In SEO outbound links and backlinks are different. For SEO, two kinds of links are important, inbound and outbound links. Outbound links consists of links from your site leading to another one, and inbound links, also known as backlinks, are links from external sites leading to your site. For instance, if a .net links to yourdommain.com, that particular link from a .net is an inbound link for yourdomain.com.
Creating outbound links on your site, or "linking out" , means creating links to other websites on your website. Linking out happens naturally, and for most webmasters, it's not something you have to worry about. Nonetheless, in case you're interested about an otherwise simple topic that's fundamental to the web, here's the good, the bad, and answers to more advanced questions . First, let's start with the good...
The bad: Unmonitored (especially user-generated) links and undisclosed paid advertising outbound links can reduce your site's credibility.
- Relevant outbound links can help your visitors.
- Provide your readers in-depth information about similar topics
- Offer readers your unique commentary on existing resources
- Thoughtful outbound links can help your credibility.
- Show that you've done your research and have expertise in the subject manner
- Make visitors want to come back for more analysis on future topics
- Build relationships with other domain experts (e.g. sending visitors can get you on the radar of other successful bloggers and begin a business relationship)
When it comes to the less-than-ideal practices of linking out, there shouldn't be too many surprises, but we'll go on record to avoid any confusion...
- Including too many links on one page confuses visitors (we usually encourage webmasters to not have much more than 100 links per page)
- Hurts your credibility—turns off savvy visitors and reduces your authority with search engines. If you accept payment for outbound links, it's best to rel="nofollow" them or otherwise ensure that they don't pass PageRank for search engines. (As a user, I prefer to see disclosure to maintain my loyalty as well.)
- Allows comment spam, which provides little benefit for users. Also, from a search engine perspective, comment spam can connect your site with bad neighborhoods instead of legitimate resources. Webmasters often add the nofollow attribute (<rel="nofollow">) to links that are user generated, such as spammable blog comments, unless the comments are responsibly reviewed and thus vouched for.
So are you confused?? No need.. Common Sense is the greatest knowledge of Humanity which we always suspect to use.. So keeping it simple..
If you're linking to content you believe your users will enjoy, then please don't worry about the site's perceived PageRank / backlinks whatsoever . As a webmaster, the things to be wary of regarding outbound links are listed above, such as losing credibility by linking to spammy sites. Otherwise, consider outbound links as a common sense way to provide more value to your users, not a complicated formula.
