We need to write article body only, no title. Must be 1500+ characters (Chinese characters), each paragraph 150-250 characters? Wait they said "每段150-250字". That likely means each paragraph 150-250 words? Actually Chinese "字" usually means characters, but they also said "字数要求：必须写满1500字，不能少于1050字！". So overall must be at least 1500 characters (words?). They also say each paragraph 150-250字 (characters). If we have 6-8 paragraphs, each 150-250 characters, total would be 900-2000 characters. They require at least 1500 characters, so we need maybe 7 paragraphs of about 215 characters each gives ~1505 characters. That fits. Must be natural, conversational, no AI-sounding words. Must avoid banned phrases. Ensure no intro or conclusion with headings. Must not use "" etc. Must not use transition words like "". Must not use "然而" maybe okay? It's not banned but it's transitional; but they said "段落之间用逻辑衔接，不用过渡词衔接". So we should not use explicit transition words like "" "" "". Use logical flow without explicit transition words. Use short sentences, active voice.

Structure: 6-8 natural paragraphs, each 150-250 characters. Must open with hook referencing title. Title is "网站设计如何选对网络公司，这5个关键点决定成败". The opening paragraph should echo that title and introduce the topic. Then discuss key points (5). Must cover 5 key points, each maybe in separate paragraphs? Could be 5 paragraphs each covering a point, plus intro and conclusion maybe making 7 paragraphs. That fits 6-8 paragraphs.

We need to ensure each paragraph 150-250 characters (Chinese characters). Let's aim for about 200 characters each. 7 paragraphs => 1400 characters, need at least 1500 characters. So maybe 8 paragraphs of ~190 characters each = 1520 characters. Let's produce 8 paragraphs.

Paragraph count: 8 paragraphs.

Paragraph 1: Opening, echo title, introduce that choosing right web company matters, mention 5 key points.

Paragraph 2: First key point: 目标受众与品牌定位（or 说清楚需求). Need to keep length ~180-200 characters.

Paragraph 3: Second key point: 设计风格与用户体验（或 SEO).

Paragraph 4: Third key point: 项目案例与口碑.

Paragraph 5: Fourth key点: 技术能力与交付周期.

Paragraph 6: Fifth key点: 售后服务与合作沟通.

Paragraph 7: Summarize how these points affect success, maybe tie back to title.

Paragraph 8: Final call to action or concluding thought, still maintain natural tone.

Need to avoid banned words: "、" etc. So we cannot use "". We can just write sentences directly. Use short sentences, active voice.

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

I'll draft each paragraph and count characters manually (approx). Chinese characters count includes punctuation? Usually count characters only, punctuation not counted? We'll approximate.

Paragraph 1 draft: "想要让公司官网在网络上站稳脚跟，光靠漂亮的模板可不够。本文把目光拉回到最核心的问题——怎么挑到真正能把业务推进的网络公司。下面这几个关键点，往往就是决定成败的分水岭。" Let's count characters (including punctuation?). Let's count characters ignoring punctuation maybe. I'll manually count:

想要(let1) 让(let2) 你3? Actually Chinese counting: "想要让公司官网在网络上站稳脚跟，光靠漂亮的模板可不够。" Let's count characters (including punctuation? We'll count characters ignoring punctuation). I'll count roughly: 想(1) 要2 让3 我4 们5 官6 网7 在8 网9 络10 上11 站12 稳13 脚14 跟15 ，16 光17 靠18 漂19 亮20 的21 模22 板23 可24 不25 够26 。 That's 26 characters. Then "本文把目光拉回到最核心的问题——怎么挑到真正能把业务推进的网络公司。" Count: 本1 文2 把3 目4 光5 拉6 回7 到8 最9 核10 心11 的12 问13 题14 —— maybe counts as two characters? but ignore. 怎1 么2 能3 到4 真5 正6 能7 把8 业9 务10 推11 进12 的13 网14 络15 公16 司17 。 That's about 17 more, total ~43. Then "下面这几个关键点，往往就是决定成败的分水岭。" Count: 下1 面2 这3 几4 个5 关6 键7 点8 ，9 往10 样11 就12 是13 决14 定15 成16 胜17 的18 分19 水20 岭21 。 That's 21. So total paragraph ~64 characters, too short. Need 150-250 characters per paragraph. So we need longer paragraphs.

Thus we need to write paragraphs of about 180-220 characters. Let's aim for ~200 characters each.

We'll need to write longer sentences.

Let's craft paragraphs with about 200 characters.

I'll write each paragraph and then count approximate characters.

Paragraph 1 (intro): Need about 200 characters.

"在竞争日益激烈的网络空间里，企业官网已经不再是单纯的展示窗口，而是直接牵动流量、转化率乃至品牌口碑的关键入口。于是，怎么挑一家靠谱的网络公司，成了每个决策者必须面对的硬实战。本文不再泛泛而谈，聚焦于那些真正能左右项目成败的五大关键点，帮助你在众多报价和宣传背后，快速辨别出真正值得信赖的合作伙伴。"

Now count characters (excluding punctuation?). Let's count roughly:

在(1) 竞2 争3 日4 益5 激6 烈7 的8 网9 络10 空11 间12 里13 ，14 企15 业16 官17 网18 已19 不20 再21 是21? Actually "已经" two characters. Let's count properly: "已经" is two characters. Let's count each Chinese character ignoring punctuation.

I'll write the paragraph with characters and count.

"在竞争日益激烈的网络空间里，企业官网已经不再是单纯的展示窗口，而是直接牵动流量、转化率乃至品牌口碑的关键入口。于是，怎么挑一家靠谱的网络公司，成了每个决策者必须面对的硬实战。本文不再泛泛而谈，聚焦于那些真正能左右项目成败的五大关键点，帮助你在众多报价和宣传背后，快速辨别出真正值得信赖的合作伙伴。"

Now count characters (including punctuation? We'll count characters only, ignoring punctuation maybe). Let's count roughly:

在1 争2 争3 日4 益5 激6 烈7 的8 网9 络10 空11 间12 里13 企14 业15 官16 网17 已18 不19 再20 是21 单22 纯23 的24 展25 示26 窗27 口28 而29 是30 直31 接32 牵33 动34 流35 量36 、? punctuation not count, but we can ignore. 转37 化38 率39 乃40 至41 品42 牌43 口44 碑45 的46 关47 键48 入49 口47? Actually "关键入口" two characters: 关48 键49 入50 口51. So continue: 于是，怎么挑一家靠谱的网络公司，成了每个决策者必须面对的硬实战。 Let's continue counting: 于52 是53 这53? Wait we need systematic counting. This is tedious. But we can approximate length. The paragraph likely around 200-250 characters. Let's trust it's around 200.

But we need each paragraph 150-250 characters. So we can aim for about 200 characters each. It's okay if we overshoot a little as long as each is within range. But we must ensure not too short (<150) or too long (>250). We can approximate.

Better approach: Write paragraphs of about 180-200 characters, then assume they meet requirement.

We'll produce 8 paragraphs each roughly 190-200 characters. We'll not count exactly but try to be within range.

We must avoid banned words: "、". So we cannot use these transitional words. We can just write sentences directly.

We must not use "然而" maybe okay but it's transitional; they said "不用过渡词衔接". So better avoid "然而". Use direct sentences.

We must not use "让我们" etc. So avoid that.

We must not use "不可或缺" etc. Avoid those.

We must not use "值得关注" maybe okay but it's a phrase
