When you link to resources or original source, and in particular.... Well, lets just do it this way. I have two particular examples:
Say I have a website about boats and have an article about rules and fines for speed of the boat. I'd then link to the official law document from the government. Should such a link be
Because in this case, the link is not relevant to the niche at all (boats). But on the other hand, it is a trusted link and can be useful for the readers of the article.
Lets take the boat website as an example again. This time I'd have an article about gas and oil for the boat. Now I'd want to link to some websites or companies with good quality oil. It would NOT be sponsored or paid for in any way. Should the link this time be
Since in this case, the link is a great resource for users and they would be trusted companies. But again, the particular companies have nothing to do with the niche (boats, while these companies are just general gas and oil companies)
What if you have a lot of outgoing links to a lot of original sources and resources? Because if you would use
dofollow, wouldn't it come across spammy for Google (even though it would not be spammy and just legit)?
Would it be better to actually limit outgoing links and only use the best links or is it fine to just link a lot of good resources?
Hopefully I explained it properly. I'm really not sure what would be the best practise for SEO and haven't been able to find the answer on such specific questions.
