Eine einfache Python-Funktion zum Abfragen von Baidu-Keyword-Rankings, Funktionen:

1. UA Random

2. Einfache und bequeme Bedienung, einfach getRank (Keyword, Domainname)

3. Kodierungskonvertierung. Es sollte kein Problem mit der Codierung geben.

4. Reichhaltige Ergebnisse. Nicht nur das Ranking, sondern auch der Titel, die URL und die Snapshot-Zeit der Suchergebnisse erfüllen SEO-Anforderungen

Nachteile:

Einzelner Thread, langsam Geschwindigkeit
