Pushing the Frontiers of SEO & Content

Let’s speak content material and on-page SEO — on steroids. Let’s discuss cutting-edge SEO analysis that may actually rework your rating success.

Our discussions over the previous few years have been centered on editorial plans, question intent, and consumer engagement.

While they’re absolutely a component of the equation (and I’m a deep believer of content material high quality, avoiding SEO spam and creating helpful solutions), now we have forgotten an necessary half of getting content material proper: data-driven choices.

I wish to reinvent your definition of key phrase issue. I wish to reinvent your understanding of aggressive evaluation. It is time to actually leverage the newest SEO instruments in your content material creation.

Understanding Page 1 Is the Most Important Ingredient of SEO

Not all key phrases are created equal.

Creating a weblog publish of 1,000 phrases is actually a very good SOP and an environment friendly strategy to temporary your content material writers. However, it’s probably not the proper recommendation for the key phrase for which you are attempting to rank.

Different question sorts want completely different content material. This implies that Page 1 will look radically completely different whether or not you’re on the lookout for “SEO blog”, “buy CBD oil online” or “underground techno club Berlin”.

I wish to invite you to check Page 1 and actually perceive what content material sort, content material size, and key phrase frequency Google want to see.

To obtain SEO success, your key phrase analysis and content material planning want an replace.

Using Statistical Relevance to Understand Successful Websites

The final two years have seen an increase of instruments which can be doing key phrase particular aggressive analysis for you. Statistical evaluation has by no means been simpler — or sooner.

New SEO instruments use statistical evaluation to grasp what all these web sites on Page 1 have in frequent – and for which rating elements your web site is poor. You now get an inventory of statistical related optimizations to make.

The distinction to a standard crawler (like Screaming Frog) is that the correlational SEO instruments don’t show a hard and fast set of hard-coded suggestions.

Their suggestions are primarily based on the statistical relevance of an element in your goal key phrases. It is particular, as an alternative of the “one-size-fits-all” strategy of most crawlers.

Instead of telling your crew “extend this blog post”, now you can inform them: “Extend this piece by 383 words, two images and one video. Make sure to use the exact match keyword twice in H3 and add the following keywords…” – realizing that it’ll transfer the needle, as a result of that is what these web sites on Page 1 have in frequent.

The New Kids on the Blog: The Rise of On-Page SEO Tools

The instruments rising in reputation embrace:

  • CORA
  • Page Optimizer Pro
  • Website Auditor by SEO Power Suite
  • SurferSEO

I’m not an affiliate of any of these instruments, and this evaluation is predicated on my observe of utilizing these instruments in my company work all through the final two years.

These instruments fluctuate on the quantity of search outcomes and rating elements they measure. Some measure a handful of on-page SEO elements, some assessment LSI key phrases with TF-IDF evaluation, others as much as 600 rating elements, together with backlinks.

What to Consider When Implementing a New On-Page SEO Tool

There are three elements I like to think about when implementing a brand new software to my workflow.

For correlational SEO, they’re:

  • Data and transparency
  • Recommendation high quality
  • Usability

Think of all these instruments as your most refined key phrase issue evaluation ever.

If you believed in key phrase density (share of key phrase to complete phrases inside a web page), it used to inform you “use the keyword more.”

Today’s instruments not solely inform you which particular rating elements (headlines, photographs, daring, italics or lists) to optimize – in addition they inform you that these elements are probably to have a constructive impression in your rankings.

Data & Transparency

Firstly, CORA is the solely software that won’t solely assessment the first 100 search outcomes (and due to this fact present the deepest evaluation of search outcomes) but additionally present you the full evaluation. This contains each single web site and the standing of its optimization.

According to the SurferSEO web site, they crawl the first 40 search outcomes to make their on-page evaluation.

SurferSEO and different instruments will offer you the suggestions however not the detailed report of your rivals. This means you gained’t have the ability to reverse-engineer their math – and you’ll have to belief their suggestions with out realizing the underlying knowledge set.

CORA can be the solely software that measures greater than 600 rating elements. With CORA, you possibly can even use APIs (e.g., to Ahrefs) and consider backlinks (whereas the others are pure on-page SEO instruments). It features a distinctive in-depth job checklist which prioritizes the elements that seem to affect rankings the most.

The Rise of On-Page SEO Tools: Pushing the Frontiers of SEO & ContentCORA

CORA is the clear winner on the subject of knowledge supplied and the quantity of rating elements measured.

