Welcome to the Q&A Forum

To keep your pages and avoid the duplicate content issues i would suggest expanding your product description e.g.  Dell Color Compatible 3130CN －Magenda with chip  Dell Color Compatible 3130CN －Black with chip ...those are your produce titles, which is fine, but they are also the in page product descriptions and there is only one word different. Now the reality... you have over 20K pages indexed so the above approach may not be so practical unless you have a bit of cash to throw at a mechanical turk project that gets all your product descriptions rewritten. You really ought to introduce something like Disqus that lets people comment on products which in turn would generate a load of unique content, but this would take a long time. If I was you I would consolidate products like this into a single page with a comprehensive product description and then put a canonical tag on each of the individual product pages so you can still keep them separate, but for SEO purposes you are telling the search engines to pick up one great pages and not loads of poor pages with no unique content.

As a general rule of thumb the more higher your content is placed in the page source, the more accessible it is for search engines. This ensure they correctly pull the right page info and meta data. Taking a quick glance of your source code, I definantly think your externalise all JS in a single file to remove the amount of bloated code which currently exists. Also two more things: (1) Further optimise your page. More people would search for multi color function printer than a refurbished printer. Make sure you conduct keyword research for all product pages. (2) Even though  this is not as important, none the less reduce the number of h2 & h3 heading tags you are using, particularly the links with the headings in the "supplies and accessories" section as it is not necessary. Hope this helps, Vahe

Can you please explain more? I am seo beginner, so for now I am just correcting the things that seomoz pro tells me, errors and warnings. I have reduced errors to 0, and I am trying to reduce warnings also.

2569 links is far too many, and is likely a very big problem both for your users and SEO. You have more links then the New York Times. Ask yourself this question....if you had to reduce your total number of links to less then 100, what would you do? You can likely use category pages for your products and only link to the category pages from the navigation.

anyone in here? what should I do to fix this?

I'd go for the content at the top too normally as you want your keyword rich content to be as close to the top of the page so that it is treated as a little more relevant. That said, there is quite a lot of text and in this case I can see that visitors might arrive on the page and only see the text above the fold. In which case I might look at a compromise of splitting the content with some above the items and some below. Don't just think about the SEO value, but also about how your actual human visitors are going to experience the site. I'd also surpress the text on the second+ pages on the navigation. People don't need to read it every time and there's a risk of duplicate content issues.

I agree with Robert on all points. A few other thoughts..... If your customers are "creatures of habit"... who visit once every six weeks, buy the same items and leave then I would not be changing homepage very much - at least not the parts that these people use.   I might have a few items that rotate and I would do that with server-side includes that are rewritten by a perl script. If you have lots of repeat customers who visit and buy diverse things then a homepage with more activity might make sense.  However, if most of your repeat visitors arrive once a month or even once a week then changing homepage daily is quite a lot.

It does benefit my user, so what you are saying is that I should ignore these warnings.

in case they do not all start with /category Disallow: product_compare

Hi Kami, You might want to ask this in a new post. New posts on old threads don't bump a post in the Q&A forums, so not too many people will see this post (I only knew about it as I was notified from having subscribed last year).

I assume to stop webmaster tools from crawling those pages, you've changed your robots.txt file? Our SEOmoz crawlers will obey the rules in the robots.txt file, and when your site's recrawled, those errors should drop away for the pages you've said not to crawl.

You should decide which pages you want indexed. You should ask someone who uses Magento about additional practcal tips, I haven't used it so far. As i see parameters appear when you filter results according to price or some other technical parameter. The problem is not just the parameter in the url, but also that the title of the page reamins the same although both content and url is changed.This way you are generating duplicate titles as well. One solution might be to place canonical link elements when results are filtered as those are not specific to your search term. The link should tell google that the canonical page for filtered results is the category page itself. So for https://www.theprinterdepo.com/printer-bundles/refurbished-laser-printer-bundles.html?price=3%2C100 the canonical page would be https://www.theprinterdepo.com/printer-bundles/refurbished-laser-printer-bundles.html. Be aware with simply removing attributes because if those pages are already displayed in SERPs than you might lose traffic. Canonical would be the best solution I think.

Same question... what is the solution?

If you download the crawl report to Excel, one of the fields is titled "referrer". That field shows the page with the broken link.
