Ask for explanations if something is unclear. If an SEO creates deceptive or misleading content on your behalf, such as doorway pages or "throwaway" domains, your site could be removed entirely from Google's index. Ultimately, you are responsible for the actions of any companies you hire, so it's best to be sure you know exactly how they intend to "help" you. If an SEO has FTP access to your server, they should be willing to explain all the changes they are making to your site.
I do not obsess about site architecture as much as I used to…. but I always ensure my pages I want to be indexed are all available from a crawl from the home page – and I still emphasise important pages by linking to them where relevant. I always aim to get THE most important exact match anchor text pointing to the page from internal links – but I avoid abusing internals and avoid overtly manipulative internal links that are not grammatically correct, for instance..
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.
QUOTE: “I don’t think we even see what people are doing on your website if they’re filling out forms or not if they’re converting to actually buying something so if we can’t really see that then that’s not something that we’d be able to take into account anyway. So from my point of view that’s not something I’d really treat as a ranking factor. Of course if people are going to your website and they’re filling out forms or signing up for your service or for a newsletter then generally that’s a sign that you’re doing the right things.”.

ensure redirected domains redirect through a canonical redirect and this too has any chains minimised, although BE SURE to audit the backlink profile for any redirects you point at a page as with reward comes punishment if those backlinks are toxic (another example of Google opening up the war that is technical seo on a front that isn’t, and in fact is converse, to building backlinks to your site).
Your website is the “hub” of your online brand – so, it’s important to have regular checkups to ensure everything is in order. It’s also important to note that your website is a living digital property, it’s typically not stagnant for long periods of time. In any given year, content is added and/or removed from your site. It is for this reason that audits should occur on a regular basis. We recommend that websites be audited at a minimum of once per year. That allows your teams to fix critical issues as they arise.
