How to compare SEO agency quotes beyond price
Compare SEO agency quotes not by price but by putting the scope of work, deliverable ownership, measurement criteria, change-history sharing, link terms and delivery deadline into the same table. Match the item names to the task names in Google Search Central's documentation.
When you get quotes from three vendors, one calls a task a "site diagnosis" while another calls the same task an "SEO audit." Searching for SEO agency or SEO consulting only turns up recommendation posts that list vendor names, so there is nothing to base a consistent comparison of the items on.
1. SEO vendor tasks and how they are named on quotes
The basic work of an SEO vendor is site review, technical advice, content development and keyword research. PION also checks bot access, indexing and sitemaps against the same standards during the site audit stage. Google Search Central's vendor-selection document, Do you need an SEO? (updated June 11, 2026), lists eight "useful services" a vendor can provide.
| Task in Google's document | Common name on quotes |
|---|---|
| Review of site content or structure | Site diagnosis, SEO audit |
| Technical advice on hosting, redirects, JavaScript | Technical SEO, on-page optimization |
| Content development | Content production, blog management |
| Keyword research | Keyword analysis |
| Online business development campaign management | Link building, promotion |
| SEO training | Training, written guidance |
| Providing expertise about the relevant markets and regions | Overseas SEO consulting, global SEO agency |
| Optimization for generative AI | AEO, GEO |
SEO consulting covers review, advice, and training, while the brand handles the edits and publishing. An SEO managed service means the vendor also executes content development and campaign management. Many companies call themselves consultants yet also do the managed-service work, so distinguish them by which rows appear on the quote. A quote labeled "specialized SEO firm" or "SEO service" is likewise a combination of the rows in this table.
2. Which Search Console figures should you write down before the meeting?
Before the meeting, jot down the number of indexed pages, the number of non-indexed pages, and the top three reasons for non-indexing. When PION audits a brand's site, we first pull up the Search Console page indexing report and compare those numbers against the diagnostic findings in the proposal.
- In Search Console's left menu, go to Indexing > Pages and write down the two numbers above the chart.
- From the "Why pages aren't indexed" table, copy the top three reasons in order of page count.
- Next to it, write the actual page count: the number of CMS posts plus the number of static pages.
- When the proposal arrives, compare it with these notes item by item and mark what the vendor has newly found.
The Page Indexing report help doc explains: "If the total number of URLs in this report is much lower than the number of pages on your site, then Google is not finding the pages on your site." If the actual page count you wrote in step 3 diverges from the total URL count in the report, the proposal should explain why. Actions for each reason are in the status-by-status table in Registered your site with Google but still not showing up? What to check.
In the meeting, ask all three candidates the question list from the vendor-selection document in the same order. For Search Console permissions, follow the same document's advice, "Grant only read access to Search Console", and start with the restricted user role from the Managing users, owners, and permissions help doc ("has view-only access to most data").
3. Quote items to compare besides price
Use one table to compare each quote's scope, deliverable ownership, measurement criteria, change-history sharing, link terms, and delivery deadlines.
| Comparison item | What to look for in the quote | If it is blank |
|---|---|---|
| Scope of work | Which of the eight tasks in the section 1 table are included, and their units | Out-of-scope work gets billed as an extra charge |
| Deliverable ownership | Who owns the published posts and edited pages after the contract ends | You have no grounds to reclaim the published posts |
| Measurement criteria | Which search queries are measured, with which tool, and at what weekly interval | You can't reproduce the rank report in Search Console |
| Change-history sharing | Whether all applied changes are shared, and whether the reasons for recommendations are explained | You get only results and don't know the cause |
| Link terms | Whether link quantity, placement sites, and compensation are stated | The risk in section 4 lands on the brand's site |
| Delivery deadline | Which outcomes are delivered by when, and how they are measured | There's no deadline against which to judge whether the work was delivered |
The vendor-selection document's questions "What results can you deliver, and over roughly what time frame do you expect them? And how can you measure the results?" and "Can you share all the changes you apply to the site and explain in detail your recommendations and the reasons for them?" correspond to the measurement-criteria and change-history rows. If the quote does not answer them, ask these exact questions in the meeting. Compare ranking figures using Search Console's average position. Google has stated that third-party tools "cannot access Google's internal ranking data."
4. Why to reject ranking guarantees
Google has stated that "no one can guarantee a #1 ranking in Google Search results," and if the method used to keep such a guarantee violates the spam policies, the brand's site bears the responsibility. Google Search Essentials (updated December 18, 2025) explains that "it never costs anything to appear in Google Search results, in any case."
