Should you link to other sites?
-
Yes, if it "makes sense" to the visitor and is somewhat related
-
No, linking out leaks PageRank and can cause your rankings to decrease
-
Maybe, if they're at least a PageRank 4
-
Yes, linking out to as many places as possible will help your rankings
Linking to other quality, relevant sites is beneficial for SEO and user experience. Outbound links to authoritative sources can enhance credibility and provide value to visitors. Option B is outdated - PageRank "leakage" is a myth; linking out doesn't harm your rankings. Option C is too rigid, focusing on PageRank metrics rather than relevance. Option D is wrong because indiscriminate linking to many sites looks spammy. Option A correctly states you should link when it provides genuine user value.
