What are SEO services? They're paid work that changes a website, or advises on it, so Google can crawl, index and rank it. An agency, consultant or freelancer delivers them as audits, fixes, content and links.

If you're holding a proposal full of line items like "technical SEO", "content" and "reporting", you can't tell yet which ones are real work. Most buyers can't, because the names describe activities and say nothing about what you end up with.

This guide gives you a way to read each line. Some lines change your site. Others hand you a document you act on. A line that does neither is a checklist entry.

In this guide:

- The types of SEO services and what each one delivers
- A three-part test for whether a line item is a real service
- How to tell which of Google's stages is failing on your site, so you buy the right line first

## What are SEO services?

SEO services are paid work to improve a site's performance in Google Search, and site-changing work acts on one or two of three stages: crawling, indexing and serving.

SEO stands for search engine optimization. Google Search works in three stages, and not all pages make it through each one. Crawling is Googlebot fetching pages. Indexing is Google processing a page's content and metadata and storing it. Serving is choosing which indexed pages to show for a query.

Each stage can fail on its own. Googlebot doesn't crawl every page it discovers: some pages are disallowed by the site owner, and others sit behind a login. Indexing isn't guaranteed either, because not every page Google processes ends up in the index. And indexing depends on the page's content and its metadata, so thin or unclear pages stall there.

Link building touches a stage too. Google discovers new pages when it extracts a link from a known page, and through sitemaps, so links are one route into crawling.

Here's the split that matters for a buyer. Work that changes the site, such as technical fixes, page edits, content, links and migrations, acts on one or two of those stages. Supporting work (audit, keyword research, reporting, training) moves no stage. It produces a document or a measurement, and its value is the decision you make with it.

Google's own list of what providers sell contains both kinds. In its guide on [whether you need an SEO](https://developers.google.com/search/docs/fundamentals/do-i-need-seo), it names eight services, including content development, technical advice, keyword research, training and optimizing for generative AI. Keyword research and training sit on the same list as the site fixes, yet neither changes a single page.

Google also states that it never accepts money to include or rank sites. No service can buy you a place in the results. What you buy is work on the stages above, and the rest of this post is about checking that work.

If you want the mechanism behind the stages, Google documents them in [how Search works](https://developers.google.com/search/docs/fundamentals/how-search-works). Relevance at the serving stage is decided by hundreds of factors, with no published count, which is why no provider can promise a specific rank.

## Types of SEO services and what each delivers

SEO services come in three types of work (technical, on-page and off-page) plus supporting work, and every line item should hand you something you can check.

Those three types of SEO services are the usual way to sort a proposal. Stages and deliverables tell you more. Technical work changes how the site is built and served. On-page work changes the content and markup of individual pages. Off-page work changes what other sites say and link to about you. Supporting work sits outside all three because it leaves the site untouched.

So what do SEO services include? This table maps each line to the stage it acts on, what you receive and how you check it. Those are the SEO service deliverables worth asking for:

| Service line | Class and stage | What you receive | How you check it |
|---|---|---|---|
| SEO audit | Supporting, no stage | A written findings document with estimates of improvement and of the work involved | Every finding names a page or setting you can open, and every estimate names the work behind it |
| Technical SEO | Site-changing; crawling and indexing | Crawl export, redirect map, indexation report | Submitted URLs show as indexed in Search Console |
| Keyword research | Supporting, no stage | A keyword list mapped to pages you have or will publish | Each keyword has an owner page, and the list changes what gets written next |
| On-page SEO and content | Site-changing; indexing and serving | Edited pages and new pages, with titles, headings and copy | The pages are live as briefed and show as indexed |
| Link building | Site-changing; crawling and serving | New references to named pages on other sites | A log of which pages earned references, not a score |
| SEO migration | Site-changing; crawling and indexing | URL inventory and redirect map | Old URLs resolve to their new pages, and the new pages show as indexed |
| Reporting | Supporting, no stage | A recurring report tied to the lines you bought | You can name which work moved which number |
| AI search optimization | Site-changing; serving (content work) | Pages written or restructured for AI answers | The pages are live and you can see whether AI answers cite them |
| SEO training | Supporting, no stage | Sessions and written material for your team | Your team repeats the task unaided |

The stage cells are our own mapping from Google's stage documentation, since Google publishes no stage per service. Read the table as a rule: site-changing lines should leave a change you can open and verify, and supporting lines should leave something you can act on.

