Low traffic Germany AdWords Shopping campaign

Dear members,

I am the proud owner of a beer webshop in the Netherlands https://www.mooibier.nl, Germany https://www.tollesbier.de and the United Kingdom https://www.grandbeers.com

Our webshop has more then 700 differen craft beers, in which you can customize your own crate of beer.

However, to improve traffic and revenue we started to setup some Google Shopping campaigns.
In the Netherlands we already had one, but within the UK and Germany we didn't, so we created a feed for both Germany and the UK, and gave them the right google categories.

Germany:
g:google_product_category>
Nahrungsmittel, Getränke & Tabak > Getränke > Alkoholische Getränke > Bier
</g:google_product_category>

United Kingdom: (currency converter)
<g:google_product_category>
Food, Beverages & Tobacco > Beverages > Alcoholic Beverages > Beer
</g:google_product_category>

We have no errors and some warnings in the merchant center but the shop's are receiving traffic with shopping, and after several checks of myself and the helpdesk of Google there is no major issue.

However, even if all the campaigns have the samen settings, the google shopping campaign in Germany received only a several clicks a day. In March this was 1 ~ 2 clicks a day, with an average cpc of about EUR. 0,02.

Shopping Germany
Average clicks a day 1 ~ 2
Average impressions a day 50 ~ 200
Daily Budget is EUR. 30
CPC benchmark EUR. 0,36
CPC bid EUR. 0,46


First impression, higher the bid, so I did.
After doing this the cpc was between EUR. 0,01 and EUR. 0,54 but the impressions and click still didn't increase, and the the lost impression share was still the same (around 46%). This means that following the metricses I already reach about 50% of the German population who is searching for my products. Wich is weird if you see the data of the Netherlands and the United Kindom.

the Netherlands daily budget of EUR. 30
~ 4.000 impressions a day
~ 120 clicks a day
~ EUR. 0,16 a day
~ Lost impression share 70%

the United Kingdom daily budget of EUR. 30
~ 1.500 impressions a day
~ 50 clicks a day
~ EUR. 0,13 a day
~ Lost impression share 70%


If we analyze this data, it means that we already have a coverage of ~50% of the German market with an average of ~100 impressions a day, which is realy low for a country of a population of ~82.000.000 people. Ofcourse I looked in Google.de or my shopping ads apear, and it did on exact matches like "Name beer + name webshop" or occasionaly on "Name beer".

After using the keywords tool, I discovered soms spikes in search volumes on terms like "craft beer" etc. So I had added this kind of keywords in the title description feed.

Didn't had any effect, and my ads didn't appear on this kind of search terms (well my competitors did). After calling AdWords the helpdesk in the Netherlands, Ireland, Germany and even in the United States, I received answers like:
- higher your bid (which i did and didn't effect anything in traffic)
- change campaign priority to high (which also didn't do anything)
- change bidding strategy to enchanced CPC (no effect at all)

After phone call #11 with Google AdWords (Germany), I received the tip to increase my Product descriptions. So I made a script that every descriptions included the product description + category descriptions which the product fell under.

Following effect:
~ 200 impressions a day
~ 4 clicks a day
~ 50% lost impression share

Because of the large descriptions my products include keywords like:
- Craft Beer - 18.000 search volume
- Speziell bier - 5.000 search volume
- Englisches bier - 4.000 search volumes
- etc. and etc.

Still my ads don't appear on keywords like this while my competitors do in Germany. And I still have a traffic of ~4 clicks a day.

In the AdWords account of the Netherlands and the United Kingdom most traffic comes from shopping while in Germany the traffic only comes from search campaigns. This campaigns bid on keywords which we have also in the description. Impressions and clicks in the campaigns are limitless while the shopping campaign isn't receiving any traffic at all.

Help me please!
