有多大？ 1. 使用flash無法被搜索引擎抓取，使網(wǎng)站排名受到影響，SEO效果不好。 2. 如果使用flash，網(wǎng)站的結(jié)構(gòu)及導(dǎo)航將不易瀏覽，對(duì)用戶的體驗(yàn)也不佳。 3. 由于flash對(duì)用戶使用的體驗(yàn)不好，搜索引擎搜索到的網(wǎng)站也不能滿足用戶的需求，網(wǎng)站的排名也就被削弱。 4. 由于搜索引擎無法抓取flash，對(duì)SEO的影響是非常大的，用戶點(diǎn)擊搜索結(jié)果時(shí)，也無法訪問整個(gè)頁(yè)面，降低了網(wǎng)站的曝光率。

網(wǎng)站改版原來收錄的URL怎么辦？

網(wǎng)站改版有多種情況，有一種情況是：網(wǎng)站域名不變、網(wǎng)站系統(tǒng)要完全更換，內(nèi)容繼續(xù)在新系統(tǒng)使用。如果這個(gè)網(wǎng)站已存在一定時(shí)間，已有較多收錄量，那么原來收錄的那些URL該怎么辦呢？有兩個(gè)辦法來解決：1、在新系統(tǒng)或新服務(wù)器上，增加一項(xiàng)功能，把老的已收錄URL一一301給新的對(duì)應(yīng)內(nèi)容的URL上。如新系統(tǒng)采用搜外6系統(tǒng)，可在功能內(nèi)搜索下301找到該功能。2、如果1辦法無法實(shí)現(xiàn)，就是通過robots.txt文件屏蔽

如何判定網(wǎng)站降權(quán)？網(wǎng)站被降權(quán)的6種表現(xiàn)

1、關(guān)鍵詞排名下降：網(wǎng)站的關(guān)鍵詞排名變動(dòng)很大，原先排名靠前的關(guān)鍵詞現(xiàn)在難以排名前幾頁(yè)。 2、流量下降：進(jìn)入網(wǎng)站的自然流量明顯減少，訪問量和訪問時(shí)長(zhǎng)都有所下降。 3、收錄量下降：搜索引擎之前收錄的網(wǎng)站頁(yè)面或文章逐漸減少，有些已經(jīng)不再被搜索引擎收錄。 4、頁(yè)面鏈接減少：其他網(wǎng)站對(duì)你的頁(yè)面鏈接減少，原本鏈接到你的頁(yè)面的其他網(wǎng)站也不再鏈接到你的頁(yè)面。 5、抓取頻率降低：搜索引擎對(duì)你的網(wǎng)站頁(yè)面的抓取

SEO（搜索引擎優(yōu)化），是指對(duì)網(wǎng)站的內(nèi)容、結(jié)構(gòu)、鏈接等進(jìn)行相應(yīng)優(yōu)化，以提高網(wǎng)站的搜索引擎收錄度和搜索排名，最終提高網(wǎng)站的流量，達(dá)到增加客戶數(shù)量和訂單總量，實(shí)現(xiàn)公司推廣目標(biāo)的一種網(wǎng)絡(luò)營(yíng)銷技術(shù)。

SEO優(yōu)化師在對(duì)網(wǎng)站進(jìn)行全面系統(tǒng)性時(shí)，首先可從網(wǎng)站的SEO基礎(chǔ)數(shù)據(jù)開始入手，例如當(dāng)前網(wǎng)站收錄多少、收錄率如何、排名關(guān)鍵詞數(shù)量多少、排名關(guān)鍵詞類型等等，這些都是網(wǎng)站的基礎(chǔ)SEO數(shù)據(jù)，同時(shí)也是必須要做到心中有數(shù)的。SEO優(yōu)化師在了解完了SEO基礎(chǔ)數(shù)據(jù)之后，那么下一步就是了解網(wǎng)站關(guān)鍵詞布局，例如首頁(yè)TDK設(shè)定是否OK，列表頁(yè)布局了哪些關(guān)鍵詞、泛需求詞與長(zhǎng)尾關(guān)鍵詞是否合理，網(wǎng)頁(yè)標(biāo)題是否與主體內(nèi)容具備相關(guān)性
