Brand promotion: this article introduces Guangsuan's Google SEO service. It is a vendor-introduction piece, not an independent review or a commissioned evaluation.
Two analysts on the same team run the same keyword in two different tools and come back with two different numbers. One says the demand is there; the other says the term is weak. The meeting that follows tends to go one of two ways: someone averages the two figures, or the budget decision stalls until next quarter. Neither is a decision.
This article covers the step in between: a short cross-check that tells you whether the two numbers are even describing the same thing, and, if they are, whether the remaining gap is small enough to act on. It then sets out what a Google SEO engagement actually covers, using Guangsuan's published Google SEO service as the reference point, since that is the vendor this article introduces. The cross-check itself applies to any tool and any provider.
The short answer
Google's own volume data lives inside Google Ads Keyword Planner, it is reported in ranges for accounts without ad spend, and every third-party volume figure is a model rather than a count. So the first question is not which number is right, but whether the two runs were configured the same way and which of four different measurements you actually need. If the settings differ, no judgment about the market is possible yet: schedule a matched re-run first. If they match and a gap remains, treat the result as a range and move to a go, test or hold decision instead of an average.
The practical order is: check that the two runs are comparable, add your own first-party data, write the decision down, and only then decide what to buy. Google Keyword Planner first for volume ranges and paid competition, Google Search Console for the queries your own site already receives, Google Trends for direction over time, and one paid tool only when you need estimated volume at scale, difficulty scores or competitor gaps.
Step 1: check whether the two runs are comparable
Before discussing trustworthiness, confirm the two runs describe the same thing. Write down these settings for both, and file the date each figure was pulled:
- Country or location - which market's searches are counted.
- Language - whether local-language and English queries are pooled together.
- Network - whether the figure covers Google Search alone or includes search partners.
- Month range - the historical window the average is taken over.
- Close variants - whether near-plurals and rewordings were grouped into one line.
The variants point deserves care. Keyword Planner's own column definition describes the figure as the average number of times people searched for a keyword and its close variants for the month range, location and network you selected. Two phrasings you consider distinct may therefore sit on one line in one tool and on two lines in another. The second tool will show two smaller numbers rather than one larger one, and neither figure is wrong; they are counting different groups.
Step 2: separate the four measurements people call search volume
Even with matched settings, two sources can disagree honestly because they answer different questions.
| Question | What it measures | Where it comes from |
|---|---|---|
| How many searches per month? | Estimated demand, usually expressed as a range | Keyword Planner; third-party keyword tools |
| Is interest rising or falling? | Relative interest on a 0-100 scale, not a count | Google Trends |
| How competitive is the paid auction? | Ad competition, competition index and bid ranges | Keyword Planner; the Google Ads API |
| How hard is it to rank organically? | A vendor's model of how strong the current top results are | Keyword-difficulty scores inside paid tools |
Treating one column as all four is where budgets drift. A high cost-per-click tells you advertisers value the term; it does not tell you that you can rank for it. A difficulty score is a vendor's model rather than a Google metric, and scores from two different vendors are not comparable with each other, so pick one tool and use it for relative comparisons only.
Step 3: add your own first-party data
Search Console is not a research tool for brand-new terms, but it is the source of your own real query data: the queries you already appear for, with impressions, clicks and average position. That makes it the place to start a keyword list you can defend, because those queries have already proved relevant to your site. Be clear about what it covers: it shows your own visibility, not total market demand, so a query your site has never appeared for will simply be absent from the report.
Trends is the counterpart for direction rather than size. It shows relative interest for a chosen geography and period, which is useful for seasonality and for comparing two terms, but it does not return search volume and its numbers should not be read as counts. Use it to decide whether a topic is growing, and a volume source to decide how big it is.
Step 4: write the decision down
One page per market decision, one row per keyword. The fields that do the work:
- Keyword, spelled out exactly, including any regional variant.
- Target market - country and language recorded separately.
- Each source with its settings, so the two rows can be compared line by line.
