Keyword Research and Targeting in the AI Era

What is Keyword Research and Targeting?

Through keyword research, we can understand what potential users truly care about, their preferences, and their ways of expression, thereby creating content that better aligns with their search habits. Good keyword research makes content more relevant to actual searches, increasing the chances of being recommended by search engines, and is crucial for both improving organic rankings (SEO) and optimizing paid advertising (SEM).

Keyword research involves analyzing data to find terms or phrases commonly used by users in search engines. These keywords are often not just single words, but more commonly search phrases with clear intent, such as:

  • “Best coffee machine for small apartments”
  • “High-performance laptops 2025”
  • “Which baby stroller brand is good”

Through keyword research, we can understand what potential users truly care about, their preferences, and their ways of expression, thereby creating content that better aligns with their search habits. Good keyword research makes content more relevant to actual searches, increasing the chances of being recommended by search engines.

Keyword Targeting: Helping Search Engines Understand Your Content Better

Keyword targeting is the process of naturally integrating the researched keywords into key positions on a page to improve the page’s visibility in search results. Keyword placement should not be about awkward repetition, but rather about making the page’s topic clear to both search engines and users.

Keywords should typically appear in the following locations:

  • Page Title
  • Beginning of paragraphs
  • URL links
  • Meta Description
  • Alt attributes of images
  • Appropriate natural positions within the content

For example, when a user searches for “portable washing machine for renters,” and you happen to offer a related product, then your page title, content, and description should clearly include this phrase, rather than just vaguely saying “washing machine recommendations.”

Precise keyword targeting not only helps search engines understand your content but also provides readers with the answers they are looking for.

Types of Keywords

Important Metrics for Keyword Research and Targeting

When conducting keyword research and targeting, selecting appropriate keywords depends not only on their relevance but also on a series of key metrics to judge their value. However, different platforms have different criteria and methods for evaluating keywords:

General Keyword Research Metrics

Metric NameDescription
Search VolumeAverage monthly search frequency of the keyword, measuring potential traffic scale
Keyword DifficultyThe level of competition for the keyword, usually related to the number of existing content, domain authority, etc.
Keyword Length/StructureLong-tail vs. head keywords, affecting precision and competition
Trend HotnessTime-series trend of search volume, helps determine if it’s seasonal or viral keyword
Search Intent TypeInformational, navigational, transactional, question-based, etc., crucial for content or ad matching

Platform-Specific Keyword Research Metrics

Platform TypeProprietary Metric NameDescription
Search EnginesCPC (Cost Per Click)Common on SEM platforms, measures the competition level of paid keywords
SERP FeaturesWhether rich text blocks are triggered, such as FAQs, images, videos, etc.
Video PlatformsTag Click-Through Rate, Watch Time Associated KeywordsUsed in YouTube/Douyin (TikTok) for algorithm to determine content relevance and recommendation weight
Title/Thumbnail Click-Through Rate (CTR)Evaluation of the attractiveness of video thumbnails and titles for search recommendations
E-commerce PlatformsCategory Hot Words (Browsing Terms)Hot terms in common buyer browsing paths and classification tags
Conversion Keywords (Purchase Trigger Terms)Keywords that lead to order placement, such as “discount,” “limited edition”
Social PlatformsHashtag VolumeFrequency and popularity of specific tags, such as #coffeelover
User Questions and Comments LanguageReal language data from communities like Reddit, Zhihu, suitable for question-based or colloquial keyword mining
App StoresASO Keyword WeightDifferences in weighting of name, subtitle, and keyword fields for search ranking
Install Conversion Rate Associated KeywordsWhich keywords lead to higher download conversion rates

On the surface, search engines, e-commerce platforms, and app stores have similar search behaviors: users enter keywords → the system returns matching results. However, they have fundamental differences in search goals, ranking logic, and user intent, so the reference metrics for keyword research will have a combination of overlap + differences:

DimensionSearch Engines (e.g., Google)E-commerce Platforms (e.g., Amazon)App Stores (e.g., App Store)
User Search IntentPrimarily “getting information,” also includes navigation, transactions, etc.Strong transactional orientation (finding something to buy)Finding a specific app, or fulfilling a specific usage need
Core Ranking MechanismRelevance + Authority + User Behavior SignalsRelevance + Sales Data + Price + Reviews + Conversion RateRelevance + Downloads + Ratings + Retention Rate + Keyword Match
Keyword Research GoalCapture search volume, difficulty, semantic relevance, optimize content structureTarget transactional keywords, competitor differentiator keywords, high-purchase-intent phrasesIdentify high-converting function words, competitor terms, category terms, long-tail demands
Keyword LifecycleLong-term or short-term coexistence (e.g., trending topics)Closely related to product inventory, promotion cyclesDynamically adjusts with version updates, feature changes, user feedback
Keyword Reference Metric DifferencesSearch volume, difficulty, intent, trendsSearch volume, competition <br> + Conversion keywords, category hot words, conversion rate wordsSearch volume <br> + ASO keyword weight, install conversion rate, user feedback keywords

How to Conduct Keyword Research?

With the rise of generative AI, many content creators and SEO practitioners are revisiting an old question: how exactly should we do keyword research? Past practices were well-established—selecting seed keywords, analyzing search volume, expanding long-tail keywords, controlling keyword density… the process was clear, the tools defined. But today, user search behavior has changed, becoming more conversational, more semantic, and more difficult to exhaustively enumerate.

Below, let’s compare the key differences between traditional keyword research methods and AI-driven approaches:

DimensionTraditional Keyword Research MethodsAI-Driven Keyword Research Methods
Starting PointBased on user behavior data + seed keyword expansion <br> Data sources include search engine auto-suggestions, tool recommendations, user search logs, etc.Based on natural language input and semantic modeling, AI can automatically identify keyword networks and search intent from a description/goal
Keyword Expansion MechanismStarting from seed keywords, rule-driven automatic recommendation or manual filtering expansionStarting from semantics, context-driven, can generate question-based, conversational, scenario-based keywords (non-explicit match terms)
Keyword Analysis DimensionsFocus: search volume, competition, CPC, keyword structure (head/long-tail)Enhanced: intent recognition, contextual relevance, search tone, user sentiment, conversational style, language variations
Keyword Structure UnderstandingRelatively flat structure, emphasizing head keywords + long-tail keywordsMore semantic structure: e.g., “functional terms,” “question terms,” “negative intent terms,” “pain point expressions,” “scenario-specific terms”
Keyword Generation MethodBased on user behavior/platform historical data statistics, leans towards static librariesBased on LLM generation: can generate semantic combinations and question-based expressions that users have not searched for but are highly potential
Tool Representatives (not absolute division)Ahrefs, SEMrush, Google Keyword Planner, AlsoAsked, AnswerThePublic, etc.Above tools + Frase, SEO.ai, ChatGPT (for keyword suggestions), WriterZen, NeuronWriter, Perplexity, etc.
Tool Capability DifferencesRelies on inputting keywords to trigger recommendation results, more for data query and filteringCan generate keywords and build content structure by inputting goals or user intent, supports intelligent clustering and summarization
Keyword-Content ConnectionKeywords → article structure (word frequency, headings, paragraph placement)User intent → search path → content phrasing, emphasizing natural language expression and semantic coverage
Keyword Research Role ChangeSEO specialist/content planner leadsPlanner + AI operator equally important, content creators can directly invoke AI to generate keyword frameworks
Keyword Coverage EfficiencyLong-tail keywords rely on manual supplementation or tool enumerationAI can automatically generate rich semantic variations and user language versions, improving efficiency several times over
Keyword Content MatchEmphasizes technical parameter matching (e.g., word frequency, density)More emphasis on semantic fluency and user intent response, stressing naturalness, conversationality, pragmatic consistency

How to Target Keywords?