All different instruments deal with on-page SEO elements solely. Mainly, they’re reviewing the time period frequency of:

  • The actual match key phrase.
  • Variations of the goal key phrases.

But in contrast to key phrase density, they measure the time period frequency per related rating issue corresponding to headlines, paragraphs, daring, italics, lists, and many others.

SurferSEO makes use of round 10 issue sorts and operates extra like a traditional crawler with a hard and fast checklist of elements for which they’re publishing suggestions.

It’s just like this: Website Auditor evaluations 17 on-page elements.

Page Optimizer Pro correlates 29 elements which can be chosen primarily based on SEO analysis and single variable testing. You can assessment the checks behind their displayed elements of their weblog. It additionally contains functionalities to assessment web page structure, media sorts, and schema markup.

All instruments provide an answer for contextual key phrases as effectively. Page Optimizer gives a TF-IDF evaluation, as does Website Auditor. SurferSEO calls them “prominent words”.

Using semantically-related key phrases will assist to extend topical relevance and make it simpler for different pure language processing instruments (and due to this fact, probably, additionally Google) to grasp the intent, matter, and ideas of your content material.

Many SEO professionals have seen a rise in rankings from utilizing key phrase variations and semantically-related key phrases appropriately.

Recommendation Quality

When evaluating the suggestions of a number of instruments, you’ll understand that they by no means return the very same suggestions.

Some will inform you so as to add a key phrase 2x to an H3, and the others will inform you 3x. How can that be, and what does it imply in your optimization?

Disclaimer: Perfect is the enemy of executed. We are aiming for “good enough.”

Correlation isn’t proof. However, it permits us to grasp these elements which have the highest likelihood of making us profitable.

The objective is to not get an “A” or 100 % in all of the instruments. The objective is to knock out these optimizations that can simply put us forward of the curve.

The Rise of On-Page SEO Tools: Pushing the Frontiers of SEO & Content

The first cause for various suggestions throughout instruments is phrase depend per web page – and the way it’s calculated by the crawlers accumulating HTML.

Crawlers corresponding to Google (and these instruments) assessment the supply code of a web site, not the visible entrance finish that we get pleasure from as customers.

This supply code contains header, footer, physique content material, and many others. The instruments have completely different capacities of understanding uncooked HTML supply code vs. rendering HTML.

Google indexes rendered content material, so rendered options usually tend to be nearer to what the Google crawlers are seeing, too.

CORA, for instance, elements in all content material, together with header, footer and even developer feedback by rendering HTML with embedded Chrome.

However, Page Optimizer Pro determines the phrase depend per web page by rendering HTML with a easy browser. Their phrase depend result’s just like the outcomes of SEOquake by SEMrush.

Other instruments may be utilizing uncooked HTML solely.

Keep in thoughts that each one the instruments additionally calculate variations of your key phrases and synonyms, in addition to match phrases in another way. Comparing the variations throughout instruments is commonly like evaluating apples and oranges.

Secondly, the suggestions are primarily based on the knowledge set with which you’re evaluating your web site.

When utilizing Page Optimizer Pro or Website Auditor (in addition to the creators), the advice is to check towards pages of the identical sort. Compare internal pages with internal pages (not homepages), and product pages with product pages (not classes) and so forth.

This means that you’re evaluating your web page towards 5 to 10 rivals of the identical web page sort which can be extra profitable than you.

In distinction, CORA elements in the first 100 search outcomes of all web page sorts, SurferSEO compares 40 search outcomes, and thus the suggestions are normalized throughout content material sorts by the dimension of the knowledge set.

This is very attention-grabbing for the TF-IDF evaluation. TF-IDF permits us to grasp use contextual key phrases (LSI). TF-IDF is time period frequency (key phrase depend) in a doc instances the key phrases utilized in the total set.

In Website Auditor’s TF-IDF and Page Optimizer Pro, we’re manually selecting the rivals that we wish to examine our web site towards. Our guide choices could negatively have an effect on the outcome calculated.

Thirdly, the high quality of suggestions is predicated on the elements which can be included in the softwareand the way they’re prioritized.

Most importantly, the suggestions differ throughout the instruments primarily based on the underlying assumptions that the creators made about the significance of sure rating elements.

Using the completely different instruments, we’re shopping for into the completely different SEO philosophies of the creators:

Which rating elements must be included in the software? Which ones are related for SEO?

