I’d add one thing to number 5: Writing good copy is crucial not just for your Title/snippet, but for your whole page, especially your landing page. You want people to stay on your page for a while and (hopefully) even navigate to other pages you have. Google looks at bounce rate and where they go after they hit your page. Learning to write good copy can not only increase conversion (if you’re selling something) but make your content more impactful and engaging. There are free books at most libraries or online to help.
Content is king. That’s the saying, right? It’s true in a way. Your website is really just a wrapper for your content. Your content tells prospects what you do, where you do it, who you have done it for, and why someone should use your business. And if you’re smart, your content should also go beyond these obvious brochure-type elements and help your prospective customers achieve their goals.
In the real world, its not so easy. For example, I have 2 niches where I’m trying to use your technique. By keywords, its Software for Moving and Free Moving Quotes. I have 2 websites that related to each of them, emoversoftware.com (emover-software.com as initial, they linked together) and RealMoving.com ( for latter keyword). So, to begin with, none of those niches has Wikipedia articles, so your first suggestion will not work. But, in general suggestions, you are advising to get backlinks (of authoritative sites of course). But check this out – my site emover-software.com has only 4(!) backlinks (https://openlinkprofiler.org/r/emover-software.com#.VXTaOs9VhBc) and, however, listed as #1 (or #2) by my keyword. (moving software, software for moving, software for moving company). RealMoving.com has more than 600 backlinks and is way back in ranks ( 170 and up) by my keyword. Even though those sites have different competition, its still makes no sense! It doesn’t seem like Google even cares about your backlinks at all! I also checked one of my competitor’s backlinks, its more than 12000, however, his rank by keyword related to moving quotes even worse than mine!.
AdWords and Facebook are further vehicles for reaching the appropriate audiences with more refined messaging. I think it's important to create personas for your current visitors and the type of visitors you want to attract. It might be valuable to create personas of those you don't want to attract, to keep in the back of your mind as your content and advertising calendar is being built following the delivery of your overall strategy.
Another way to increase traffic to your website is to get listed in free online directories and review sites. For most of these sites, your profile will have a link to your website, so actively updating these listings and getting positive reviews is likely to result in more website traffic. In addition, many directories like Yelp have strong domain authority on Google. There’s a chance that your business’s free Yelp page could rank high for relevant searches.
