1. WDF? How to find the most relevant keywords on a page.

Are your web pages relevant to the right keywords? Do search engines find the right keywords on your web pages? Which keywords do your competitors consider as important? The new WDF Relevant Keywords Analyzer in SEOprofiler has the answers to these questions.

Introducing the new WDF Relevant Keyword Analyzer

The new WDF Relevant Keyword Analyzer in SEOprofiler determines the most relevant keywords on a web page. Just enter the URL of a web page and get immediate results:

WDF Relevant Keywords Analyzer

The tool shows the WDF, the keyword density based on words, the keyword density based on characters and the total frequency of the keywords on the analyzed page.

WDF: keyword density with an extra twist to get better results

WDF is the abbreviation for "Within-Document Frequency". The WDF value tries to determine the most relevant words of a text. In contrast to the keyword density, the WDF is not calculated through a simple rule of three.

The WDF formula contains two logarithms that make sure that the value cannot be manipulated by over-using the keyword on a page.

The WDF formula is:

In this formula, i is the keyword, j is the page, L is the total number of words on the page and Frequ(i,j) is the frequency of the keyword on the page.

This looks complicated but it's rather easy. Think of WDF as some kind of 'normalized' keyword density value with an extra filter to get better results. The higher the WDF, the more relevant is a keyword. The maximum WDF is 1.00.

Note that there is no perfect WDF value that a keyword should have. The different WDF values help you to compare the relevancy of different keywords on a page.

Find the topical focus of your pages

The WDF Relevant Keywords Analyzer helps you to find the most relevant keywords of a web page. You can find out which keywords your competitors consider as important, and you get new keyword ideas for your own website.

You can find the new WDF Relevant Keywords Analyzer in the 'Keywords' section in SEOprofiler.

2. Internet marketing news of the week

GoogleGoogle updates Penguin, says it now runs in real time within the core search algorithm

"After a nearly two-year wait, Google’s Penguin algorithm has finally been updated again. It’s the fourth major release, making this Penguin 4.0. It’s also the last release of this type, as Google now says Penguin is a real-time signal processed within its core search algorithm. [...]

The last Penguin update, Penguin 3.0, happened on October 17, 2014. Any sites hit by it have waited nearly two years for the chance to be free.

Those long delays are now to be a thing of the past, according to Google. With this latest release, Penguin becomes real-time. As Google recrawls and reindexes pages — which happens constantly — those pages will be assessed by the Penguin filter. Pages will be caught and/or freed by Penguin as part of this regular process."

Everything you need to know about Google’s ‘Possum’ algorithm update

"For those of you wondering what 'Possum' is, it’s the name we in the local search community decided to give the massive Local algorithm update that happened September 1, 2016. [...]

All the evidence seems to indicate this particular update only impacted ranking in the 3-pack and Local Finder (AKA the local results or Google Maps results). We are still seeing a lot of fluctuation, which is making me think Google is still A/B testing various ranking signals."

John Mueller12 companies hit with a Google manual penalty

"Just in case you’re ever tempted to try a few black-hat practices to manipulate your search positions in Google, here are 12 tales to persuade you otherwise. [...]

Whether using cloaking, unnatural paid-for links, doorway pages, spam or hidden links, Google is swift and brutal with a manual penalty. Even if the transgression isn’t necessarily your own fault."
