Short answer
Walk away from anyone who guarantees rankings, sells links, or will not explain exactly what they change. Ask for a written scope, monthly reports from your own Google Search Console, ownership of all content and accounts, and a contract you can exit with a month's notice.
Do you need an SEO agency at all?
Google's own page, Do you need an SEO?, says a small local business can probably do much of the work itself, starting with the free SEO starter guide. It also says a good time to hire help is when you are redesigning or launching a site, so it is built to be search-friendly from the start.
Before you compare agencies, check whether the problem is simpler. If your site is not appearing on Google at all, our guide to why a website is not showing on Google covers indexing issues that no monthly retainer will fix. For local businesses, a complete Google Business Profile often brings more calls than a new page.

Red flags that expose a bad SEO agency
Google's hiring advice is blunt about the warning signs. These are worth checking before any meeting.
A trustworthy SEO
- Explains every change and the reasoning behind it
- Asks what makes your business different and who your competitors are
- Gives realistic estimates and a measurement plan
- Cites official Google documentation for recommendations
Red flags
- Guarantees a number one ranking or page one in a fixed time
- Claims a special relationship with Google or priority submission
- Sells link packages, guest posts or directory submissions
- Sends unsolicited emails saying your site is not listed
- Is secretive about what they will change on your site
Google's spam policies define link spam to include exchanging money, goods or services for links, excessive link exchanges, automated link building and paid articles with links that pass ranking credit. Scaled content abuse (mass-produced pages made to manipulate rankings) and expired domain abuse are also listed. Google's hiring page adds that if an SEO creates deceptive content for you, your site can be removed from Google's index, and that you are responsible for what the people you hire do.
Questions to ask an SEO agency before you sign
Google suggests interviewing potential SEOs. These questions build on its list and add the commercial ones Singapore SMEs should ask.
- Can you show examples of previous work, and can I speak to a past client?
- Do you follow Google Search Essentials and its spam policies? How?
- What results do you expect, in what timeframe, and how will you measure them?
- What exactly will you change on my site each month? Will you tell me before you change it?
- Where will links come from? Do you pay for any of them?
- Who writes the content, who owns it, and is any of it AI-generated?
- What access do you need, and will you work from my accounts or yours?
- What is the minimum contract, notice period and exit process?
If they offer an audit, Google advises giving read-only access to Search Console at that stage, not write access. If they use a third-party tool's score, remember Google does not endorse third-party SEO tools and those tools do not see Google's ranking data.
Reporting, ownership and contracts
Good reporting comes from your own data. Google Search Console shows the queries you appear for, clicks, impressions and indexing errors. Ask for monthly reports that use it, alongside enquiries or sales from your analytics, not a tool's private visibility score.
Contract and ownership checklist
Be careful with arrangements where the agency publishes content on its own domains or network and links to you. If the contract ends and those pages are removed, the benefit goes with them, and the links may fall foul of Google's spam policies in the first place.
What a small SEO budget can realistically buy
Google's starter guide says changes can take anywhere from a few hours to several months to show, and suggests waiting a few weeks before judging the effect. A small business with a modest budget gets the most from fixing foundations first, then producing a small number of genuinely useful pages.
Our SEO cost guide for Singapore explains how one-off and monthly SEO are priced. AI search tools are changing where people find businesses too; our guide to visibility in ChatGPT and Google AI Overviews covers what still matters. Google's hiring page asks whether an agency's AI optimisation advice matches Google's official guidance.
Do it yourself or get help?
If your site is technically sound and you can write about your services, you can handle local SEO yourself with Search Console and Google Business Profile. Hire help for the technical foundation, a redesign or competitive searches where content and authority matter, and use the questions above when you do.
Our Speed & SEO Fix (S$390) is a fixed one-off package: speed clean-up, titles and headings, sitemap and Search Console set-up, with a before-and-after report. We do not sell monthly link building. If the site itself needs rebuilding, the Business Website (S$1,490) is built with on-page SEO and a sitemap from day one.
Frequently asked questions
No. Google states that no one can guarantee a number one ranking and advises being wary of SEOs who claim to guarantee rankings, claim a special relationship with Google, or advertise priority submission. Rankings depend on Google's systems, competitors and your content. A trustworthy agency gives realistic estimates and explains how it will measure progress.
Google's spam policies list buying or selling links for ranking purposes as link spam. That includes paying for links, exchanging goods or services for links, and paid articles or guest posts with links that pass ranking credit. Sites involved can lose rankings. Paid placements should use link attributes that tell Google not to pass ranking credit.
Google says some changes take effect in a few hours and others take several months, and suggests waiting a few weeks before judging whether a change helped. Technical fixes can show quickly once pages are recrawled. New content and reputation usually take months. Be wary of any timeline presented as a guarantee.
Add them as users to your own Search Console, Analytics and Google Business Profile rather than letting them create the accounts. Google advises read-only Search Console access during an audit. Website access should be a separate user account you can remove, and the agency should explain every change made to the site.
Be cautious. A long minimum term makes sense only if the scope, deliverables and reporting are clear and you can see the work each month. A short initial term followed by month-to-month billing, with a one-month notice period and a full handover, protects a small business if the work does not deliver.
