搜索引擎的用戶是網(wǎng)上搜索信息的人，客戶是廣告商。

目前所有的搜索引擎都是通過搜索競價(jià)廣告贏利的，不同搜索引擎的區(qū)別只在于競價(jià)廣告出現(xiàn)的位置、數(shù)目及是否比較清晰地標(biāo)明是廣告，其PPC本質(zhì)是一樣的。要想通過搜索廣告贏利，就必須有搜索用戶使用搜索引擎。

那站長們(以站長身份出現(xiàn)時(shí)而不是搜索用戶)說到底不是搜索引擎的用戶，更不是他們的客戶。搜索引擎并不欠站長或SEO人員什么東西，網(wǎng)站收錄不收錄，排名怎么樣，都是搜索引擎自己的事。就算我們的網(wǎng)站被完全刪除，所以沒必要抱怨的。

關(guān)鍵詞分布及網(wǎng)站架構(gòu)

baron 提問于 1年之前Zac老師您好，這兩天在看“seo實(shí)戰(zhàn)密碼”，因?yàn)橐呀?jīng)夠購買了域名和虛擬主機(jī)打算做公司的外貿(mào)網(wǎng)站。書中有涉及到關(guān)鍵詞分布和網(wǎng)站架構(gòu)的章節(jié)，有點(diǎn)小小疑惑想來咨詢。在關(guān)鍵詞分布中，您提到比較合理的整站關(guān)鍵詞布局類似于金字塔形式。在關(guān)鍵詞分組中您以核心關(guān)鍵詞云南旅游為例，次級關(guān)鍵詞為昆明旅游、麗江旅游等放在一級分類首頁。每個(gè)一級分類下還可以分二級。我們公司主營紡織面料，首頁

阿里云CDN設(shè)置80端口還是443端口

建議使用443端口，因?yàn)?43端口是HTTPS協(xié)議的默認(rèn)端口，可以提供更加安全的數(shù)據(jù)傳輸。同時(shí)，使用443端口也可以避免某些網(wǎng)絡(luò)環(huán)境中80端口被封鎖的問題。如果需要同時(shí)支持HTTP和HTTPS協(xié)議，可以將80端口重定向到443端口。

搜索引擎定義

搜索引擎是一種通過互聯(lián)網(wǎng)索引網(wǎng)站，并搜索相關(guān)內(nèi)容的工具，它可以通過語義分析或關(guān)鍵詞檢索的方式，從網(wǎng)站所存儲的數(shù)以億計(jì)的信息中，提供給用戶最相關(guān)的結(jié)果。常見的搜索引擎包括Google、百度、必應(yīng)等。
