40 secret keyword research tools to find the million dollar keyword

free keyword research tool
Some of the most popular keywords, which Google suggests, regarding keyword tools are "keyword research", "keyword spy", "keyword generator", "keyword finder", "keyword discovery", "keywords search" and "keywords for SEO". I decided to tell about some tools, which i use for certain aspects of keyword research. The keyword research tools i tell about have all in common, that they aren't well-known as e. g. Übersuggest, but they accomplish exactly so good if not better the same tasks, as established commercial and free tools.

What are the main keyword research tasks a SEO and SEA use to do? The tasks are different (better optimizing, saving money, out-competing of competitor), but the primal goal of keyword research is always the same: to get more cheaper targeted traffic. A SEO is looking for keywords for optimized page or analyzes the competitor's landing page. A SEA is looking for keywords for an ad and for the landing page, or analyzes competitor's ad and landing page. Lets further look, which keyword research tools could be helping in this (only free tools and no affiliate links, promised:)
Your first and last keyword research tool must be always the AdWords keyword tool. Not cause we love Google, but cause only there you get the Google's view on the main metrics of an analyzed keyword: traffic, CTR, click price.

Well-known keyword research tools

I begin with listing of the keyword research tools, which are in my opinion well-known - the common knowledge state can vary, so don't hesitate too look on the list of well-known products, you could find some tool, which you personally never seen and used before and which will make your day.

The whole bunch of sophisticated freemium or commercial market-dominating tools like MOZ, Majestic SEO, Ahrefs, Raven, SEMRush, Searchmetrics, Kissmetrics etc. Every tool has advanced keyword research and analyzing possibilities and each SEO business must use at least one of them.
Then come well known tools, both performing keyword research as single task and doing keyword research as a part of a suite of SEO tools:
Keyword research tools provided by Bing are well-known too, but they require for full functioning an Excel:
Keyword research tools from Google are such well-known - i will not mention them here. Maybe beside of a single one:
Regarding keyword research this tool is interesting not because time ranges, but because you get to your queried keywords other keywords, are topical field related AND are mostly queried with your query.
Here I've finished up with known keyword tools and with a feeling of fulfilled duty begin with

Keyword research tools outside mainstream

Browser (Firefox) extensions for keyword research

1. KGen
KGen calculates word lists by frequency of any page, where it is turned on. Lists can be sorted and exported. Beside of this it calculates the weight of each word in the list. The weight parameter is computed on basis of the place in the page's source code: a word appearing in title has more weight as the same word in the paragraph. In the KGen options you can manipulate the weight, associated with each HTML attribute, create own lists of ignored words and some other individualizations. On data basis of KGen you can make reasoned decisions about improving of own texts and make insights into competitor's texts.

2. ClearForest Gnosis
ClearForest Gnosis analyzes page in real time, whether any keyword on the page is located as entity in a bunch of other internet media. If yes, the keyword(s) are underlined and the extension creates a synced media list. The media list, which are queried, contains beside of Wikipedia, main USA news sites, but can you can change it in the options through deleting or adding of own media URLs. Don't let you warp from using of this extension through the last negative review at Firefox's extensions page. In fact, the support site gives 404 out, but the extension works, on the latest Firefox 31 too - i've tested it. You must just wait some seconds: the extension needs time to parse all sources.
