Welcome to the Q&A Forum

Hi manynau I would just do it anyway for best practice but it's not necessary as you have already said to ignore this URL and use the canonical. Sometimes even though a page is canonicalised to another it can occasionally pop up in Google and when it does you do not want it to be blank. Regards Nigel

Hi Marynau Look on the right side of teh Moz bar and they give a rating out of 17. I'd say anything over 6/7 would be considered bad. Having said that I rely on SEMrush to tell me if it's toxic or not. Best Regards Nigel

Hi Marynau It's considered bad practice to link to other sites through footers. It results in 100s and often 1000s of links coming to you from one site which could be considered spammy. You probably won't get a manual penalty but there may be an algorithmic one if it happens too frequently from a number of different sites. Check the spam score of the site linking to you - use the MOZ bar - if they are a sponsor then they are likely to be OK. Then politely ask them to link to you once from an 'Our Sponsors' page or just one link from the home page (as it's likely to have a higher PA - page authority) I hope that helps, Regards Nigel
