One of the reasons for a traffic drop can also be due to your site losing links. You may be seeing a direct loss of that referral traffic, but there could also be indirect effects. When your site loses inbound links, it tells Google that your site isn't as authoritative anymore, which leads to lower search rankings that in turn lead to traffic drops (because fewer people are finding your site if it's not ranked as highly and more).
Optimise for your personas, not search engines. First and foremost, write your buyer personas so you know to whom you’re addressing your content. By creating quality educational content that resonates with you>r ideal buyers, you’ll naturally improve your SEO. This means tapping into the main issues of your personas and the keywords they use in search queries. Optimising for search engines alone is useless; all you’ll have is keyword-riddled nonsense.
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.
Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic. The only channel that performs better in some capacities is paid search ads, but that is only for conversions, not overall traffic delivery (Paid Search only accounted for 10 percent of overall total traffic).