- The figure each source returned, quoted as returned.
- Known setting mismatch - the first thing to fix.
- First-party evidence from Search Console.
- Evidence gap, plus the named person who owns filling it.
- Decision - go, test or hold - and a review date.
Go commits a writer and a URL, so it needs the strongest evidence of the three. Test means a bounded build: one page, one market, a defined measurement window, used when demand looks plausible but the evidence is thin. Hold means not with this evidence, which is a decision rather than a dead end. It is reasonable to stop comparing once the mismatch is explained, once the disagreement no longer changes the decision, or once the gap is an unexplained order of magnitude.
What a Google SEO engagement covers, once the numbers agree
A keyword decision sits upstream of the work itself. Once targets are set, the practical question becomes which parts of the chain you will do and which parts you will hand over. Guangsuan describes its Google SEO service as three groups of work that support one another: technical optimisation, on-page content, and external link building.
- Technical optimisation: code optimisation, URL structure, internal linking, sitemap, robots file, 404 handling, SSL certificate and mobile adaptation - the stated goal being that Google can crawl the site smoothly and users can open pages quickly.
- On-page optimisation: original and vertically relevant content, differentiating titles rather than repeated keywords, keywords placed rather than stuffed, and a consistent publishing rhythm.
- Link building: external references built through the provider's own resource sites, managed as a commercial service with delivery quantity, indexing status and link attributes checked against the project plan.
Two statements belong beside that description because they are the vendor's own. Guangsuan states that its link products and layered build model are its own execution method, not a Google certification or an officially confirmed weighting step. And it maintains its own independent-site link resources for client projects rather than reselling placements made by someone else.
If you want to see how the three layers, the packages and the delivery terms are published, Guangsuan's Google SEO service page sets them out. For the tool-by-tool comparison behind Step 2 above, the companion article on what tools show Google keyword search volume, trends and competition walks through the sources one by one.
What to prepare before you ask any provider
The first conversation is more useful when a few inputs exist on your side: the live site address; the main products or services and what you do not offer; the target country or language, stated separately; how you currently acquire customers; a rough budget range; and your Search Console export if you have one. The last two matter most. A budget range tells a provider whether the full scope is realistic, and the Search Console export is the only baseline that will let anyone judge progress later.
One expectation is worth writing into the discussion. Guangsuan states that execution scope, delivery quantity, acceptance criteria and the review period should all be confirmed before cooperation, and that results are reviewed against real data such as Google Search Console rather than a single screenshot. The company also states that it was founded in 2019 and works through a corporate contract with a defined delivery scope.
What it does not promise
Doing SEO is not the same as buying an ad placement, and it does not mean a keyword will reach a set position on an agreed date. Guangsuan states this on its own pages, so read any proposal - including this vendor's - with that boundary in mind. What can be agreed is the work: the technical items, the content, the link scope and the review method. If a proposal trades those specifics for a position promise, that is the point to ask again.
FAQ
Should I average two disagreeing volume figures? No. Averaging hides the question. Find out whether the two runs used the same location, language, network and month range, then re-run both with matched settings. Overlapping results mean you cannot rank two terms by volume with confidence, and you may not need to.
Is a third-party volume number wrong? It is an estimate. Different databases report different figures for the same term, so use one tool consistently for relative comparisons and use Search Console for the queries your own site already appears for.
Do I need all three parts of a Google SEO service at once? Not necessarily. Whether you start with technical work, content or links depends on the target market, the budget and the current state of the site, and starting with the most important part and expanding based on measured performance is a legitimate approach.
How should we judge whether it is working? Look at search impressions and clicks first, then at the inquiry actions and lead sources on the page, and combine that with the sales team's view of lead quality. Attribution across platforms can overlap, so channel reports should not be added together as a customer total without checking.
Do the tools give the same numbers once the settings match? Not always. Ranges can overlap without being identical, and each vendor estimates from its own data. The point of the cross-check is to know whether the disagreement changes your decision, not to find one true number.
