Some agencies still give attention to building links, but I’m unsure I’d call which a strategy. The great link-focused agencies normally have a bag of tactics/tricks they love. These tactics are proprietary, which implies it’s difficult to get them spelled out on Quora.
Having said that, there are a few great tactics shared on regularly, and you’ll find a great deal of interesting stuff exploring on that site also (a great deal of which happens to be free).
However, so far as a strategy, one way link building plays second fiddle. Links aren’t the be-all-end-most of online marketing – you need them to have success, but you also require a great social websites presence, good content, website that converts, etc.
In my opinion, building links fits into a better online content and PR strategy.
At my agency, we give attention to a niche market (auto parts), which allows us to both cultivate content expertise (all my content creators are car nerds) and cultivate relationships with industry media (I’ve got a decent set of automotive journalists and bloggers I can get in touch with and expect a response). Our strategy:
Create content hopefully auto enthusiasts will like (and we of car nerds makes us somewhat successful in that)
Contact the best journalists/bloggers inside the automotive niche (whom we all know, or at a minimum know via email) and “pitch” them our content
If/when the content resonates together with the blogger/journalist, we get a mention of the client’s brand name, and usually a web link
The hyperlinks are editorial and come from the highest quality sites, and then we have nothing to fear from the efforts. It’s 100% “white hat,” that you simply can’t always say about link-building. The company name mentions put our clients looking at thousands (or tens of thousands) of automotive enthusiasts. I don’t fully realize 40dexppky the ROI on these mentions is, however it can’t be bad.
…Not forgetting, we’ve got a very nice piece of content on the client’s site that can generate search and social media traffic/interest for years to come.
Our “trick” is an industry and niche focus. It’s challenging to create content that basically “pops” if you don’t have expertise in-house, along with that it’s difficult to understand who the very best bloggers and journalists are in a niche market without doing some operate in that niche for a long time.
