SEO Friendly Widgetbox Widget and Wordpress Plugin Required

IMPORTANT: If you would like to bid, please ensure you supply details of other widgets you have developed. I require a widget (for upload to WidgetBox) that will calculate the true value of someone's scrap gold. The user will enter the weight of their items (in grams), they will state the purity (carat) of the gold and they will select their preferred currency. The widget will then calculate the true value of their gold. Prior to final coding, I would like to see a design creative for the widget. The latest gold price will be supplied via an RSS feed. The feed address will be supplied. The widget should also be supplied as a Wordpress plugin. The widget and plugin must be SEO friendly. ## Deliverables **IMPORTANT**: If you would like to bid, please ensure you supply details of other widgets you have developed.

The feed address will be supplied. The widget should also be supplied as a Wordpress plugin. **The widget and plugin must be SEO friendly.** Outbound anchor link should preferably be hard-coded to prevent removal. The outbound link should be outside any javascript / iFrames. The outbound footer anchor text should vary each time the widget is installed (3 or 4 alternatives) If either the widget or plugin contains an anchor link that could be removed by the user, some form of server-side validation should be included. If the server detects link removal, the widget should cease functioning and simply display a large outbound link. Appropriate validation should be present to ensure only numbers are entered into the weight field, plus the purity and currency options are selected. The widget will contain the following elements: Heading: Calculate the REAL value of your gold Input field: Weight (in grams) Selection box: Purity (9ct, 10ct, 14ct, 15ct, 18ct, 21ct, 22ct, 24ct) Radio buttons: Currency (Dollars, Pounds, Euros) Submit button: "Calculate" On submit, the value will be calculated.
