We help you optimize your page for relevance to a given topic or keyword by using algorithms and data science to assist you.
Using our tool you can quickly get a list of terms and phrases used by the top 20 websites that already rank for your topic or keyword of interest. We believe that our version of the TF-IDF algorithm is the way to go in getting you the best list of terms and phrases to include in your copy to boost your rankings and be up there next to the top in the ranks.
Often when writing content, you are focused on the task at hand and write using ideas that follow a natural progression. For SEO the focus is also on writing high quality topically relevant content. Using our tool you can get a list of terms and phrases beforehand, so you know you haven’t missed any essential subtopic or related topic for the topic you are targeting.
Compare your use of the keyword and other terms with your competitors to ensure that you are not overusing keywords. Keyword stuffing is viewed negatively by Google, and you may get penalized for it.
Even if your focus is not content right now, you can use our tool to figure out all the best semantically related keywords in relation to the main keywords you are targeting. These keywords go well beyond "People also ask" and "Searches related" provided by Google.
Quickly figure out what you are missing that they are targeting. This may even help you uncover some keywords and boost your rankings in an off-page context too.
All computations are run on our servers, not your machine.

TF-IDF is a measure of relevance, unlike keyword density which is a measure of frequency. It is a measure of how closely related any content is to what the user is actually searching for.
TF-IDF is an old, well known algorithm in Information Retrieval. We believe that TF-IDF in its basic form is not usable at all. For anyone to effectively use it, they would require to be able to index all of the sites that make up the internet.
The algorithm we use is a TF-IDF variation at heart, but we have used other information retrieval principles, added a proprietary method of weighting and refined it to be a better substitute than base TF/WDF IDF algorithms.
We use it to try to figure out how Google calculates which websites should rank for a particular keyword based on their content.
We do this by essentially reverse engineering the process. We take the top 20 websites that already rank for the keyword and figure out their TF-IDF scores for that keyword and then go ahead and get all the statistically important terms and phrases that are found in their content.
Our algorithm weeds out some words and phrases and cleans up the data and then generates a list of phrases that are sorted by their TF-IDF scores.
Once the analysis is complete, we provide you with a clear list of terms you have missed in your content, terms that need improvement and terms that you have overused and may lead to a penalty.
For a simple overview of TF-IDF and how to use it, please see our article

We get ranking data for all countries that Google supports. Simply enter the country of choice when running the analysis.
Yes absolutely! Select none as an option instead of URL or content and you can run TF-IDF analysis for your target keyword and get the list of all important terms related to that keyword.
We think this will help you get a list before you even start writing content, so you can make sure not to miss any important category or sub-category.
For content analysis we recommend a minimum of 500 words. In our beta tests, content analysis below this threshold was not very useful.
Alternately if you have less than 500 words, you can select none as an option instead of content and do a TF-IDF analysis on competitors content to get a list of important terms.
This may help you get more ideas for more content and then you can do further content analysis after you've crossed about 500 words.
We currently support Paypal. You can use any credit card or a bank account and pay securely using Paypal. We do not store any of your credit card or bank information.
We focus only on content relevance and nothing else. We have used our proprietary version of TF-IDF and honed our algorithm to be the best TF-IDF variant out there.
We recommend starting with Missed Opportunity and incorporating two and three word terms from that list into your content. Use only terms that make sense to you. We do not recommend trying to achieve a certain count of these terms in your content. As long as they are there you are increasing your relevance. We do not place that much emphasis on word count and keyword count as these are outdated concepts. We recommend aiming for high quality content and using terms that flow naturally. If one of the Missed Opportunity terms does not seem right to you, do not use it.
Once you are done with incorporating Missed Opportunity terms, re run the analysis. Now you can move on to Potential Penalty and Needs Improvement.
