The answer to the question "Which one should do SEO first or GEO first?" is almost always "do both together, but the proportions are different." The reason is very practical: the AI engine needs to quote you in the answer only if it can capture and understand your page, and this is handled by the technical base of SEO. There is no pure alternative. What is really worth your time is how to divide the budget, which part will be effective first, and whether your buyer is typing keywords in Google at this moment, or has already asked a complete question in ChatGPT.
Why “SEO or GEO first” is a fake question
GEO and SEO share the same underlying set of conditions. HTML that can be crawled by crawlers, clean website structure, correct schema markup, fast enough server response - these are the basis of Google rankings, and are also the prerequisites for the AI engine to decide whether to include you as an answer source. A website that even Googlebot has difficulty reading will also be skipped by the AI crawler because it cannot get clean passages that it can safely quote. Therefore, the first step of any GEO project is to make up for the technical debt owed by SEO. There is no shortcut to this part.
The real difference between the two is the objective function. What SEO wants is rankings and clicks, and success or failure depends on the keyword position and the traffic it brings; GEO wants to be cited by generative answers and named by the model in the answer, and success or failure depends on the frequency and context in which AI mentions you. The same piece of content can serve both sides at the same time, but the writing method is different: when writing for SEO, it is designed for users to click in and read it; when writing for GEO, the AI should be able to cleanly extract a paragraph and put it directly into the answer, and the arguments, figures, and conclusions must be self-contained. Understanding this difference first can save your budget more than worrying about who comes first and who comes last.
First use three dimensions to judge your situation
Before you sort, answer three questions honestly. The answers to these three questions will directly determine which side you should focus on, rather than applying the proportions of others.
- Buyer search behavior: How often do your target customers use AI Q&A instead of traditional search? B2B SaaS technical decision-makers and developers are switching to AI significantly faster than traditional manufacturing procurement.
- Existing SEO foundation: If the website fails even basic crawlability, title level, and internal links, fix this first, and then GEO will have a foothold.
- Budget and time: When the budget is limited, priority should be given to overlapping tasks - it is much more cost-effective to write one piece of content at the same time so that it can be "ranked and attracted" than doing two lines each.
Prioritize by budget
Your budget determines how many fronts you can open at the same time. The following uses three common monthly content budget levels to explain how to roughly determine the proportion; the amount is a rough reference for the Taiwan B2B market, and the focus is on proportional logic rather than precise numbers.
- Under 50,000 per month: Don’t get distracted. Focus on writing 10 to 20 core topics into content that has a clear structure and can be quoted cleanly, so that SEO and GEO can be done at once. On the technical side, we only do the most basic crawlability and schema, and we don’t pursue advanced ones.
- 50,000 to 150,000 per month: SEO base (technical fixes plus theme clusters) accounts for about 60%, and GEO exclusive actions (question-and-answer content, quotable formats, Brand Radar visibility tracking) account for about 40%.
- More than 150,000 per month: can be divided into two lines in parallel. One continues to expand topic coverage and rankings, and the other focuses on AI engine visibility and citation rates, and begins to track the proportion of competing products in AI answers.
Prioritize by industry
Property determines "how far along" your buyer has come. There is actually only one benchmark for judgment: when making decisions, what proportion of your target customers have switched to AI Q&A instead of opening a search engine and slowly comparing. The higher the ratio, the higher the priority of GEO.
- B2B SaaS, developer tools, cloud infrastructure: Buyers are highly dependent on AI Q&A comparison solutions, and GEO should be equal to or even higher than SEO as soon as possible.
- Professional services, consultants, financial technology: Trust and source credibility are both important. SEO is responsible for establishing authority, and GEO is responsible for letting AI click on you in the recommendation list. The two go together.
- Traditional manufacturing, local services, long-tail e-commerce: most traffic still comes from Google and map search, SEO takes the lead, and GEO slowly lays the foundation with question and answer content and structured data.
A 90-day sequence you can follow
- Days 1 to 30: Work on technical debt first. Crawlability, schema, page speed, title level and internal links complete the foundation shared by SEO and GEO, so that every bit of content investment will not leak.
- Days 31 to 60: Pick 8 to 12 questions that buyers will really ask, and write them into answer-style content that can be quoted in one paragraph, taking into account search rankings and AI extraction.
- Days 61 to 90: Start measuring. In addition to keyword ranking, we also track the frequency and context of brand mentions by the AI engine, and use the data to decide which side to adjust the weight next season.
When should the focus clearly shift to GEO?
Don't hesitate when three signals appear. First, the search volume for your brand words or plan comparisons is decreasing, but the actual number of inquiries is still there - the traffic is migrating from Google to AI Q&A. Second, when you ask typical questions about your industry in ChatGPT and Perplexity, the answers repeatedly include competing products but not you. Third, the proportion of sales-side reports that “customers said they came to us after being recommended by AI” is increasing. These three things are evidence that the channel has been displaced. At this time, tilting the weight towards GEO is just following the money.
There is no standard answer to ranking, only "the proportion that suits your current situation." If you are not sure whether your technical foundation is strong enough, whether buyers have gone to the AI end, and which area should be invested first - instead of deciding the budget based on your feelings, it is better to read the data first. Tenten's 30-day GEO audit will take stock of your crawlability, citation status, and the proportion of competing products in AI answers, turning "what to do first" into a basis-based ranking.
