Welcome to the Q&A Forum

Hi Matthew

In Googles eyes these would be duplicate pages as 99% of the text on the page is almost identical.

Google takes a pretty tough line with this, so re-ordering a few words here and there wouldn't solve the issue, to solve the issue you really need to write unique content for each product.

You may want to consider including the product description in the area next to the picture as Google tends to put more significance on text which higher up the page.

Hope that helps.

If you noindex the short pages, Google will (or at least should) ignore them in search.

This is a commonly employed tactic for large E-commerce sites to their indexed product pages to allow them to concentrate their efforts on the more mainstream product lines.

What you are looking to do is reasonably common place.

Websites that contain a blogs, download sections etc are often hosted on separate webservers (and IP's), so what you are looking at doing should be fine.

You seem to have the major SEO consideration covered and that is to use subdirectories from the existing domain (www.oldsiteexample.com/marketing) that way your new part of the site will benefit from the authority/rank etc of the old site, also any authority generated by the new part of the site will be passed on in part to www.oldsiteexample.com further boosting its auth.

If however you use subdomains (marketing.oldsiteexample.com) you would pretty much be starting your seo efforts for this part of the site from scratch, furthermore very little (if any) authority generated by this part of the site would be passed back to www.oldsiteexample.com

I hope that helps

It will almost definitely solve the issue.

If it is any use to you, the approach I would typically take is to concentrate on 10 products and make the content changes to those pages.

These can be top 10 sellers, top 10 products in terms of value, 10 random products etc, re-write the descriptions for each of these and make them live.

I would then run a test crawl to ensure the pages are no longer seen as duplicates, then wait for Google to pick up the changes and see what effect it has on rankings and indexing.

Assuming this experiment is successful start working thru the rest, I find that concentrating on 10-20 products at a time works better for me as its more actionable and easier to work on a smaller product subset.

I hope thats of some use to you

The key thing here is whether the space is shown in the search results.

I think its unlikely that it would cause any SEO issues, if however the space shows in Google results there is a high chance it would affect your click thrus as extra spaces, weird characters etc in page titles tend to suggest that the site is less trustworthy (in my opinion).

So if space is visible in your page title and/or search results, get it sorted. If it is just tabs and line returns in the source code you don't need to worry about it too much.

Hope that helps.

To add to Mike's answer

2: If the page is deleted and isn't coming back you may want to 301 it to its new equivalent of possible even return a 410 a status code to tell search engines the pages has been permanently removed

For more info on Status codes see the following article

We have recently launched a new responsive website for a client and have noticed 2 "Not Found" errors within Google Search Console for /mobile and /m

Both these URLs are not linked from anywhere within the site. However Google is reporting them as being linked from the homepage.

This is not the first site we have seen in which Google has reported this error, however the other site was not a mobile friendly site.

My thoughts are to 301 them back to the Homepage. Anybody else have any thoughts on this? or have recently received the same errors?
