Adsense referrer spam?

I made a whopping 0,12€ with ads on this blog over the last 30 days (and just disabled them entirely, don’t want to get corrupted by all that money). However, what really caught my attention in the report was a domain that doesn’t belong to me (or my company):

Adsense Referrer Spam

So, apparently t**** used my Adsense code on their site, resulting in a single ad impression (and nobody clicked on it, otherwise, my ad revenue would have been at least three two times bigger). How and why did this happen?

The innocent explanation is that their “Web Back Machine” (which sounds suspiciously similar to the non-profit Wayback Machine) archived one of my pages, including the Adsense ads. That’s possible, but what is more likely it that this is Adsense referrer spam, meant to get me to visit their website. I’ve got to admit that it worked, so now I have to write this blog post to justify my actions to myself, see, it was all in the name of research.

For further information on Adsense referrer spam, let me refer you to this comprehensive, well-written article.

Create GS1 DataMatrix barcodes with Brother P-touch Editor

Create GS1 compatible DataMatrix barcodes in P-touch Editor by following these steps:

Insert the DataMatrix barcode

In P-Touch Editor, select Insert > Bar Code from the menu. Switch to the Protocol tab and select the DataMatrix protocol:

DataMatrix Protocol

Add the Function 1 Symbolic Character (FNC1)

This special character is used to differentiate GS1 DataMatrix from other Data Matrix barcodes. Go to the Setup tab and check the Specify Industrial Protocol (FNC1) box:


Add the GS1 element strings

You must follow the GS1 rules when encoding data in a GS1 DataMatrix. I highly recommend that you review Chapter 2 (Encoding data) in the GS1 DataMatrix Guideline (PDF). P-touch editor won’t prevent you from making any mistakes!

As an example, I’m going to recreate the GS1 DataMatrix barcode found in TL A-0032 Part 1, Edition 7 (page 12).

It contains both a GTIN-13 (4012345000016) and a serial number (ABC17829). The corresponding GS1 DataMatrix Application Identifiers are 01 (GTIN-13) and 21 (serial no.). The GTIN-13 has to be padded with a leading 0 to match the expected length of 14 characters. Therefore, the concatenated string is  010401234500001621ABC17829:

GS1 DataMatrix data

The resulting barcode matches the example, though it seems that P-touch Editor cannot add the Human readable Interpretation (HRI):

GS1 DataMatrix comparison

You could, of course, add the HRI using the text tool.
