However, if possible, I would like you to expand a bit on your “zombie pages” tip..we run a site where are definitely enough pages to delete (no sessions, no links, probably not even relevant with the main theme of the site, not even important for the architecture of the site)..Nonetheless, I am not very sure what is the best technical decision for these pages…just deleting them from my CMS, redirecting (if there is a relevant alternative) or something else? Unindex them on Search console? what response code they should have? ..
An SEO expert could probably use a combination of AdWords for the initial data, Google Search Console for website monitoring, and Google Analytics for internal website data. Then the SEO expert can transform and analyze the data using a BI tool. The problem for most business users is that's simply not an effective use of time and resources. These tools exist to take the manual data gathering and granular, piecemeal detective work out of SEO. It's about making a process that's core to modern business success more easily accessible to someone who isn't an SEO consultant or expert.
However, you may encounter pages with a large amount of spammed forum discussions or spammed user comments. We’ll consider a comment or forum discussion to be “spammed” if someone posts unrelated comments which are not intended to help other users, but rather to advertise a product or create a link to a website. Frequently these comments are posted by a “bot” rather than a real person. Spammed comments are easy to recognize. They may include Ads, download, or other links, or sometimes just short strings of text unrelated to the topic, such as “Good,” “Hello,” “I’m new here,” “How are you today,” etc. Webmasters should find and remove this content because it is a bad user experience.
The caveat in all of this is that, in one way or another, most of the data and the rules governing what ranks and what doesn't (often on a week-to-week basis) comes from Google. If you know where to find and how to use the free and freemium tools Google provides under the surface—AdWords, Google Analytics, and Google Search Console being the big three—you can do all of this manually. Much of the data that the ongoing position monitoring, keyword research, and crawler tools provide is extracted in one form or another from Google itself. Doing it yourself is a disjointed, meticulous process, but you can piece together all the SEO data you need to come up with an optimization strategy should you be so inclined.
Where the free Google tools can provide complementary value is in fact-checking. If you're checking out more than one of these SEO tools, you'll quickly realize this isn't an exact science. If you were to look at the PA, DA, and keyword difficulty scores across KWFinder.com, Moz, SpyFu, SEMrush, Ahrefs, AWR Cloud, and Searchmetrics for the same set of keywords, you might get different numbers across each metric separated by anywhere from a few points to dozens. If your business is unsure about an optimization campaign on a particular keyword, you can cross-check with data straight from a free AdWords account and Search Console. Another trick: Enable Incognito mode in your browser along with an extension like the free Moz Toolbar and you can run case-by-case searches on specific keywords to get an organic look at your target search results page.
QUOTE: “To summarize, a lack of helpful SC may be a reason for a Low quality rating, depending on the purpose of the page and the type of website. We have different standards for small websites which exist to serve their communities versus large websites with a large volume of webpages and content. For some types of “webpages,” such as PDFs and JPEG files, we expect no SC at all.” Google Search Quality Evaluator Guidelines 2017
The self-service keyword research tools we tested all handle pricing relatively similarly, pricing by month with discounts for annual billing with most SMB-focused plans ranging in the $50-$200 per month range. Depending on how your business plans to use the tools, the way particular products delineate pricing might make more sense. KWFinder.com is the cheapest of the bunch, but it's focused squarely on ad hoc keyword and Google SERP queries, which is why the product sets quotas for keyword lookups per 24 hours at different tiers. Moz and Ahrefs price by campaigns or projects, meaning the number of websites you're tracking in the dashboard. Most of the tools also cap the number of keyword reports you can run per day. SpyFu prices a bit differently, providing unlimited data access and results but capping the number of sales leads and domain contacts.
What does it mean for a site to be SEO friendly? It goes beyond just posting quality content (though that’s a very important part!). There are all kinds of ways big and small that can prevent your site from being seen by search engines and thus by users. Our free audit tool begins by looking at some of the most important facets of your website you might not even be aware of.
