Thank you
First of all it may take 3-5 working days for ads to show on Google Search /content network as ads go in for manual review before they are allowed to run.
If your bid prices keep on increasing then , Google may have assigned a low Quality Score to your website. This seems to be an automated process done by an algo and is determinant of Google's definition of 'Good User Experience' your site must generate for Google surfers.
A Low QS means G has decided your site is not up to Par and you may have to pay a very high price to show on the G Network.
Alternatively you may try to improve 'user experience' by studying and applying Google webmaster guidelines to your site.
Work on getting some good pages that cover the subject matter of your Ads, relate to the keywords and provide value to your visitors.
A word of warning - once a keyword for a domain has been hit by the "quality score" effect, it can take a long time to fix it - even if you completely rewrite the target page and add masses of good content. You may need to ask G to conduct a special review of the page.
5 adverts, 300 keywords - sounds to me like you might want to write more adgroups, more targeted to specific keywords. Adwords state that they prefer an adgroup to have around about 20 keywords. This is not always viable, but maybe it is in your case. Lots of things to try.
Why not send Adwords an email asking for help.
this is just my thoughts, but as you all know, i'm new and still learning and experimenting with everything.
Thank you
Ergo, your landing pages are probably solely advertising tools for another company's products and are probably interpreted by google in this way
The consequencies of that interpretation have been heavily discuss here on www
good luck
