Add as many email forms as you’re comfortable with on these pages (some users dislike sticky headers and pop-up forms). You should also integrate them with lead magnets that relate to the content on the page. For example, a fisherman’s About Me page could feature email opt-in forms that contain a lead magnet for a free, short ebook called “A Day in a Fisherman’s Boots” where he depicts his fishing routine from the moment he sets up his gear at home, to the actions and decisions he makes when things go awry during a trip, to when he finally reels in a catch and more.
For our client: We only used a smaller quantity of very high-quality link building each month. So, for example we only built 40 of the best links each month to supplement the work we were doing on the content marketing front. We also invested heavily into tracking competitor backlink profiles, using Majestic SEO and Open Site Explorer. We worked out how the competitor's acquired specific backlinks, then by using outreach and content creation we obtained these links.
The response rate here was huge because this is a mutually beneficial relationship. The bloggers get free products to use within their outfits (as well as more clothes for their wardrobe!) and I was able to drive traffic through to my site, get high-quality backlinks, a load of social media engagement and some high-end photography to use within my own content and on product pages.
Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above.

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.

Tools such as Google Adwords can help you find keywords related to your industry. Google Trends is also a great tool for finding related search queries that are increasing in popularity yet may be untapped by competitors. If you can get out ahead of some of these trends, you may be able to attract a great deal of traffic. But always make sure your content aligns with user intent. If you use trending keywords to attract users who aren’t actually interested in your products or services, you may get a bump in website traffic, but it won’t lead to actual conversions or improve your bottom line.
Plan your link structure. Start with the main navigation and decide how to best connect pages both physically (URL structure) and virtually (internal links) to clearly establish your content themes. Try to include at least 3-5 quality subpages under each core silo landing page. Link internally between the subpages. Link each subpage back up to the main silo landing page.
