read a site. Google uses crawlers that explore the web constantly, looking for pages to add to its index.
Local and Google Maps SEO is a separate skill from general SEO. Google ranks local search results by relevance, distance and prominence, according to Google Business Profile Help. There is no way to pay for a better local ranking on Google. The Google Maps local SEO service page covers how this work is done. Ask whether a prospective company tests for these specific signals, not just general keyword rankings.
This baseline connects to the site itself. A full-service company's work includes building custom websites, ecommerce stores and custom software. The same company offers SEO, AI search optimization and Google Maps and local SEO. Ask whether these pieces come from one team or get split across multiple vendors.
Why AI Search Optimization (AEO) Now Belongs on Every SEO Company's Checklist
Older checklists for choosing a search engine optimization company stop at traditional Google rankings. They do not ask whether the company also prepares a business for the AI platforms many searchers now use to find answers.
In Pew Research Center's analysis of searches from March 2025, about one in five Google searches produced an AI summary. Searchers who saw an AI summary clicked a traditional search result in 8% of visits. Those who did not see one clicked a traditional result in 15% of visits, according to Pew Research Center. That is what Pew measured for the searches in its study. It is not a result every business should expect.
AI search optimization (AEO) is a full-service SEO company's work. It helps AI platforms such as ChatGPT, Gemini and Grok find and use a business's information. This work can sit alongside traditional SEO and Google Maps and local SEO, as part of the same service scope. This makes AI search optimization one of two testable criteria this checklist adds that older agency-evaluation checklists skip.
See the AI search optimization services page for what this work covers.
Full-Service Agency vs. Single-Tactic Freelancer
A full-service agency and a single-tactic freelancer differ in scope, not effort. The agency's work spans technical fixes, content, local search, link building and AI search optimization. It also covers the paid ads and automation that turn site traffic into leads. A freelancer who sells one service, such as link building alone, works within that single area only.
Ask any prospective company for a written scope of work before you sign a contract. Check whether it lists technical SEO, on-page work, local and Google Maps SEO, content, link building, AI search optimization and CRM or automation work. A quote covering only one or two of these areas signals a single-tactic provider, not a full-service agency.
| Service area | Full-service agency | Single-tactic freelancer |
|---|---|---|
| Technical SEO (site speed, crawlability, structured data) | Included | Not included |
| On-page optimization | Included | Not included |
| Local and Google Maps SEO | Included | Not included |
| Content creation and keyword research | Included | May be the one service offered |
| Link building | Included | May be the one service offered |
| AI search optimization (AEO) | Included | Not included |
| Paid advertising (Google Ads, Meta ads) | Included | Not included |
| CRM and automation integration | Included | Not included |
This matches the full-service side of the comparison above. It includes SEO, AI search optimization (AEO) and Google Maps and local SEO. It also includes paid ad campaigns on Google Ads and Meta ads (Facebook and Instagram). And it includes social posts, articles and email campaigns, plus brand strategy and design.

Why Search Work Should Connect to Your CRM and Automation
Search traffic does not grow a business on its own. A visitor only becomes valuable once that visit turns into a lead the business can track and follow up with. Ask a prospective search engine optimization company whether its search work connects to how your business captures and manages leads. Find out if it stops at rankings and traffic instead.
One sign of this connection is a workspace that combines CRM, SEO and automation tools. A full-service provider may offer a workspace that combines a CRM, search optimization and a website or online store. That workspace can also include AI agents, automation and a built-in AI assistant. A lead from a search visit can move straight into that system instead of passing between separate tools.
Automation can also include an AI receptionist, website chat and appointment setting. These tools are designed to answer and schedule leads that search traffic brings in, so a lead does not go unanswered. A service covering AI receptionists, website chat and appointment setting is one place to check for this kind of follow-up.
Checking for this CRM and automation connection is one of two testable criteria this evaluation adds. Other top-ranking pages on this topic omit both this criterion and AI search optimization.
When Hiring an SEO Company Makes More Sense Than Building the Skill In-House
Building search optimization in-house can work when one team member keeps up with several specialties at once. Technical SEO, content, link building and AI search optimization each move on their own schedule. Keeping all of them current is a different task than mastering just one.
Before committing to an in-house approach, check whether your team has someone dedicated to each of these specialties. If not, the work may land on one generalist with other duties. A single generalist can struggle to keep every specialty current at the same time.
Hiring a full-service company closes that gap without adding a separate specialist for each area. One contract gives you access to the full range of skills covered in the checklist above, through a single point of contact.
The decision comes down to capacity rather than cost. Ask whether your team can keep every specialty current over time. If not, the work may be better handled by a company already staffed for all of it.
SEO Company Evaluation Checklist
A full-service search engine optimization company should offer seven core services. These include technical SEO, on-page optimization, and local and Google Maps SEO. They also include content creation, keyword research, link building, AI search optimization and CRM or automation integration. Ask a prospective company each of these yes-or-no questions before you compare proposals.
- Technical SEO: Does the company check your site's speed, crawlability and structured data (schema markup) so search engines can read the content?
- On-page optimization: Does the company optimize each page's title, headings and body content for the topic that page should rank for?
- Local and Google Maps SEO: Does the company manage your Google Business Profile and local search listings?
- Content creation and keyword research: Does the company research the keywords your customers search and build content around them?
- Link building: Does the company build links from other reputable websites back to your site?
- AI search optimization (AEO): Does the company optimize your business's information so AI platforms such as ChatGPT, Gemini and Grok can find and surface it?
- CRM and automation integration: Does the company connect search results to your CRM and automation tools, such as an AI receptionist, website chat or appointment setting?
If a company cannot answer yes to most of these, it likely covers one tactic. A full-service search engine optimization company should handle the full range above.
Questions to Ask Before You Sign a Contract
Before you sign, ask the company for business references. Call its past clients and ask whether the company gave useful service, was easy to work with, and got good results, as Google's hiring tips for an SEO recommend. A company that cannot name a past client is a warning sign.
Ask how the company talks about results. No one can guarantee a number one ranking on Google, and claims of a special relationship with Google are a warning sign. Treat promises like these as a reason to look elsewhere.
If the company offers to run an SEO audit, check what access it wants. It will likely ask for Search Console, Google's free tool for tracking site performance. Give it only read-only access at this stage, not write access. You can widen access later once you trust the relationship.
Know where to turn if something goes wrong. In the United States, you can file a complaint about deceptive or unfair SEO practices with the Federal Trade Commission. Keep this option in mind even after you sign a contract.
FAQ: Common Questions About Hiring a Search Engine Optimization Company
Can you pay for search engine optimization?
Yes, a business can pay a company to perform search engine optimization work. But no one can guarantee a #1 ranking on Google, and claims of a special relationship with Google are a warning sign. No business can request or pay for a better local search ranking either.
Is search engine optimization digital marketing?
Yes. Search engine optimization is the practice of helping search engines understand a website's content and helping users find that site. A full-service company offers that search work alongside paid advertising on Google Ads and Meta ads, as part of one digital marketing plan.
