How to choose keywords for a reference site on Google?

Before you write your next web page you must ask yourself two questions:

1) on which keywords to optimize your page? 
2) your list of keywords is it relevant to your content and competition?

1) How to prepare a list of keywords relevant?

Some information before you begin your search:

Internet users tend to type their keywords without accent and type expressions words from February to April . 
Look no A keyword but several words / phrases and their variants . The search engine Google is smart enough to interpret misspellings, synonyms, singular / plural ... For info, type "  ~ keyword  "in Google to find synonyms of your query:

To choose your keywords, do not trust your intuition, great free SEO tools exist and will be required:

Google Adwords Keyword Tool : This tool must be the basis of your research. Start by setting your search: Enter a keyword, phrase or skipping several lines. Define / area (s) and geographic / language (s) which limit your search:

Once you're done, download the data in CSV format for Excel:

Try to get a hundred words / phrases and copy the results into Excel to categorize. Feel free to repeat the process several times on different search terms if necessary.

Give a score of relevance to these results 0-3: the keyword is more niche and specific to the subject of the page, the more it tends to 3. A keyword that does not match your business takes a 0, it is interesting to keep track of irrelevant keywords and insert them to the list of negative keywords if you do a Google Adwords campaign . 
Finally, organize your columns "Note" in descending order, by "number of searches" in descending order and alphabetical order to detect duplicates.

You do not determine the primary keyword of your list? Think a keyword will be more / less desirable in the near future? You want to optimize your page for a specific season of the year? Several data sources are strong in this area:

Google Trends or Google's search for insight (which I personally prefer , the statistics are more accurate results and better presented, see below)

To identify emerging trends on which opportunistic sites and pro-active could happen in the TOP position , it is important to know what's going on Mediasphere (Social Media Sphere in English).

Here are some nice tools to find out how many times your keywords appear in the content, conversations, blogs, forums, RSS: Twist See Trends in Twitter and Facebook Lexicon let you know the trends for keywords present on the tweets and the Facebook walls of surfers. You can compare up to 5 patterns between words / phrases with a comma.

2) Have I been realistic? Competition is not it too increased?

The main thing is done, but not everything is finished! He will now have to verify that your keyword list is not too ambitious ...

Go to Google , type your keywords and look below the search bar the number of results. You will have a first estimate of the level of competitiveness for this query . However, any self-respecting SEO knows that this is obviously not enough to determine optimal positioning of your page on this request.

A few years ago you could go for if there were less than 20 000 results by making a good job "on page" (titles, meta tags, visible content, hierarchy). 
Between 20 000 and 000 500 results, it was a little more complicated, but not impossible by trying to optimize its SEO "off page." 
If there were more than 000 500 results, it is necessary to call Amazon or make a phone call to Larry 8)

But today, do not be afraid of the number of results even if it has six zeros! For reasonable requests (not too generic), it is realistic to try it if (and only if) a large part of sites are not optimized for the query typed . 
, it is essential to understand what proportion of optimized on millions of sites proposed sites , thousands or tens only?

I did not make myself clear? Example in picture:

Not bad the first position on a query that generates more than 2.5 million non-performance? In view of this pagea referrer remained in the 90syour grandmother would get on his knees before me so that I reveal my secrets to her great SEO consultant !

You can tell your grandmother that she can keep her joints ... the competition was not so dense on the term "optimize email code" 
For how many pages are optimized for the application you can use Google commands: - inurl: "keyword" to find out how many pages have the keyword in the url, - allintitle: "keyword" to find out how many pages have this keyword in the title - allinanchor: "keyword" to see how many pages have this keyword in the anchor text of links pointing to this page. then You will know the number of sites that have placed these keywords in their titles , their urlss and in anchors their backlinks , three key factors SEO! If there are more than 100 optimized pages on your keyword, it looks a little more complex and you have to work on all SEO factors seem to expect the first page.

Example in picture:

But all is not always as easy as ... How do I know if the sites are optimized "dépassables"?

Type your keyword on Google and analyze the first results : 
- if your request relates to the SEO and sites that appear are the reference sites in the area asWebrankinfo , first position or blog jvweb , it looks very difficult ...

- For other sites known as "dépassables" analyze to bottom: number of backlinks, word (s) key (s) in the domain or url in the title ...

You'll have a real idea of ​​the level of competitiveness in this term and your chances of appearing on a single keyword.

Optimize, stay optimistic and see you on the first page!
