We’ve previously published articles on how to optimize the links in your blog or Web site to increase their value to search engines. A knowledge of how to best structure your links can help your site and other useful sites be ranked higher by search engines.
I just read an article that is a useful refresher on what kind of links are the best: “All Links are Not Created Equal: 10 Illustrations on Search Engines’ Valuation of Links.” Below are the 10 points from the article. If this interests you, I recommend you read the whole article. It’s easy reading with good examples.
- Links Higher Up in HTML Code Cast More Powerful Votes
- External Links are More Influential than Internal Links
- Links from Unique Domains Matters More than Links from Previously Linking Sites
- Links from Sites Closer to a Trusted Seed Set Pass More Value
- Links from “Inside” Unique Content Pass More Value than Those from Footers/Sidebar/Navigation
- Keywords in HTML Text Pass More Value than those in Alt Attributes of Linked Images
- Links from More Important, Popular, Trusted Sites Pass More Value (even from less important pages)
- Links Contained Within NoScript Tags Pass Lower (and Possibly No) Value
- A Burst of New Links May Enable a Document to Overcome “Stronger” Competition Temporarily (or in Perpetuity)
- Pages that Link to WebSpam May Devalue the Other Links they Host
