Welcome to the Q&A Forum

I have an ecommerce website where some pages link to a product page with a different URL. EXAMPLE: 1: /category/product1.html (not indexed by Google) with canonical pointing to product1.html Other page link to the product like below. 2: product1.html (indexed by Google) Now the question is, does 1: pass any link juice to product1.html or not? Is it worth to change everything and link only to one URL? My site is running on Magento!

I have a huge blog which is connected to a company website. This blog is full with dead links and spam comments. Is it worth to clean up? The website itself ranks very well in search engines. I'm amazed with all de spam that it still ranks. Do you think by removing all de dead links and spam the site will improve ranking in search results?

I'm working on a page for couple of months now and try to rank for very competitive keyword. I have reached  position 12 and it's 97% optimized, the sites keeps going up and down between position 10 & 13. I already changed content a couple of times and already created a few links with the targeted anchor tags. However I'm scared if I create more links it will be penalized. What do you suggest? Should I create more links with the targeted anchor tags or should combine the keyword in anchor tags with other words? Loading time, title, descriptions, content everything perfect optimized.
