在網頁內嵌入地圖的需求時常會用到，以下三種是最常見的方法：

• Google Maps Embed API (內嵌網頁)
• Google Static Maps API (靜態地圖圖片)
• Google Maps JavaScript API (動態地圖)

優缺點比較

方法 | 運作方式 | 優點 | 缺點
------------- | -------------
Google Maps Embed API | iframe 嵌入地圖 | 製作簡單且呈現動態呈現 | 嵌入 iframe 效能最差
Google Static Maps API | 靜態地圖圖片 | 效能最佳 | 只是一張圖片，無法縮放、互動
Google Maps JavaScript API | 參數串接地圖 | 客製化程度最高 | 串接資料需要有一定的程式能力

補充
嵌入 iframe 效能最差，是因為網頁雖然只發出一個請求取得 iframe 的資訊，但 iframe 這個地圖網頁裡又會發出了許多請求，像是取得定位資訊、附近地點、背景底圖......等，才有辦法呈現如此多的資訊，同時也會造成網頁負擔。

At the end of the day if you just want to keep it simple using the Google Maps Embed API is your best option available. There is some downsides in terms of customisation and loading times but if you’re looking for a simple solution embedding your map is by far the easiest to do.
