圖片SEO是指通過優(yōu)化網(wǎng)站上的圖像來提高其在搜索引擎中的可見度。所以如何優(yōu)化你的圖像得到正確的流量就變得越來越重要。
一、圖片SEO的概念
1. 什么是圖片SEO？
圖片SEO是指通過優(yōu)化網(wǎng)站上的圖像來提高其在搜索引擎中的可見度。它旨在幫助網(wǎng)站將其內(nèi)容顯示在由Google、Bing或Yahoo!創(chuàng)建的有效圖像搜索中。
2. 圖片SEO為什么重要？
由于大多數(shù)人都使用Google Images來尋找信息，而不是新聞或博客文章，所以如何優(yōu)化你的圖像得到正確的流量就變得越來越重要。此外，當(dāng)人們想要看到一個話題時，他們通常會首先去看相關(guān)圖片。如果你能夠?qū)⒛愕膬?nèi)容準(zhǔn)確地呈現(xiàn)出來并改進你的可視性，那么獲得流量就會變得容易得多。
二、如何實施圖片seo?
1. 選擇合適格式
雖然沒有一個“最好”格式作為 SEO 來使用, 不過 JPEGs 和 PNGs 都是相當(dāng)理想之選, 這些格式都能夠生成高質(zhì)量, 有效節(jié)省存儲大小(file size) 的文件. GIFs 此前已作為 SEO 用途而廣泛使用, 不過隨之而來便是 GIFs 大尺寸(large file sizes) 等問題; SVG (Scalable Vector Graphics) 正在日益流行, 具有獨立性(independence), 高度可擴展性(scalability), 超少存儲大小(small file size).
2. 選用含感詞/詞語/關(guān)鍵字/hashtag 的文字
在 Google Image Search 中, 搜尋者能夠使用 “Alt Text” (alternative text) , “Title Text” (title attribute text), “Caption Text” (caption text) , “Description Text” (description text ) , "Hashtags" (#hashtags ) . Alt texts and title attributes are the most important for image optimization as they help search engines understand what an image is about and how it relates to other content on your website or blog post. Captions and descriptions can also be used to provide additional context for images that may not be immediately obvious from the alt or title tags alone. Hashtags can also be used to make images more discoverable in social media platforms such as Instagram and Twitter where users often use hashtags when searching for relevant content related to their interests or topics of discussion..
3. 針對 Mobile-Friendly Optimization
Mobile-friendly optimization is becoming increasingly important with the rise of mobile devices being used to access websites and online services across all industries including ecommerce stores, blogs and news sites etc.. To ensure that your images are optimized correctly for mobile devices you should consider using responsive design techniques such as srcset which allows you to specify different versions of an image depending on the device type being used by a user so that they get served with an appropriately sized version of the image based on their screen resolution.. Additionally you should also consider using lazy loading techniques which allow you to only load images when they come into view rather than preloading them all at once which can significantly reduce page load times especially if there are many large files present on a single page.. Finally it's worth noting that some browsers may not support certain types of formats so it's always best practice to include multiple versions in order for maximum compatibility across all devices types..
