Welcome to the Q&A Forum

Here's my opinion; Google's spiders will have more difficulty interpreting and following affiliate links using the onclick="window.open... method, but that doesn't mean that they can't. To my knowledge they can follow these links and even pass juice between them. Although I'm not sure that it would affect your rankings and so whether changing the links would do anything; after all, they're outbound links. If you were to nofollow them, then you would still loose the same amount of link juice, it just wouldn't flow to the trading sites. On a separate note, as you know; Google's problem seems to be that you're acting as a 'middle man' from the sites who are actually selling the treadmills. From the odd story I've heard, unless your site is bringing something 'unique' to the equation then they don't like to have it promoted in their advertising space, they prefer to have the actual seller paying for the advertising. One way I've heard to get around this is to have a PPC specific landing page that concentrates purely on the review side of things, however I'm not sure whether your site would be flagged by them now or not.

Depends on your use case but this is a good resource: http://www.whichmvt.com/ Personally I really like VWO: http://visualwebsiteoptimizer.com/ I like the way you don't need heavy code changes to run tests.

I always though guest replies would be ignored by Google, is this the case? Guest replies are definitely not ignored by Google. Sometimes you can perform a search for a term and the result will lead you to an article where the search term is only located in the user generated comment section of the page. Our competitor sells clothing but has a reply on a CSS site? Would this be worth doing like this or is it a waste of time? I would suggest working to obtain as broad of a link profile as possible. I like being linked to from credible off-topic sites such as a CSS or graphic design sites for two reasons. First, if it is a follow'd link it offers at least some value and serves to broaden the site's link profile. Additionally if my client's site looks so good it is being mentioned on web design sites, I know the overall design is good. Of course there is the corner case where you are being called out for bad design, but I'll let that topic go In short, receiving mentions or links from design and other off topic sites is nice, but should not be a focus for your link building efforts unless your site is related to those topics.

If what you are asking is how to optimize the image so it does well in google image search, then best way is to put a caption under the image you want to appear in the image search Google pays attention to about the next 70 characters following the image on the html/php page. so if you want to rank well for brown bowling shoes in image search simply put brown bowling shoes on the html/php page right after the image, also use brown bowling shoes it the alt attribute of the image , this will especially help if the image is clickable. It sort of counts like anchor text of the image.

why not do a search on facebook and other web 2.0 media websites find pages from other doctor's offices or even similiar "professional" professions like laywers ,accountants etc. and show him those pages as examples. These pages do not have to be local doctors, lawyers. They can be from anywhere - even thousands of miles away. Show him what others are doing.

if you change site servers it will most likely not stop the traffic because the adware is sending you traffic based upon the domain name of the site, not the ip, if you change site servers the dns will simply resolve the domain name to the new ip. Your rankings will not change in serps if you change the webserver. It does not matter.

That's a bit of a pain. If anything tell them to set up a custom informative 404 error page that will at least direct them somewhere else and not bail from the site.

if it is a dofollow link and it is free  then go ahead and get it. It does help a bit, not much. If it is a nofollow then it does not help with pagerank but the anchor text of the link still counts. So if you want to rank for idaho potatos, even a nofollow link with idaho potatos in it counts a bit. Dofollow counts for pagerank as well.

So do you say if I got penalty by Google then they must mail me about why I got penalty. If none mail comes then it's not a penalty.

We use caching and have seen no ill effects. I seriously doubt spidering robots will be hitting your site's pages every 15 minutes. One thing you might want to look into is the "If Modified Since" header, which could help notify Google that your content has changed http://www.seomoz.org/blog/whiteboard-interview-googles-matt-cutts-on-redirects-trust-more

For smaller markets especially, this can be infuriating. I would recommend looking at the recent changes and trajectories in markets like Italy, Spain and Portugal that have had these problems but where Google is gradually focussing effort. I think a lot depends on your timescales, but if you are building a business that you want to last, you should be using sustainable tactics IMO.

It's not as bad as it sounds

Great. Thanks for your prompt reply and I suppose to integrate with my problems.

No probs glad to help! Best of luck!
