Welcome to the Q&A Forum

in this case simply canonical tag the less optimized pages to the main page you want to represent your site

this would be the representative URL most likely:

mysite.com/product.html

I would lose the .html extension too.

good lord.

please mark sandip's and/or matts response as a good answer or thumbs up if they helped you

yahoo can detect spam and remove your posts and block your account. Sometimes they stick if you only do a few but any significant link building will result in Yahoo marking you as a spammer, and kind of rightfully so.

post the URL and we'll take a look at it.

Breadcrumbs add great value to the pages and helps pass PR around the site. However, since you are going around the CMS, you better keep the links under tight control to make sure the breadcrumbs don't eventually lead to 404 pages. Also, I strongly suggest to use the breadcrumb microformat for an enhanced search display in Google search results.

you were penalized, so now your main pages don't rank for your main keywords, only your inner pages are ranking for keywords which aren't your main keywords. If you're penalized you won't rank for those anymore until you fix the issue so you're probably seeing the others you are ranking for surface.

Did you put the links on those sites yourself and now you want them removed? He doesn't have to legally remove them, and remember u catch more flies with sugar than vinegar.

Are the pages your links on even indexed, if not then it's not a problem.

$20 per link is a scam. I would offer to paypal him $30 to remove them all.

Nofollowing allows you to safely link to another site, but if both sites are targeting the same keyword universe and you are exposing ownership by interlinking, same phone number, same address, same server, similar url and site structure, same database, etc then you are going against Google's guidelines. Interlinking just puts you at more of a risk if that is the case.

it doesn't really matter. just don't go multiple levels deep and don't repeat keywords in the url.

Usually an on page audit lists all of the problems and possible reasons why they are happening, not in depth info on how to fix all the issues. That is usually the next phase, "do you want me to work on the site or do you want your dev team to track down the cause of the issues and fix them"

It also depends what type of contract you have with him of course.

I've paid many people via paypal to remove links because it works. i don't care if it makes them think about charging other people in the future i want to get my links removed and will do it in the most efficient manner possible. I paypal them after i have confirmed the links have been removed successfully.

people are busy and if you offer someone some compensation for their coding time you get a much better response rate. especially since they probably are getting a lot of requests now.

homepage is indexed under both www and www versions

"underfloor heating" too many times on the homepage, bolded, hyperlinked, etc. it's overdone

keyword stuffing

<meta name="<a class="attribute-value">description</a>" content="<a class="attribute-value">Underfloor Heating provided by underfloor heating company UFH1\.  
Suppliers and installers of underfloor heating kits based in Doncaster. Our underfloor heating systems are installed throughout the UK.</a>" /> <meta name="<a class="attribute-value">keywords</a>"
 content="<a class="attribute-value">underfloor heating, underfloor heating kits, under floor heating, underfloor heating systems, underfloor heating, UK</a>" /> 

I prefer www but either way is not a problem as long as you are 301 redirecting the one to the other and your internal linking does it the same way.

Also external links pointing to you should be coded correctly too, since most people use www that would be another good reason to go with www.

This looks fine, not to flimsy. Tabs are all on the same URL so no problems there unless that content in the tab is repeated on hundreds of similar product pages. If the content is unique to each product then you're good. I see enough info on this page.

good looking site.

I think a personal website is better for SEO than a shared platform such as blogger (which google owns) and wordpress.com.

But if the blog is established, gets good readership and traffic as you said then it's mostly a traffic play anyway, and I would go for it as long as it's a quality site and doesn't allow spammy articles or spam comment posts.

totally doable, 1-2 keywords per page, so a 50-100 page site can accomplish this. no problem at all

if the linking is exactly the same it should have no effect on SEO, but could have a neg or positive effect on bounce rate and other user experience stats.

you could always safely a/b test it

You need to do keyword research for the long tail unless the product is obvious like

Adidas Crosstrainers Velcro in Blue Mens Sneaker

Adidas Crosstrainers Laces in Yellow Womens Sneaker

If the pages get indexed the link will be seen and counted (although probably discounted) duplicate content only means Google will filter the search results but you're not doing it for traffic anyway. The only thing you are doing is spamming though, at least if you create unique articles it looks less spammy.

main keyword anchor text is sometimes not exploited with a negative SEO attack, it's just a massive amount of links from bad sites which harm the site in general. this can easily be detected with link detox for example or you can do a link:(space)www.yourdomain.com search in Google.
