how to setup multiple filters in search console

Yes, against different answers of some experts in the Google product forum, like here or there. The possibility to set multiple filters is extremely useful and works into both directions - you can include or exclude multiple keywords, urls, traffic sources - anything, what you want.

We will operate with filter settings through manipulation of urls. You'll need for this a good code editor - good means Notepad++, one magic plugin for it, and, surely, a bit of chutzpah - yeah, we'll do the big G, nothing less!

Free online SEO tools for TF-IDF calculation

Free online tools for TF-IDF calculation
First of all: what's TF-IDF? In German this content parameter is called WDF / IDF, but the subject is the same:

TF-IDF, term frequency–inverse document frequency, is, explained in short, from rookie to rookie, the relation of term usage frequency in the given document to usage frequency of this term in all documents containing it.

This relation mirrors how relevant is the given document for the given term in the manifold of all documents containing this term.

TF-IDF is successor of keyword density. Some non-demented SEO geriatrics can remind, what means keyword density: number of term's usage in the text divided through the number of all words in the text multiplied with 100. This formula is in reality both most used and wrong.

Well, i'm not your Wiki, and if you're in the full legal age and not banned by Google, you would find fast everything you need to know about keyword density and TF-IDF. I just say: nowadays TF-IDF is nearly the single numeric parameter of content quality. But this article is about something other - i've promised to share some freebies, right?

Solution: how to avoid Google's crawling and indexing non-existing pages

Many webmasters are affected from the weird issue: Google is indexing (at least crawling) non-existing URLs. The issue isn't depending of whether one uses Wordpress or other CMS. This question about why Google is crawling and / or indexing non-existing URLs appears in all webmaster forums, Google Groups and so on, but without a clear solution.

The fact, that Googlebot creates and crawls a bunch of non-existing URLs, lets arise some questions:

  • Where non existing URLs are coming from?
  • Why is it not optimal, if non-existing URLs are crawled respectively indexed?
  • How to minimize risks related to non-existing URLs?

Making decision: hosting of javascript libraries on external CDN or locally

whether to host javascript libraries locally or at external javascript cdnThe benefits of hosting common JavaScript libraries externally at JavaScript CDN are well known - i list them just in short: external hosting of JavaScript libraries
  • reduces own server's traffic
  • makes parallel loading possible
The first question is: where to host? Directly on library vendor's site? Or somewhere else? There are mainly two factors, which let us make a decision, where we host our JavaScript libraries:
  • Speed
  • Popularity
The second question is more general: whether to host externally? Or locally?
Lets look on some details, which help to choose an optimal public hosting of common JavaScript libraries.

  • If you doubtlessly want to host JavaScript libraries externally, host them at Google Hosted Libraries - so you get highest chance, that your visitors have them already in chance and don't need to download them again.
  • If you doubt, host better your JavaScript libraries locally - visitors, who have JavaScript libraries in cache are very few, and the average visitor gets the data on fastest way.
