Some agencies still center on building links, but I’m not sure I’d call that a strategy. The excellent link-focused agencies ordinarily have a bag of tactics/tricks they love. These tactics are proprietary, which suggests it’s hard to find them spelled out on Quora.
With that said, there are a few great tactics shared on regularly, and you’ll find a lot of interesting stuff looking around on that site at the same time (lots of which happens to be free).
However, with regards to a strategy, professional link building plays second fiddle. Links aren’t the be-all-end-each one of internet marketing – you will need them to have success, however, you also need an effective social media marketing presence, good content, website that converts, etc.
In my view, building links fits into a greater online content and PR strategy.
At my agency, we center on a distinct segment (auto parts), which allows us to both cultivate content expertise (my content creators are car nerds) and cultivate relationships with industry media (I’ve got a good selection of automotive journalists and bloggers I could reach out to and expect a response). Our strategy:
Create content hopefully auto enthusiasts will relish (and we of car nerds makes us somewhat successful in that)
Contact the top journalists/bloggers within the automotive niche (whom we know, or at least know via email) and “pitch” them our content
If/when the content resonates with the blogger/journalist, we have a mention of the client’s manufacturer, and usually the link
The links are editorial and range from best quality sites, and then we have absolutely nothing to fear from the efforts. It’s 100% “white hat,” you can’t always say about backlink building. The emblem name mentions put our clients looking at thousands (or tens of thousands) of automotive enthusiasts. I don’t actually know 40dexppky the ROI on these mentions is, but it can’t be bad.
…Along with, we’ve got a very nice part of content in the client’s site that will generate search and social networking traffic/interest for years to come.
Our “trick” is an industry and niche focus. It’s tough to create content that truly “pops” whenever you don’t have knowledge of-house, along with that it’s difficult to determine who the best bloggers and journalists are in a distinct segment without having done some work in that niche for a long time.