### Search engine optimization example: one page, one service line

Take a category page that sits in your sitemap but shows as not indexed in Search Console. The cause is a disallow rule that blocks Googlebot from crawling it.

The technical SEO line removes that rule, so the change is in the site's crawl rules and the stage it acts on is crawling. Indexing comes next and depends on the page's content and metadata. The acceptance check is that the URL now shows as indexed. If it doesn't, the line moves on to the content and metadata, and the indexation report says where it stopped.

### Supporting work: what you receive

Supporting work is where buyers get lost. Keyword research, reporting, training and audits change nothing on the site, so what you receive is a document or measurement. The check is the decision it lets you make. For example, a keyword list that changes nothing about what gets published or fixed was a spreadsheet, and you paid for a service.

That's also why an [SEO audit](https://missiongrowth.io/blog/how-to-do-seo-audit) belongs in the supporting column. It tells you what to fix and roughly what the fix involves. It doesn't fix anything. Ask for the audit's steps in the report so you can compare them with what you were sold.

[SEO reporting](https://missiongrowth.io/blog/seo-reporting) is the other line people overbuy. A report only counts as a deliverable when every figure ties to a line you paid for.

Content is the line with the most variance. A site-changing content line should name the pages, the topic each answers and how they get written, and [seo content writing](https://missiongrowth.io/blog/seo-content-writing) covers that craft in detail. Optimizing for generative AI is on Google's own list of provider services, so an [AI SEO services](https://missiongrowth.io/blog/ai-seo-services) line is legitimate. Treat it as content work at the serving stage, with the same check: live pages you can open.

### Scope labels and costs

Scope is a label that rides on a work type. Local, national, e-commerce and international say who the work is for. A fair quote names one work type and one scope label, for example "technical SEO for an e-commerce store". If a proposal says "local, national or e-commerce SEO" without a work type, it hasn't told you what you'll receive.

If a reader asks what a line costs, that belongs to [seo cost](https://missiongrowth.io/blog/seo-cost). This post stays on what each line is and delivers.

## How to tell a real SEO service from a checklist

A real SEO service names its class, the artifact you receive and the check that proves delivery, and a line item that names neither the change nor the artifact is a checklist entry.

"Improve technical health" is a checklist entry. It could mean anything, so nobody can say it wasn't done.

A scope statement fixes that. Here are two you can copy into a proposal review.

Technical SEO line (site-changing):

- **Class:** changes the site, acting on crawling and indexing.
- **Artifacts:** a crawl export, a redirect map and an indexation report for the sitemap URLs.
- **Acceptance check:** the URLs you submitted in the sitemap show as indexed in Search Console.

If the acceptance check fails, the stage is still failing, and you have a clear reason to ask for rework. Google notes that indexing depends on page content and metadata and that owners can disallow crawling, so those are the first places the report should look.

Reporting line (supporting):

- **Class:** supporting work, no stage moved.
- **Artifact:** a monthly report in which every figure ties to a service line you bought.
- **Acceptance check:** you can name which work moved which number.

A reporting line that ties every figure to purchased work can be audited. A dashboard of rankings with no link to the work can't, and you'd be paying for a mirror.

Run any line item through three questions. What class is it? What do I receive? How do I check it? If a line fails two of them, ask the provider to rewrite it before you sign.

## What access an SEO audit needs

An SEO audit needs read access to Search Console, and Google advises granting nothing more at the audit stage.

