KWAlert.net has been updated. Let me present the features of the new version (still beta):
A) You can now choose between three types of scrape
1) Fast Scrape: It's works like the previous version and will normally find around 350 related keywords.
2) Deep Scrape: Provides 1000-1500 related keywords.
3) Trend Scrape: Scrapes Google Trends for related keywords that are currently on the rise in terms of search volume. It also provides some parameters for each result:
Last Spike = Start date of the latest growth in search volume
Growth = Average percentage of the volume change
Period = Length of the volume change in days
B) Different alphabets can be used for scraping. When you select a language that makes use of a non latin alphabet, the system will append the appropriate letters to the term you enter. (Currently, only Russian and Latin alphabets are supported. More will follow soon...)
C) Same queries are merged together. If your query matches an older query (by another user), you will see all the results contained in our database.
You can try the new beta version at dev[dot]kwalert[dot]net
Have fun!
