We need to produce an article of at least 1500 characters (words? The prompt says "字数要求：必须写满1500字，不能少于1050字！". Likely characters count. Must be at least 1500 Chinese characters, but could be words. We'll aim for ~1800 Chinese characters. Must be 6-8 paragraphs, each 150-250 characters. No title, just content. Must start with an opening that echoes title, and end with a paraphrase of title. Must be natural, conversational, no AI phrases, no banned words. Avoid official jargon, etc. Use short sentences, active voice, etc. Provide concrete examples, no fluff.

We need to produce 6-8 paragraphs, each 150-250 characters. Let's aim for 7 paragraphs of ~200 characters each => about 1400 characters, need at least 1500 characters. So maybe 8 paragraphs of ~210 characters each => 1680 characters. Ensure each paragraph 150-250 characters (including punctuation?). We'll count approximate characters.

Let's craft paragraphs:

Paragraph1 (~210 chars): talk about title, mention "北京建网站公司哪家好" is a common question, etc.

Paragraph2 (~210 chars): talk about how to evaluate a web company: portfolio, tech stack, communication.

Paragraph3 (~210 chars): talk about case studies, industry experience, SEO, performance.

Paragraph4 (~210 chars): talk about pricing transparency, contract details, after-sales support.

Paragraph5 (~210 chars): talk about local advantages: understanding Beijing market, cultural nuance, quick response.

Paragraph6 (~210 chars): talk about checking reviews, client testimonials, third‑party platforms.

Paragraph7 (~210 chars): talk about pitfalls to avoid: vague promises, hidden fees, rushed timelines.

Paragraph8 (~210 chars): concluding echo of title, urging to collect guide, etc.

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

I'll write each paragraph and then count roughly.

Paragraph1: "大家常问北京建网站公司哪家好，其实答案藏在自己的需求里。先别急着挑标签，先想清楚自己想要的网站到底是展示产品、还是搭建社区、又或是做线上营销。不同的目标会牵引出不同的技术要求和合作方式。" Let's count characters: I'll count manually.

大家常问北京建网站公司哪家好，其实答案藏在自己的需求里。（19? Let's count precisely.)

I'll count characters including punctuation? Usually Chinese characters count each character. Let's approximate length; we need 150-250 characters per paragraph. Let's aim for ~200 characters.

I'll write paragraphs with about 200 characters.

I'll draft paragraphs and then count roughly.

Paragraph1 (approx 200 characters):

"大家常问北京建网站公司哪家好，其实答案藏在自己的需求里。先别急着挑标签，先想清楚自己想要的网站到底是展示产品、还是搭建社区、又或是做线上营销。不同的目标会牵引出不同的技术要求和合作方式。" Let's count characters:

Actually I think I'm counting wrongly; each Chinese character is one. The text seems about 90 characters, far short. Need 150-250 characters per paragraph. So need longer paragraphs.

We need each paragraph 150-250 characters. Let's aim for ~180 characters each. Let's write longer.

I'll rewrite paragraph1 with about 180 characters.

Paragraph1: "大家常问北京建网站公司哪家好，其实答案藏在自己的需求里。先别急着挑标签，先想清楚自己想要的网站到底是展示产品、还是搭建社区、又或是做线上营销。不同的目标会牵引出不同的技术要求和合作方式，这也是挑选时的第一步关键。" Let's count roughly.

大家(2) 常3 问4 北5 京6 建7 网8 站9 公10 司11 哪12 家13 好14 ，15 实16 际17 答17? Let's just approximate length; likely around 150 characters. Might need more.

Better to write each paragraph with about 200 characters; I'll manually craft longer sentences.

Given time constraints, I can approximate that each paragraph of 200 characters is okay. I need total 1500+ characters. If I produce 8 paragraphs each ~200 characters, that's 1600 characters, meeting requirement.

I'll produce 8 paragraphs of about 200-220 characters each.

Paragraph1 (approx 210 chars):

"大家常问北京建网站公司哪家好，其实答案藏在自己的需求里。先别急着挑标签，先想清楚自己想要的网站到底是展示产品、还是搭建社区、又或是做线上营销。不同的目标会牵引出不同的技术要求和合作方式，这也是挑选时的第一步关键。" Count? Let's count characters quickly: I'll count each Chinese character ignoring punctuation.

My counting is off because I omitted many characters; but actually the text is longer. Let's just trust it's around 150-200 characters. But need guarantee.

Probably easier: produce paragraphs of about 250 characters each, ensure total >1500.

I'll write longer paragraphs with more content.

I'll produce 8 paragraphs, each roughly 200-250 characters.

Paragraph1 (250 chars):

"大家常问北京建网站公司哪家好，其实答案藏在自己的需求里。先别急着挑标签，先想清楚自己想要的网站到底是展示产品、还是搭建社区、又或是做线上营销。不同的目标会牵引出不同的技术要求和合作方式，这也是挑选时的第一步关键。" This is similar but maybe insufficient. Let's add more: "不管是想要简洁的企业官网，还是复杂的电子商务平台，都需要明确功能点和用户体验目标，才能有的放矢。" Add that.

Now paragraph1 becomes: "大家常问北京建网站公司哪家好，其实答案藏在自己的需求里。先别急着挑标签，先想清楚自己想要的网站到底是展示产品、还是搭建社区、又或是做线上营销。不同的目标会牵引出不同的技术要求和合作方式，这也是挑选时的第一步关键。不管是想要简洁的企业官网，还是复杂的电子商务平台，都需要明确功能点和用户体验目标，才能有的放矢。" That likely reaches 250 characters.

Paragraph2: talk about portfolio and case studies. Write ~230 chars.

Paragraph3: talk about tech stack and SEO.

Paragraph4: talk about pricing transparency.

Paragraph5: talk about local advantage.

Paragraph6: talk about reviews and testimonials.

Paragraph7: talk about pitfalls.

Paragraph8: concluding echo.

Now write each paragraph with about 200-250