That matches what an audit is. Google says an audit should give you realistic estimates of improvement and of the work involved. So the artifact you receive from the audit line is a set of estimates plus the findings behind them. It isn't a set of changes made to your account.

So when a provider asks for audit access, check two things. They should ask for read access to Search Console, and they should promise estimates you can read before any work starts. For what an audit contains and how it runs, see [how to do seo audit](https://missiongrowth.io/blog/how-to-do-seo-audit). Contract and ownership checks sit in the agency comparison linked earlier.

## SEO services or DIY: which stage is failing

Buy SEO services when the failing stage needs skills you lack, and do it yourself when the work is small, local and within Google's starter guide.

Google says that if you run a small local business, you can probably do much of the work yourself.

So the question isn't "do I need SEO services?" but "which stage is failing?" Find the stage first, then ask for the matching line with its artifact.

Here's a rule you can apply today:

| What you see | Failing stage | Buy this line first | What you should receive |
|---|---|---|---|
| Pages exist but don't show as indexed | Crawling or indexing | Technical SEO | Crawl export, redirect map, indexation report |
| Pages are indexed but never appear for your topics | Serving | On-page SEO and content | Edited and new pages mapped to the queries you want |
| Pages are good, but a competitive market gives you no earned references | Crawling and serving | Link building | A log of pages that earned references |
| You're changing domain, URLs or platform | Crawling and indexing | SEO migration | URL inventory and redirect map |

If your site is small and local and the table points at on-page work, start with Google's own starter material and do it yourself. If the failing stage is technical or you're migrating, the skill gap is larger and the case for buying the line is stronger.

Mission Growth is an AI-led SEO and GEO growth service: AI catches the signal, our experts make the move, and you see the result. Whichever provider you pick, apply the same test: class, artifact and check.

Your next step is to open the report for your site in Search Console, find which stage is failing, and ask any provider to quote that one line as a scope statement with its artifact and acceptance check. A provider who can write that down is selling a service. One who can't is selling a checklist.

## FAQ

### What access should an SEO provider have during an audit?

Search Console read access only, with no write access at the audit stage, is Google's advice. An audit should return realistic estimates of improvement and of the work involved, so the provider doesn't need to change anything in your account to deliver it.

### What does a buyer receive from keyword research or reporting?

A document or a measurement, and the decision it feeds. Keyword research hands you a keyword list mapped to pages. Reporting hands you figures tied to the lines you bought. Neither changes your site, so the check is whether you can act on what you were given.

### What are the three types of SEO services?

Technical, on-page and off-page. Technical SEO changes how the site is built and served, on-page SEO changes page content and markup, and off-page SEO changes what other sites point to. Supporting work such as audits, keyword research, reporting and training sits alongside them, and scope labels say who the work is for.

### What do SEO services include?

Google lists eight services SEOs and agencies provide, including content development, technical advice, keyword research, SEO training and optimizing for generative AI. In our table those split into site-changing lines (technical, on-page and content, links, migration) and supporting lines (audit, keyword research, reporting, training).

### Do SEO services include AI search optimization?

Yes. Google lists optimizing for generative AI among the services providers sell. Treat it as content work at the serving stage and check it like any other site-changing line, by opening the live pages.

### How does SEO work, step by step?

Google Search runs in three steps. Step one, crawling: Googlebot fetches a page it discovered through a link or a sitemap. Step two, indexing: Google processes the page's content and metadata and stores it. Step three, serving: Google picks which indexed pages to show for a query. SEO work fixes whichever step a page fails.

### What is SEO? Definition and examples

SEO (search engine optimization) is the work of making your pages easy for Google to crawl, index and show in search results. Search engine optimization examples: removing a disallow rule so Googlebot can crawl a category page, rewriting a page's title and content so it answers the search it targets, and earning a link from another site so Google discovers the page.

### Can I do SEO myself?

Often, if your site is small. Google says a small local business can probably do much of the work itself. Buy a service when the failing stage needs skills you lack, such as a migration or a technical crawl problem.
