Different link types do different jobs. A healthy backlink profile has a mix, and that link diversity is a big part of what makes it look natural to search engines.
Guest Posts
Guest posts are still the backbone of most campaigns. You write (or commission) an article for a site in your space, and your link goes inside it.
Done well, guest blogging gets you a contextual link on a relevant page and some exposure to a wider audience. Done badly, it's 500 words nobody reads on a blog that publishes forty posts a day. The difference comes down almost entirely to which bloggers and publishers you pick.
A good guest post reads like something the site would have run anyway: unique content, useful to its readers, written by someone who knows the subject. Editors at reputable blogs won't accept less, and the bloggers who'll accept anything usually aren't worth the money.
Niche Edits and Link Insertions
Niche edits, or link insertions, put your link into an existing article. The page is already indexed and often already ranking, so the link tends to get picked up quicker than one on new pages.
What we like most is that there's no guesswork. You can see the ranking article, its traffic and how many other links it carries before you pay. With a guest post, you're trusting new content you haven't read yet.
Honestly, a well-chosen edit can outperform guest posts on the same blog, simply because that page has had years to build its own authority.
Digital PR Links
Digital PR is about getting coverage on news sites and big publications, usually off the back of a strong story, some original research or an expert comment. Digital PR links tend to come from high authority domains and can do wonders for a brand's visibility.
They're also pricey and hit-and-miss. We'd only tell companies to go for digital PR once they've already got steady link building ticking along underneath it.
If you do have a go, find a genuinely new angle first. Journalists bin press releases that only exist to get links.
Roundup Posts and Expert Quotes
Roundup posts gather advice from a handful of professionals on one topic. If you know your field, getting featured isn't hard, and the links usually come from blogs in your sector.
Some roundups are thin and only there for links. Before you send anything, check whether the post gets real traffic and whether the other contributors are people you've heard of.
Niche Directories and Business Listings
Directories have a bad name, and mostly they earned it. The general web directories of 2010 are worthless now. Some are actively harmful.
Industry directories are a different story. Think trade bodies, associations, local directories and the handful of curated listings that people in your sector actually use. For local SEO and service businesses especially, they're worth the effort. Keep your business profile the same across all of those directories and citations (same name, same address, same categories) and Google has a much easier time trusting who you are.
Our test for any directory is simple. Does it have real visitors, and would you be happy for a customer to find you there? If so, submit. If it'll take anyone with a URL and a credit card, walk away. Most free directories fall into that second group.
