Welcome to the Q&A Forum

Hey Dieter, I might have considered a more dynamic/interactive solution for showing multiple variations/colors of the same product (gallery/Javascript, etc.). My concern would be as follows: Each time you ask a user to refresh or visit a new page in a purchase funnel, you're increasing the likelihood of a lost opportunity. If a single-page option is not possible, you are right to look at a noindex or canonical solution. Personally, I'd recommend the canonical solution. This way, any existing link juice (if any) is being attributed from extraneous to the primary product URL. Best of luck to you. -Brian

Most likely, one of two things happened. A) Either your site got hit by the algorithm and lost rankings..... B) Or..... your competitor was favored by the algorithm, moved up, and you lost rankings. There are other possibilities, unrelated to the Google update, but checking if one of these, and which one of these, hit you is important to understand your next step.  If you have a position tracking project running on SEMrush you can add competitors to the project and see who moved up and when. Since Google has not disclosed what this update was based upon, it is hard to know what can be done.  It might be based upon how links are valued, how content is valued, user behavior, or something else, or a big mix of things.

Hi Dieter, As a companion to the great answer from the RayFlexGroup, I have a few resources for you: Could Google Shopping Feeds Be a Thing of the Past? The post highlights some of the elements at work behind the scenes to render such results. It also shares some tips brands can use to increase the likelihood that their products show up similarly. Another great resource: 5 Essential E-Commerce Rich Snippets for Your Store There certainly is a schema markup for products. Let us hear from you once you give it a try RS

surf easy worked, thanks

Thanks for your help. We reduced our markup considerably down to the review markup as you suggested.

i added it to the robots.txt, thanks for the tip, it was about 2 weeks ago

Not entirely sure what you mean, but from what I understand, you're asking if you have Image A on Product page A (this product page is already indexed) Image B on Product page B (this product page is not indexed) If so, then sure you can put Image B in your sitemap. I would be hesitant doing it if you do not want your Product page B to be indexed, though... Hope this helps

Whenever you have products that are similar (but only different in color variations or size variations), you should use the canonical tag to specify this. Keep these URLs indexed, but generally speaking the canonical tag is there to help in these situations. There are literally thousands (or hundreds of thousands?) of sites using the canonical tag successfully.

Just because you had your manual penalty lifted, doesn't mean the algo penalty (mainly penguin) was lifted as well. Be sure to check up on your anchor distribution to make sure it isn't over optimized. That being said, we had a site in a similar scenario and ended up switching to another domain after a lack of results for a while. Depending on the extent of the negative SEO, it might be the easiest solution.

Hi, As far as I know Google won't be treat this as hidden text, you are using it for better user experience. You have already mentioned the price very clearly beneath Reviews. Thanks

thanks we will test getting rid of all the utf 8 characters in the meta infos
