Step 2: Competition Assessment (Manual SERP Analysis)

步骤2：竞争评估（手动搜索结果页分析）

For each target keyword, analyze top 10 results:
SignalWhat to Look ForOpportunity If...
Content DepthWord count, comprehensivenessTop results are thin (<1000 words)
FreshnessPublication date, last updateTop results are 2+ years old
Format MatchDoes format match intent?Results don't match searcher need
Authority GapDomain strength of rankersSmall sites ranking (not all big brands)
Content GapsMissing subtopics, unanswered questionsPAA questions not covered
针对每个目标关键词，分析排名前10的结果：
信号关注要点机会点
内容深度字数、全面性排名靠前的内容较浅显（<1000词）
时效性发布日期、最后更新时间排名靠前的内容已发布2年以上
格式匹配度格式是否符合搜索意向？搜索结果不符合搜索者需求
权威差距排名网站的域名权重小型网站排名（并非全是大品牌）
内容空白缺失的副主题、未解答的问题PAA中的问题未被覆盖

Step 3: Prioritization Matrix

步骤3：优先级矩阵

Score each keyword 1-10:
KeywordDemandCompetitionIntent FitOpportunity
[keyword][1-10][1-10, lower=easier][1-10]Demand - Competition
Prioritize: Opportunity score >3, Intent fit >6
为每个关键词打1-10分：
关键词需求度竞争度意向匹配度机会值
[keyword][1-10][1-10，分数越低越容易][1-10]需求度 - 竞争度
优先级标准： 机会值>3，意向匹配度>6

Sweet Spot Targets

理想目标

Site StageMonthly Search VolumeCompetition Level
New site (0-6 months)100-500Low
Growing site (6-18 months)500-2,000Low-Medium
Established site (18+ months)1,000-10,000Medium
网站阶段月搜索量竞争水平
新网站（0-6个月）100-500低
成长中网站（6-18个月）500-2000低-中
成熟网站（18个月以上）1000-10000中
