BSR Chrome Plugin

This is a very simple project for someone who knows how to create Google Chrome Plugins

Purpose: A plugin to predict what the future BSR (Best Seller Rank) will be for a book.

Scope: Plugin should work when user is browsing eBay or Amazon


1) User lands on page with book 13 digit ISBN

2) Plugin Captures 13 Digit ISBN

3) Use 13 digit ISBN to look up data in an API (which I will provide to winning bidder) displays the following info in a display box at the top of the page:

a) Current BSR (BSR)

b) 30 Day Average Rank (BSR_AVG)

c) Summer Textbook Season BSR (BSR_S)

d) Winter Textbook Season BSR (BSR_W)

e) Trend (Up/Down)

(Please see attached image with example data)

To calculate Trend (which is "e" above):

IF date = Jan – June

Subtract BSR_AVG from Summer_Average_BSR

IF Negative

Trend = Up

IF Positive

Trend = Down

IF date = July – December

Subtract BSR_AVG from Winter_Average_BSR

IF Negative

Trend = Up

IF Positive

Trend = Down

Again please see attached image for example.