Finding keywords is just the first step. What truly determines content effectiveness is how these words are used on the page, and whether they accurately respond to user search intent. In the past, we relied on experience to control the placement and frequency of keywords. Today, AI is beginning to help us understand “what users actually want to see” and embed keywords naturally into content:

DimensionTraditional Keyword Targeting MethodsAI-Driven Keyword Targeting Methods
Core Targeting LogicBased on keyword-to-page content match, optimizing placement and frequencyBased on user search intent and content semantic fit, optimizing context and experience. AI can even predict what a user might search for next, enabling proactive keyword placement.
Keyword Distribution MethodManual control of keyword placement in title, H tags, first paragraph, first sentence of paragraphs, URL, meta description, etc.AI automatically determines where keywords should appear in which paragraphs, tones, and phrasing based on semantic structure, aiming for natural language integration
Page Matching MethodKeyword → page content, “write around the keyword”User intent → content → covering related keyword clusters, “problem-solving centered”
Keyword-Intent AdaptationRely on experience to judge the intent behind keywords, prone to subjective biasLLM models can identify intent levels (e.g., informational/comparative/transactional) and generate matching phrasing
User Search Path UnderstandingUnderstand needs on a keyword-by-keyword basisUnderstand needs on a search path basis (e.g., “learn → compare → choose → buy”) and dynamically adjust keyword placement
Content Type MatchingOne keyword per page, multiple landing pages for different keywordsOne page, multiple intents, supporting coexistence of multiple keywords. AI can recommend modular content structures (e.g., FAQ + product comparison + review aggregation)
Targeting in Ad CampaignsSelected keywords + bidding, matching ad copy with landing pagesAI can generate the most relevant keyword sets and ad copy based on ad goals and user intent (e.g., Performance Max + AI animated content)
Adapting Content FormsPrimarily for text-based pagesAdapts to rich media, short videos, voice search, AI assistant search, supports cross-media expression consistency
Monitoring and OptimizationManually observe keyword ranking changes and click dataAI can track keyword → content → behavior paths, automatically identify “semantic off-track points” and suggest optimization

Frequently Asked Questions (FAQ)

Q1: Should I primarily focus on head keywords or long-tail keywords?

A1: You should focus on both, but with different strategies.

  • Head Keywords: High search volume, intense competition, can bring significant potential traffic, but achieving rankings and conversions is difficult and costly. Typically used for brand building and acquiring high-value traffic.
  • Long-tail Keywords: Relatively smaller search volume, but more precise search intent, less competition, and usually higher conversion rates. Cumulatively, they can bring considerable targeted traffic.

Recommendation: Initially, focus on long-tail keywords to more quickly achieve rankings and conversions. As website authority increases and budget allows, gradually compete for head keywords.

A2: No. The core principle of keyword research is understanding user needs and search behavior, which applies to any platform with search functionality. Whether it’s search engines like Google and Baidu, e-commerce platforms like Amazon and Taobao, video platforms like YouTube and Douyin (TikTok), or app stores like Apple App Store, users employ keywords to find information, products, or services.

Q3: Will AI tools completely replace manual keyword research?

A3: Not in the short term, but AI will become an indispensable assistant. AI has a huge advantage in rapidly generating large numbers of keywords, identifying semantic connections, analyzing search trends, and understanding user intent, greatly improving efficiency. However, human strategic judgment, industry insight, understanding of brand context, and capturing subtle user emotions are still aspects that AI cannot fully replace. The best approach is to use AI as a powerful assistant, allowing human experts to focus on higher-level strategic decisions and creative content.

Q4: How often should I conduct keyword research and update my content?

A4: Keyword research and content updates are continuous processes with no fixed schedule, but here are some guiding principles:

  • Before initial content publication: Conduct thorough and in-depth keyword research.
  • Regular review (every 3-6 months): Check keyword rankings, traffic, and conversion data to see if new popular keywords have emerged, or if existing keywords are performing poorly.
  • When market or product changes occur: When new products are launched, business expands, or significant market trends emerge, keyword research needs to be revisited.
  • Competitor dynamics: Pay attention to which keywords competitors are performing well on, and look for new opportunities.

Continuous keyword optimization is key to maintaining content competitiveness and acquiring traffic.