The Spam policies for Google web search (updated September 2, 2026) classify "buying or selling links for ranking purposes" as link spam and "operating multiple websites with slightly different URLs and homepages" as doorway abuse, and state that violating sites "may rank lower or not appear at all in search results."
The vendor-selection document warns that "your site could be completely removed from Google's index," while making clear that "ultimately, you yourself are responsible for the behavior of the vendors you use." If a quote states a link quantity as a number, ask about the placement sites and the compensation; if the answer is undisclosed, exclude that row.
5. Do you need separate Google and Naver SEO agencies?
For technical checks, both search engines require the same items, so a single vendor suffices; you just need to check whether the quote includes Naver-only tasks, such as Search Advisor registration and RSS submission in Webmaster Tools. The ten items listed in Naver Search Advisor's The Purpose of Search Engine Optimization guide include robots.txt allowance, sitemap submission, removing noindex, and standard HTML links. They overlap with Google Search Essentials' requirements and recommendations. Naver states that "site registration is supported only at the host level," and its search robot is named Yeti, so in robots.txt you check the Googlebot group and the Yeti group separately.
Many of the vendors that come up in searches for Google SEO vendor or Google SEO agency also work as Naver SEO vendors. If a quote from a Google SEO agency or Google SEO consultancy includes rows for Search Advisor registration, Webmaster Tools RSS submission and channel-info markup, one vendor handles both; if not, contract the Naver work separately.
6. Can you hand AI search visibility to an SEO agency too?
The SEO tasks in the section 1 table can cover Google AI Overviews. Whether a brand appears in ChatGPT or Gemini answers is not captured in Search Console, so it has to be measured separately. The vendor-selection document includes, among its tool-evaluation items, "If there is advice about optimizing for AI environments (also called 'AEO' or 'GEO' services), does that advice align with Google Search's official guidance on optimizing for generative AI features?" and AI features and your website (updated December 31, 2025) states that for appearing in AI Overviews "there are no additional requirements." The items to compare in a measurement contract are in GEO agency recommendations: Why AI answers change and how to choose.
When you also hand over AI answer visibility, what PION handles and what the brand keeps are set out in the contract formats in the GEO managed-service overview. Of the self-checks in section 2, bot access and indexing status are asked in the same order in the AI answer visibility basics check.
Frequently asked questions
Which items should I check when choosing an SEO vendor?
Ask each candidate the interview questions provided by Google Search Central in the same order, and compare the scope of work, deliverable ownership, measurement criteria, change-history sharing and link terms in their quotes. If you write down the number of indexed pages, the number of non-indexed pages and the top 3 reasons for non-indexing from the Search Console page indexing report before the meeting, you can check during the meeting what the vendor's audit has newly found. PION pulls up the same report first during the site audit stage.
How does SEO consulting differ from an SEO managed service?
Consulting covers site review, technical advice, keyword research and training, with the brand handling edits and publishing; with a managed service, the vendor also executes content development and campaign management. Many vendors offer both consulting and managed services, so tell them apart by whether the quote includes implementation items. If you have someone in-house to write posts and edit the site, consulting is enough.
Should I sign with an SEO agency that guarantees rankings?
No, you should not. Google Search Central has stated that "no one can guarantee a #1 ranking in Google Search results." Buying and selling links or creating multiple similar sites to keep such a guarantee violates the spam policies, and the spam policy document advises that such sites may rank lower or be dropped from search results. The vendor-selection document makes clear that responsibility for the outcome lies with the site owner.
Do I need to contract a Google SEO vendor and a Naver SEO vendor separately?
For technical checks, a single vendor is enough. Google and Naver make the same demands on robots.txt, sitemaps, noindex and standard HTML links. The Naver-only tasks are Search Advisor registration, the RSS submission menu in Webmaster Tools and channel-info markup, and whether Naver's search robot Yeti is allowed in robots.txt is checked separately from Googlebot. If these items are on the quote, one vendor handles both; if not, contract the Naver work separately or do it yourself.
How much Search Console access should I give an SEO vendor?
In the diagnostic stage, add them as a restricted user. Google's vendor-selection document advises to "grant only read access to Search Console," and the Search Console help describes a restricted user as one who "has view-only access to most data." After signing, if you want the vendor to submit sitemaps and request indexing, add them as a full user, while the brand retains owner permissions.
