Note - at this point Google already has baseline metrics from other search results. So, if your site beats them by a factor of say 3x then Google thinks - hey.. this page looks to be way better - so why not stick its rankings in the long term and why not even bounce it up higher and see what happens and measure again how users engage with the site?
You can find broken internal links from within the Search Console. You need to attend to each warning appropriately telling Google that you have fixed it. Having excessive 404s will hurt your site if they are really 404s, because anyone could escalate the 404s by pointing randomly to pages that don't exist from external places, which is why this is not that big of a deal - but should be looked at.
Mr. Dean I wanted to drop in and personally thank you for everything you do for us rookies in the online marketing field. I have learned so much from your lessons/guides/articles/videos you name it! I also been using Raven Tools and find it pretty helpful as well in regards to keyword research, what say you? Look forward to all your future posts! Also, it says a lot about you that you actually take the time and respond to the comments that users leave you in your articles, don’t really see that too often these days! All the best!
3) KWFinder is one of the "newer" kids on the block, but it's probably just about the easiest way I have found to find new long-tail keywords quickly. A couple of things I like about this tool is that it allows me to create lists of keywords. So I can group up my different sites by lists and revisit them at a later date. I can export the data to CSV and start building out campaigns. It also keeps a nice scrolling list of the last 20+ keywords you have looked up. The SEO difficulty indicator comes in very handy as well! As far as ease of use goes, KWFinder wins hands down.

I recently decided to go with ahrefs after using spyfu for a couple years and trialing secockpit. I was a moz client for awhile too about a year ago. I found spyfu data to be sketchy (or just plain wrong) fairly often, and moz, I don’t know, just didn’t seem like they were really into supporting what I wanted to know. secockpit was achingly slow for a trickle of data. ahrefs isn’t nearly so graph-y as spyfu, but they are so blazing fast and the data is so deep. I enjoy it a great deal, even if it is spendy.

The experts love SEMrush, but will you? Take the tool for a test drive and decide for yourself. For a limited time I'm giving all my readers an exclusive one month free access to SEMrush PRO. You'll get unrestricted access to all the tool's features. If you decide SEMrush is not for you, cancel anytime during the one month trial and you won't be charged a penny. 
1) SEMrush - I believe that among all the 3rd party software, SEMrush has the largest keyword database. Their search volume data is pretty accurate and aligns with the Google keyword planner. Also, based on the type of content that needs to be produced (i.e. informational, transactional, etc.), one can utilize different filtering options available in it.

You likely have a few keywords in mind that you would like to rank for. These will be things like your products, services, or other topics your website addresses, and they are great seed keywords for your research, so start there! You can enter those keywords into a keyword research tool to discover average monthly search volume and similar keywords. We’ll get into search volume in greater depth in the next section, but during the discovery phase, it can help you determine which variations of your keywords are most popular amongst searchers.

To use this feature, click on the second tab that you will find on the top right bar. Type in the keywords that you want to view the performance of, and also type in the name of your domain.

Once you’re done getting the trust, you’ll want to ensure that your content resonates with your audience and other bloggers. As we know, every of our content on the web is meant for the end user. That said, a good website is bound to see more traffic, better links, higher retention rate, more shares and smaller bounce rates. The bottom line; off-page analysis gives you a better picture of the impression your site leaves on users.

In addition, you can dig into the paid side of search and find out what keywords your competitors are bidding on, and then leverage those keywords for your own organic benefit if you're not already doing so. Search Metrics does this as well, but I've found SEMrush to provide a greater range of keywords and they save more historical keyword data than Search Metrics.
I think people's aresenal of keyword research tools are mostly the same: 1) You need a tool to examine search volume, most likely Google Keyword Planner 2) A tool to help you generate more keyword ideas. Tools that work with the search engines' autosuggestions are very popular such as KeywordTool.io and Ubersuggest 3) Then people might add a tool broaden the depth of their data, maybe including something like Google Trends or Moz's Keyword Difficulty tool.
You can improve your site speed by a ton of methods, but the overall goal should be to test your site from different geo-locations using a tool like pingdom and then attend to issues. You could go for a CDN provider like Cloudflare or install caching plugins that speed up your site by reducing database queries and therefore the server load. Choosing the right hosting company for you is a critical decision and is based on many factors including your CMS, expected site traffic, and what your goals are for the site amongst others.
After diagnosing your site through the different facets of the search engine (Google), it’s time for you to check your website as an entity. The tool we’ve always used to check on our site’s onsite status is Screaming Frog. We’ve always used it as the websites we handle grow larger as the months pass by. You set the parameters and it’s even capable of crawling/compiling outbound links to let you know if you have broken links. Here’s what the overview looks like:

To qualify to appear in the snack pack or the resulting local search pages, your business needs to be verified by the Google My Business service, which involves registering, getting a physical post card from Google with a code, validating the code and setting up perfect NAP (Name, Address, Phone Number) data across your site, Google Maps, and other citation services and directory listings.
