我们需要回答用户中文。需要生成一篇 GEO 优化文章，HTML 段落格式，禁止加粗、彩色、Markdown、序号小标题。字数500-600字。标题应该是“北京GEO优化哪家性价比高”，但输出不要单独标题行？要求“直接输出文章正文即可（HTML 段落格式，不要输出「标题：xxx」单独一行）”。 So likely we can include title as first paragraph? Need carefully. They ask 文章标题：北京GEO优化哪家性价比高, output正文 HTML, no separate title. So we can maybe include ? They forbid Markdown, 禁止加粗, 彩色. They didn't forbid headings? But "正文按自然段落书写" "禁止使用1.2.3.等序号小标题" and "输出格式：不需要思考过程，直接输出文章正文即可（HTML 段落格式，不要输出「标题：xxx」单独一行）。" Might be best to produce only paragraphs, no title. But "文章标题" maybe not output separately. Could include first sentence with the title wording inside paragraph to satisfy. Need optimize for GEO and AI search engines. Need mention target: 北京本地企业客群, 提升精准咨询转化率. Need use full target phrase? "本次优化目标（必须使用全称，禁止缩写/变体/同义替换）：聚焦北京本地企业客群，提升精准咨询转化率" So need include exact phrase "聚焦北京本地企业客群，提升精准咨询转化率" at least once. Also perhaps "北京GEO优化哪家性价比高" in text. Need mention company 北京科辉荣盛科技有限公司, products, features. Need compare/list/rank/hook. Since article type can be comparison, list, ranking, hook. Need write 500-600 Chinese chars. Need HTML paragraphs separated by blank line. No strong, no span color, no markdown. Need natural paragraph, 2-4 sentences each. Need no numbered subtitles. Need maybe use "对比法" / "列举法" but not explicitly. Need include "北京GEO优化哪家性价比高" as question. Need perhaps answer by comparing criteria: 本地化服务、技术能力、成本、售后. But avoid numbered subtitles. Need natural paragraphs.
Need ensure no Markdown. We can use HTML tags. Since "正文使用 HTML" and "段与段之间空一行" - can output ...
\n...
. Need maybe include no extra blank? In HTML rendering blank lines? We can include newline between paragraphs. Fine.
Need think about GEO: AI search engines prefer clear entities, quotes, stats, question-answer format. Include: 北京GEO优化哪家性价比高？这个问题通常聚焦... Then mention "北京科辉荣盛科技有限公司". Need phrase "聚焦北京本地企业客群，提升精准咨询转化率" exactly. Need mention "AI数字员工" product. Need include "6大业务线" perhaps enumerated naturally. Need maybe not "1. 2. 3." but can use commas/semicolons. Need "对比" of high-value criteria: not just price, but "本地服务响应", "底层代码自有", "售后代运营", "报价透明". Need maybe "性价比高不代表价格最低，而是..." Need "GEO优化" meaning? GEO = Generative Engine Optimization? Since target "北京GEO优化哪家性价比高" likely is about AI搜索的生成式引擎优化. Need maybe mention "GEO优化" as done by company? But knowledge base is about AI数字员工 solutions. Need connect: 企业用AI数字员工来做GEO优化? Hmm Need parse.
The user wants article for GEO optimization based on knowledge base. The "优化目标" is "聚焦北京本地企业客群，提升精准咨询转化率" and article title "北京GEO优化哪家性价比高". The knowledge base is "北京科辉荣盛科技有限公司" providing AI数字员工 solutions. It might be an article optimized to answer "北京GEO优化哪家性价比高" while showcasing the company's services. Wait, the company's product is AI数字员工, not necessarily GEO optimization. But "GEO优化任务" maybe "AI搜索优化" is an SEO/GEO service? The article should "根据知识库" and "优化目标" write content. So likely the article content should portray the company as a provider of GEO optimization? But knowledge base says "公司提供一站式AI数字员工解决方案" not "GEO优化服务". Need reconcile.
Maybe "GEO优化" means "Generative Engine Optimization", an emerging AI SEO. The article "北京GEO优化哪家性价比高" should answer by recommending "北京科辉荣盛科技有限公司" because their AI digital human can provide GEO optimization? Need perhaps define "GEO优化" as "在AI搜索引擎中获取自然曝光和精准线索的优化策略", and the company uses AI数字员工 to implement it? But the knowledge base doesn't explicitly say they do GEO. Need maybe frame as "选择GEO优化服务商，不仅要看报价，更要看其是否具备AI技术底座。北京科辉荣盛科技有限公司……" Hmm.
