We need to produce article without title, following constraints: 6-8 paragraphs, each 150-250 characters? Actually 150-250 words? It says 150-250字 (characters? Chinese characters count). Likely Chinese characters count. We need total 1500+ characters, min 1050. 6-8 paragraphs, each 150-250 characters. Let's aim for 7 paragraphs of about 210 characters each = 1470 characters, meets >1500? Actually 210*7 = 1470, that's less than 1500. Need at least 1500 characters. If we use 8 paragraphs of 200 chars = 1600. Must be 1500+ characters. So we need total >=1500. Let's produce 8 paragraphs, each about 200-210 characters. That gives around 1680 characters. Ensure each paragraph 150-250 characters. We'll count roughly.

We need natural, conversational style, no AI words. Avoid list, avoid formalities. Provide practical advice, avoid repetition.

Structure: 8 paragraphs.

Paragraph 1: intro, hook, mention title concept. ~200 chars.

Paragraph 2: first criteria: portfolio and case studies. ~200 chars.

Paragraph 3: second criteria: team skill and tech stack. ~200 chars.

Paragraph 4: third criteria: communication and after-sales. ~200 chars.

Paragraph 5: fourth criteria: price transparency and contract clarity. ~200 chars.

Paragraph 6: fifth criteria: client reviews and reputation. ~200 chars.

Paragraph 7: common pitfalls and how to avoid them. ~200 chars.

Paragraph 8: concluding call to action, tie back to title. ~200 chars.

Need to ensure each paragraph 150-250 Chinese characters. Let's approximate.

We'll write paragraphs with about 200 characters each. Let's craft.

Count characters manually? Approx.

Paragraph 1: "国内网站建设公司哪家强，挑选攻略助你避坑" is title, but we cannot use title in article? The article should start with intro that echoes title. We can mention "选一家靠谱的国内网站建设公司，可不是件容易事". That's about 20 chars? Need ~200 characters. Let's write longer.

I'll craft each paragraph ~200 characters.

Let's draft paragraph 1:

"选一家国内网站建设公司，真不是随便点个名字就能事事顺的。很多企业在一开始就被花哨的宣传吸引，结果项目卡壳、交付延期，甚至功能跑偏。其实，挑选前先弄清楚自己的需求、预算和期望值，才是避开坑点的第一步。下面就带你一步步拆解，怎么在众多公司中找到真正靠谱的伙伴。"

Now count characters: Let's count roughly. Each Chinese character counts as one. Let's count quickly:

选(1)一2家3国4内5网6站7建8设9公10司11哪12家13强14，15挑16选17攻18略19助20你21避22坑23？24... Actually we need 150-250 characters, not just 30. So need longer.

Paragraph 1 ~200 characters. Let's write about 200 characters.

"想在国内网站建设公司中脱颖而出，光看官网的宣传可不够，得先理清项目的核心目标、功能需求以及预算范围。很多企业在找公司的时候，只盯着价格或是案例堆砌，却忽略了团队的实战经验和沟通效率。先把需求文档写得尽可能细致，再根据这份文档去筛选合作伙伴，才能避免后期的返工和追加成本。"

Now count characters: Let's count roughly:

想1在2中3国4内5网6站7建8设9公10司11中12脱13颖14出15，16光17看18官19网20的21宣22传23可24不25够26，27得28先29理30清31项32目33的34核35心36目37标38、39功40能41需42求43以44及45预46算47范48围49。50很多51企52业53在54找55公56司57的58时59，60只61盯62着63价64格65或66是67案68例69堆70砌71，72却73忽74略75了76团77队78的79实80战81经82验83和84沟85通86效87率88。89先90把91需92求93文94档95写96得97尽98可能99细100致101，102再103按104这105份106文107档108去109筛110选111合112作113伙114伴115，116才117能118避119免120后121期122的123返124工125和126追127加128成129本130。 That's about 130 characters. Need 150-250. Need to add more.

Add more sentences: "比如，是否需要电商功能、会员体系还是多语言支持，这些细节决定了后续技术选型和开发节奏。只有把这些问题提前梳理清楚，才能在对比公司时做出精准的判断。"

Now count added: "比如，是否需要电商功能、会员体系还是多语言支持，这些细节决定了后续技术选型和开发节奏。只有把这些问题提前梳理清楚，才能在对比公司时做出精准的判断。" Let's count characters roughly:

例1如2，3是4否5需6要7电8子9商10功11能12、13会14员15体16系17还18是19多20语21言22支23持24，25这26些27细28节29决30定31了32后33续33? Wait miscount. Let's just approximate length ~80 characters. So total maybe ~210. Good.

Thus paragraph 1 around 210 characters.

Paragraph 2: talk about portfolio and case studies.

Write ~200 characters.

"看公司的作品集是基础，但别光看表面光鲜的页面。真正有价值的，是那些能够体现业务增长、用户转化率提升的真实案例。找那些和自己行业相近的项目，观察技术实现的深度和交互设计的细腻度。如果对方只能提供模糊的数据，或者没有可量化的效果，那可能只是在做噱头。深入研究后，你会发现有些公司虽然报价低，但实际交付的体验要差很多。"

Count characters approx? Let's approximate ~200.

Paragraph 3: team skill and tech stack.

"团队的技术栈和经验水平直接决定项目质量。不是所有公司都能熟练使用最新的前端框架或后端微服务架构，尤其是需要高并发、数据安全的业务。可以让对方展示团队成员的项目经验、熟悉的编程语言以及对云服务的了解程度。如果他们只会说‘我们用过XX技术’，却无法提供具体的代码片段或架构图，那大可提前打退主意。"

Paragraph 4: communication and after-sales.

"项目过程中，沟通是否顺畅往往决定最终满意度。有些公司在谈判阶段很热情，等到签约后就消失，或者在开发中频繁的进度更新让你感到焦虑。建议提前约定周会或进度报告的频率，明确问题反馈的渠道。后期维护和功能迭代同样重要，别只看上线那一刻的亮眼，要关注长期的技术支持和迭代能力。"

Paragraph 5: price transparency and contract clarity.

"价格透明度是避坑关键。很多公司在报价时只给出一个模糊的数字，后期却会加项各种‘额外功能’或‘加急费用’。在正式合作前，务必把需求、功能列表、测试环节以及验收标准全部写进合同里。付款节点也要分清，避免一次性打款导致后期失去监督。这样既能保证预算可控，也能在出现争议时有据可依。"

Paragraph 6: client reviews and reputation.

"口碑和评价往往比广告更真实。可以在行内论坛、社交媒体或者第三方平台上查找合作过的客户的真实反馈，尤其是那些和你同行业的伙伴。注意观察是否有长期合作的记录，或者是否在项目出现问题后能够快速响应。如果大量评论提到‘拖延’‘沟通不畅’‘返工多’，那可别轻易踩坑。相反，那些项目进度稳、售后靠谱的公司，往往在
