That said, ground-up marketing works because it’s work. There’s no substitute for careful attention to your website’s content and careful curation of your business’s social media presence. Paid ads can be an effective tool within a high-budget marketing strategy, but if the consumer arrives at your website and doesn’t find what they’re looking for, how is that investment working for you? It’s not. If a sponsored tweet draws them in but a discrepancy in expectation chases them away, what’s the benefit there? It’s absent. Organic marketing is a long process, but ultimately it will yield more authentic customer engagement and more accurate SEO.
PPC (paid search marketing): PPC (pay per click) advertising involves paying to have search engines display your website offer in or alongside search results. For example, Google's Adwords program will display your ad at the top or right side of the search results page (placement depends on many factors including keywords and quality of ad). Google will also feed your ads to websites running its Adsense program. There are other types of PPC marketing, such as Facebook Ads. In PPC advertising, you pay each time someone clicks on your offer. Paid search differs from organize search in that you're paying to have your website or offer displayed higher in search results.
People find their way to your website in many different ways. If someone is already familiar with your business and knows where to find your website, they might just navigate straight to your website by typing in your domain. If someone sees a link to a blog you wrote in their Facebook newsfeed, they might click the link and come to your website that way.
When used correctly, PPC can be highly efficient. Since you only pay when people click and you can target people looking for specific terms, it can be an excellent means of bringing people to your site. Even more importantly, PPC ads have been shown in some studies to even boost visibility and clicks, particularly if your organic result starts to slip further down the page. This can help improve brand reach and maintain a strong reputation.
Regarding Link Detox, links it diagnoses as Toxic are generally fine as they're either not indexed by Google or have malware/viruses/etc., but I recommend a manual review of any diagnosed as Suspicious. I used it recently to get started cleaning up our backlinks and some legit sites and blogs were under Suspicious simply because they didn't have many links pointing to them.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
