Very often, display advertising stands at the beginning of the customer’s journey, and with this type of ad you can target a much broader audience during the inspiration/awareness phase and create attention for your brand thanks to targeted placement. It is also one of the cheapest ways to increase brand awareness. Just going off of the Google Display Network alone (which SEMrush provides data on), it reaches approximately 92 percent of all internet user and 65 percent of those users are reached daily.
11th point to me would be too look at your social media properties, work out how you can use them to assist your SEO strategy. I mean working on competitions via social channels to drive SEO benefit to your main site is great, working on re-doing your YouTube videos to assist the main site and also working on your content sharing strategy via these social sites back to the main site.
Google is currently been inundated with reconsideration requests from webmasters all over the world. On public holidays the Search Quality teams do not look at reconsideration requests. See below analysis. From my experience it can take anywhere from 15-30+ days for Google to respond to reconsideration requests; during peak periods it can even take longer.
Another point which you did mention (between the lines: "and updating your backlinks to point to HTTPS URLs") but I actually didn't realize enough is that updating backlinks when your site switches from http to https is very important. Redirecting all http traffic to the https version of your site from the server (301) is necessary, but doesn't solve losing referral data. Only updating backlinks, especially those on httpS-sites, does. I'd like to emphasize that!
The term “organic” refers to something having the characteristics of an organism. Although black hat SEO methods may boost a website’s search engine page rank in the short term, these methods could also get the site banned from the search engines altogether. However, it is more likely that readers will recognize the low quality of sites employing black hat SEO at the expense of the reader experience, which will reduce the site’s traffic and page rank over time.
The term “organic traffic” is used for referring to the visitors that land on your website as a result of unpaid (“organic”) search results. Organic traffic is the opposite of paid traffic, which defines the visits generated by paid ads. Visitors who are considered organic find your website after using a search engine like Google or Bing, so they are not “referred” by any other website.
