I'm not in the contest, but if I was - I'd be SKEEEEERED. This was awesome, really - there were MAYBE 3 things I knew... The rest was new. I'm lame that way. The great thing about this is that as a blogger - you've covered ideas I've never thought of...I get my traffic mostly from SEO (not on my blog, but in my websites which are product based review sites) - but there's enough meat in this post I can use for my niche sites to keep me in the black, so to speak (ink I mean, not socks). Awesome post, Brankica - I'm speechless. (If you ignore the foregoing paragraph.)

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.
Do you have a content strategy in place, or are your efforts more “off the cuff?” Not having a clearly defined keyword map can spell trouble — especially if two or more pages are optimized for the same keyword. In practice, this will cause pages to compete against each other in the SERPs, potentially reducing the rankings of these pages. Here is an example of what this might look like:
The Google, Yahoo!, and Bing search engines insert advertising on their search results pages. The ads are designed to look similar to the search results, though different enough for readers to distinguish between ads and actual results. This is done with various differences in background, text, link colors, and/or placement on the page. However, the appearance of ads on all major search engines is so similar to genuine search results that a majority of search engine users cannot effectively distinguish between the two.[1]
However, this may not be the case for your company or your clients. You may start by looking at keyword rankings, and realize that you’re no longer ranking on the first page for ten of your core keywords. If that’s the case, you quickly discovered your issue, and your game plan should be investing in your core pages to help get them ranking again for these core keywords.

By far the best rank tracking software on the market. We’ve tested a variety of different rank tracking softwares and AccuRanker is by far the most precise on the market. As a tool AccuRanker is very intuitive to use and the support is just great. We appreciate the speed and the possibilities regarding filters, tagging and especially the instant refresh function. These features and a bunch others is something we use a lot and I myself has been satisfied using it since 2016.

Secure (https) to non-secure sites (http): Since Google began emphasizing the importance of having a secure site, more websites are securely hosted, as indicated by the “https” in their URLs. Per the security protocol, however, any traffic going from a secure site to a non-secure site will not pass referral information. For this issue, you can correct by updating your site to be secure through a third-party SSL certificate.
