Welcome to the Q&A Forum

Hi Dennis! What do you mean by that website? That URL is from a price comparison website.

For metas: I am just recently added meta-description [Category-name. Product-description].

Categories: I am recently started to add nice descriptions to categories

Inernal linking: they were product tags ([product_name], [model_name], [manufacturer_name], [categories_names] ->with URL) on the product page, but I removed.

So linkbuilding is still necessary?

I have some products, which are not shown in Google SERP.  Here is a link for basic SERP report, here is another for the product on my site. MOZ's Grade Tool: A

Why isn't my site showing up on Google results pages for this keyword?

Thank you!
