It’s not as simple as just throwing your website links onto directories etc. in the hope that you can build up enough backlinks to drive your site up google. If you want to get real backlinks to your website you need to engage with your relevant audience. For example if you are a film maker then you can go to the “relevant” websites and engage with that audience. Try writing good / relevant content relating to what you do. It’s all about engaging your audience and bringing them to your site in that way. Social media, blogs and your own blog is a great way of engaging people and bringing them to your site.
If you just randomly link from unrelated websites google will penalize you for it. Keep it relevant! That’s how it is today. for a good start follow TechnoBear’s advice and start looking at advice from MAtt Cutts.
I dont actually find any new link building tactics, never forget the evergreen content based link building they are always the rockstar, infographics are even getting stronger, videos, slide share could also help
Relevancy of link building is important, you need to submit your websites in the relevant business websites. This will create traffic as well as the good backlink to boost your ranking.
Seriously concentrating on my blog has been a game changer for me. But almost more importantly, I have found the hard sell no longer working in blogs. Helping, not selling, has been key to what works for me. When I hard sell, interest and traffic goes down, and thereby my bottom line. On the other hand, when my blogs are 97% helping and 3% selling (in this example, simply mentioning the name of my business and do contact me if interested).
This follows through in all the ways of promoting your blog. When I do so with selling in mind, interest goes down. But finding out what questions people really have within my field, and addressing them, has worked wonders.
Think of it this way with “selling widgets” as an example: 1) Posting on Facebook that people should read your blog because your widget is the best; or 2) Posting on Facebook that you’ve just blogged about a great way to stop annoying clicks when using your widget - if annoying widget clicks are driving you crazy, take a look at our blog.
I believe you’ll get much more interest and traffic from example #2, which helps, rather than everyone running to your blog because they want to buy another widget.
@Ra_Ju has specifically asked for techniques which are “Google safe”, so backlinko would need to be viewed with caution, as not all the techniques listed there fall into this category.