SurferSEO and Website Auditor hard-code their suggestions (extra like most crawlers and SEO plugins would do) and thus will return the identical set of elements irrespective of which key phrases are entered. We should not conscious of the reasoning behind the included elements.

Page Optimizer Pro additionally has a hard and fast set of suggestions. However, they had been chosen primarily based on years of single-variable testing by the creators and are up to date repeatedly to replicate the significance of them primarily based on the newest analysis.

CORA contains greater than 600 rating elements, even hypothetical ones, and has no desire on the significance of them. This means the suggestions are solely primarily based on the statistical relevance and can change for each key phrase.

On a continuum from private desire of rating elements to statistical evaluation, we’d discover: Website Auditor and Surfer SEO first, then Page Optimizer Pro after which CORA.


CORA is processing heavy and thus is a desktop utility – as is Website Auditor (which is a web site crawler with some nice content material instruments). Page Optimizer Pro and SurferSEO are browser functions.

Website Auditor is my private usability winner. It is quick, straightforward to make use of and intuitive. I can simply plug in my area, then the URL of the goal web page and key phrase, and I’ll obtain all the suggestions.

websiteauditorWebsite Auditor

It is straightforward to see which rivals are being pulled in and embrace/exclude them from the evaluation if wanted (e.g., in the event that they don’t have the identical web page sort). I can plug a number of goal key phrases into the software to get the full evaluation.

I work largely with Website Auditor as a result of I get pleasure from the course of most.


The second finest software in phrases of usability, I might say, is SurferSEO. It is the flat white of SEO instruments – an attractive browser model, minimalistic and slick.

It permits for a fast high-level evaluation and understanding what a web page would wish. It additionally appears to be like good on a display screen share with shoppers as a result of it doesn’t have the nerdy SEO really feel that some of the crawlers have.

SurferSEO is competing with Page Optimizer Pro for the second place in my private usability desire. I like how Page Optimizer Pro offers an total rating that we are able to observe over time and see enhancements.

pop2Page Optimizer Pro

I additionally discover Page Optimizer Pro most useful and helpful to temporary my content material writers. It returns an inventory of suggestions, together with phrase depend, media gadgets to make use of and optimize on-page SEO elements.

I can see how, with a bit of coaching, this software can be utilized on a day-to-day foundation by a content material author crew with low to intermediate SEO data.

While CORA gives the most insights, it’s going to want a detailed-focused SEO professional to interpret the output. Many features should not self-explanatory, and the big Excel recordsdata might be overwhelming at first.


And the Winner Is…

We have checked out:

  • Data and accuracy
  • Quality of suggestions
  • Usability

So, which one is the finest on-page SEO software?

The reply will depend on your private preferences, your position in the crew, and for which half of your SEO course of you’re planning to make use of the software.

It will depend on your desire for:

  • Detailed knowledge vs. overview
  • Statistical related suggestions vs. finest case practices
  • Complex in-depth stories vs. straightforward utilization and sensible implementation

For a high-level overview, display screen shares on a shopper name and dwell displays to the crew or different stakeholders, I like to recommend SurferSEO or Website Auditor.

They will make you look good. You will have the ability to justify a data-driven technique – with out wanting like an entire nerd. Those instruments make it straightforward to promote your suggestions – since you wish to consider them.

But don’t overlook that we don’t have any perception into their knowledge assortment or the precedence they assign to the displayed rankings elements.

They are correlational SEO for learners (not less than for now) or gross sales/advertising and marketing individuals who don’t wish to dig into each element.

If you need your SEO and content material crew to make data-driven choices, exact on-page SEO updates and use contextual key phrases effectively, educate them use Website Auditor or Page Optimizer Pro.

Working with Page Optimizer Pro will help you future-proof your key phrase analysis and content material planning. Your content material briefings and content material upgrades shall be extra particular than ever earlier than, leveraging rating elements which have confirmed their relevance in a sequence of in-depth SEO testing.

Page Optimizer Pro (or POP as insiders name it) makes your content material creation actually data-driven and lets you perceive what profitable web sites are doing proper.

If you’re engaged on advanced SEO campaigns in aggressive niches, or when you merely wish to actually geek out on rating success in 2019, CORA is your finest wager.

While it’s arduous to make use of, it gives by far the finest knowledge and deepest perception. It is the solely software that’s totally clear and creates a fluid job checklist primarily based on statistical relevance solely.

So, are you…

  • An overview individual making an attempt to get an summary of the optimization wanted for a web page?
  • An SEO professional creating detailed content material plans?
