The short answer
An SEO company does five kinds of work, usually at the same time:
- Technical work so search engines can crawl and index your site
- On-page work so each page matches what people search for
- Content that answers the questions buyers ask
- Authority building so other sites link to and mention yours
- Measurement so you know what the work produced
A good company treats these as one job. If you are offered only one of them, ask what happens to the rest.
What happens in the first month
The first month is mostly diagnosis and repair.
- Audit. The site is crawled and checked for anything that blocks indexing, slows pages or confuses Google.
- Tracking. Google Search Console and Google Analytics 4 are set up or corrected, with calls, forms and WhatsApp clicks counted as conversions.
- Keyword map. Each important page is assigned the searches it should rank for, so pages stop competing with each other.
- Fixes. The most damaging technical problems are fixed first.
You should receive the audit and the keyword map in writing. If you do not, ask for them.
What happens every month after that
| Work | What it looks like in practice |
|---|---|
| On-page optimisation | Titles, headings, copy and internal links improved page by page |
| Content | New service pages, guides or category text, plus refreshing pages that slipped |
| Link building | Outreach, digital PR, listings and partnerships that earn links |
| Technical upkeep | New errors caught as the site changes |
| Reporting | Rankings, traffic and enquiries, with an explanation |

What an SEO company should not do
- Guarantee rankings. Nobody outside Google controls them.
- Buy links in bulk or use private blog networks. These can lead to a penalty.
- Hold your accounts. Your Search Console, Analytics and Business Profile should be in your name.
- Report only rankings. Rankings that bring no enquiries are not a result.
- Hide the work. You should be able to see every page changed and every link earned.
How to tell if it is working
Expect a lag. In the first two to three months you should see technical issues closed, pages indexed and impressions rising in Search Console. Clicks and enquiries usually follow from month four onward, depending on competition.

Frequently asked questions
Is an SEO company the same as a digital marketing agency?
No. A digital marketing agency usually covers ads, social media and design as well. An SEO company focuses on organic search. Some agencies do SEO well; many treat it as an add-on.
Does an SEO company change my website?
Yes, with your approval. Most changes are to page text, titles, structure and code. Design changes are rare and agreed first.
Can I do SEO myself?
You can do the basics with time and patience. Our SEO checklist is a good start. Competitive markets usually need more hours and skills than an owner can spare.
