Onsite, consider linking to your other pages by linking to pages within main content text. I usually only do this when it is relevant – often, I’ll link to relevant pages when the keyword is in the title elements of both pages. I don’t go in for auto-generating links at all. Google has penalised sites for using particular auto link plugins, for instance, so I avoid them.
For traditional SEO, this has meant some loss of key real estate. For SERP results pages that once had 10 positions, it's not uncommon now to see seven organic search results below a Featured Snippet or Quick Answer box. Rather than relying on PageRank algorithm for a specific keyword, Google search queries rely increasingly on ML algorithms and the Google Knowledge Graph to trigger a Quick Answer or pull a description into a snippet atop the SERP.
Taboola (like many websites) would benefit from iterative SEO, meaning its team should make distinct revisions to the SEO page titles, content headers, and other text to see whether rankings improve without hurting their top positions. But they shouldn’t make too many changes at one time or they won’t know what worked and could disrupt rankings. They could monitor rankings after testing keyword-placement scenarios. (Most website pages are indexed within days or a couple weeks.)
Influencer marketing: Important nodes are identified within related communities, known as influencers. This is becoming an important concept in digital targeting. It is possible to reach influencers via paid advertising, such as Facebook Advertising or Google Adwords campaigns, or through sophisticated sCRM (social customer relationship management) software, such as SAP C4C, Microsoft Dynamics, Sage CRM and Salesforce CRM. Many universities now focus, at Masters level, on engagement strategies for influencers.
On the voice and natural language side, it's all about FAQs (frequently asked questions). Virtual assistants and smart home devices have made voice recognition and natural language processing (NLP) not only desirable but an expected search vector. To predict how to surface a business's results in a voice search, SEO professionals now need to concentrate on ranking for the common NL queries around target keywords. Google's Quick Answers exist to give its traditional text-based search results an easy NL component to pull from when Google Assistant is answering questions.
The emphasis on tools, meaning plural, is important because there's no one magical way to plop your website atop every single search results page, at least not organically, though there are best practices to do so. If you want to buy a paid search ad spot, then Google AdWords will happily take your money. This will certainly put your website at the top of Google's search results but always with an indicator that yours is a paid position. To win the more valuable and customer-trusted organic search spots (meaning those spots that start below all of those marked with an "Ad" icon), you must have a balanced and comprehensive SEO strategy in place.
