why all of my adword scores are 1/10?

Okay first thing is first

Just because you change your landing page doesn't mean your quality score changes right away. There is a little something called a landing page bot that is dedicated to crawling AdWords landing pages. You need to wait until this bot comes along to crawl your page before you will see any change in your adwords quality score. Also even when the bot has visited the pge doesnt mean you can expect an instant quality score change. Sometimes it takes a few hours, sometimes a few days. This is MOST LIKELY why you haven't seen a change (the other option being that your changes had no impact on qs). What exact changes did you make?

Your second question is your quality score start at 5/10 and then drops back down to 1/10 well...when you make changes to you campaign and launch it again google will assign you a quality score based on past performance of your campaign among other things, once the campaign actually starts to run it asses the 'real' quality score and drops it back down to the 1/10.

Don't keep changing your site, make a change and then test it by waiting a few days. Make sure your using analytics and try adding google webmaster tools or whatever its called to see when the bots come along.

Well, I did say it's because of your affiliate links on your page. Here's Google's part of their TOS that deals with this:

Certain kinds of websites are not allowed per our policies because the user experience is of low quality or we consistently receive negative feedback from our users about these kinds of pages. These sites include:

* Data collection sites that offer the false promise of free items, etc., in order to collect private information.
* Arbitrage sites that are designed for the purpose of showing ads
* Affiliates who provide limited value by being a bridge page with the intent of solely driving traffic to another site or who are framing an affiliate site
* Malware sites that knowingly or unknowingly install software on a visitor's computer

The third item is the one you, and everyone else, should pay attention to.

No amount of change on your page will change that, unless you remove your affiliate links. You can delete and recreate your campaigns, it won't change a thing. You will get an initial QS, the system is going to evaluate the campaign, see that you have affiliate links and change your QS down to one which is effectively an off switch.

The bot that checks your page I've heard comes around about every nine days. You have to wait for it to visit you before your landing page portion of the QS is re-evaluated. Of course, if you create a new campaign, group, ad and I believe adding a keyword, the bot visits ASAP.

I very much doubt google is punishing you, it may be one or some of those links you have now listed may have fallen into the G spotlight, and as such may be a reason for the now low score.

Or the layout itself is still set up wrong and may need more content and or keyword enriched information, I will almost say 100% it not because of the use of a affiliate link in its raw form

Some links affiliate or not leading to sites as deemed not suitable would draw a red flag if you tried to promote tham

From memory, the page was heavy in survey type offers with very little content, and if it were me looking at fixing that, i would break it down into bite size chunks to find the problem, by listing one site / product plus good content on the page, if that held then you could add another product / content or page if need be.

This way you should be able to identify any links that may be causing you a problem.

as lucid mentions there are some sites that fall under the spotlight more so and some survey sights may be causing this problem

have you tried to run adwords on other pages not related to survey sites as that would / may help with a better picture

if you do get a poor qs you must delete that keyword straight away, do not leave it sit as it will not matter at that point you will not be ale to fix it.

Its Google and you need to work for your ADS + LP + KEYWORDS than only you will increase your Score.
