The title of a page tells users and search engines the topic of the page. The tag ‘title’ tag must be placed inside the ‘head’ of the HTML document. The ideal would be to create unique titles for each of the pages that make up the site.
If your site will appear in the results, what has been written inside the title tag will be the first line of the result. The user search terms appear in bold. This will help users figure out if that page is what they were looking for.

The title of the homepage, for example, could be the name of your site / business and may include other information such as its location or some of its most important goals or offers.

The titles of the other pages should accurately describe the content of the page and include the name of the site or enterprise.

Tips for the title tag:

•     The title should describe the page content – You must choose a title that effectively communicates what is the argument of which is the paginaEvitare of:

a. choose a title that has no connection with the contents of the page
b. use a default value as “Untitled” or “New Page 1″

•     We need to give a unique title for each page – Each page should have a different title, to help Google understand that the page is different than the others that constitute the site.

Avoid using the same tag ‘title’ for all pages or whole sections of the site

•     Use short but descriptive titles – Titles can be concise and clear. If the title is too long, Google will display only a portion of its results.

Avoid using excessively long titles that do not help users or cluttering the title of keywords is not necessary.

The meta description tag of a page gives Google and other search engines a summary of what the page is talking about. Considering that the title of the page can be long or a short phrase, the description of a page may be one or two sentences or a short paragraph.

Google Webmaster Tools provides a handy section of “content analysis” that provides information on the meta-tags that are too short or too long, or duplicated too many times (the same information is also provided for the tag ‘title’).

Just like the tag ‘title’ even the meta tag ‘description’ is inside the tag ‘head’ of the HTML page.

The meta description tag is important because Google might use it as a snippet (snippet of text that appears in Google searches after the link to the site). Notice the “may”, because Google may choose to use as a piece of text snippets most relevant to your search. Google could also use the description provided in the Open Directory Project if the site is listed there.
Add a meta description tag for each page is a good practice if Google can not find a piece of text to use for the snippet.

The words in the snippet of text in bold when they appear in the user’s query. In this way the user has more clues to whether the content of the page corresponds with what I was looking for.

Tips for the meta tag ‘description’

• Concisely summarize the contents of the page – Write a description to inform at the same time arouse the interest to see if the description page of search results.

Avoid:
a. write a description that has no connection with the contents of the page
b. using generic descriptions like “this is a web page”
c. fill the description of keywords
d. copy and paste the full content of this page in your meta tags

• Use unique descriptions for each page – have a different description for each page helps users and Google, especially in searches where users can visit most pages on the same domain. If the site has hundreds or thousands of pages manually write the descriptions becomes complicated. In this case better to automatically generate descriptions based on the content of each page.

Avoid using the same meta description tag for all pages or entire sections.

Use words in URLs – URLs with words relevant to site content and its structure are more “user friendly”. Visitors will remember better and be more willing to linking through the pages.

Avoid:

•     URL to use with long and unnecessary parameters and session IDs
•     for pages to choose generic names like “page1.html”
•     excessive use of keywords within a URL

Create a simple directory structure – Use a directory structure to organize well the content of the site and to indicate to visitors where they are. Try to structure the directory to indicate the type of content within the given URL.

Avoid:

•     the ‘nesting of subdirectories like “…/dir1/dir2/dir3/dir4/dir5/dir6/pagina.html”
•     to use for directory names that have no relation with the content

Provide a single version of a URL to access a specific page – In order to prevent some users linkino to a version of a URL and other linkino a different version (this could split the “reputation” of those contained in the URL) trying to use a single URL in the structure and internal linking of your site.

If you notice that users are accessing the same content through multiple URLs, a good solution is to create a 301 redirect from the URL you want to it.

Avoid:

•     to have pages of subdomains and root directory (eg “domain.com / page.htm” and “sub.domain.com / page.htm”) that access the same content
•     cross versions of the URL with www. and without www. in internal links to pages on your site
•     Use both uppercase and lowercase in URLs (many users expect URLs written in all lowercase and better remembered)

In recent times in various forums or news groups you are talking about the very fact that for over 2 months Google updates the pagerank of the sites on your toolbar.

After everything was said and done (meetings, conferences, forums, etc. ..) on the importance of PageRank for the optimal positioning of a website, it seems the world of SEO is collapsing a myth!
There is debate about whether in fact its importance is increasingly irrelevant if anything … In short it seems that the pagerank is finally dead! In fact we also make several assumptions about why it might be or might be because instead of false assumptions, but only a delay in updating their Google toolbar for various reasons. If sometimes go deeper you find an interesting blog that I discovered on the network.

The fact remains that ch deals with SEO’s aperfettamente that beyond the death of pagerank or not a work of “linking” of a site on other sites, it certainly has its advantages in terms of visibility

Google has announced in recent days, an “adjustment” down the costs for its advertisers and further increase the visibility of text ads that are placed in the new free mail service Gmail is currently being tested on the circuit as well as Adsense .

The planned adjustment, according to submissions from the top of Google, will be allowed by a mechanism that will make an estimate of clicks received, and cost adapt gradually trying to maximize your ROI. Basically the keywords and sloogan that generate less traffic and will be considered less efficient, will automatically have a lower CPC, thus increasing the number of available clicks for keywords that will generate more traffic.

Furthermore, the costs will be varied according to the importance of the context in which the ads appear: “A click received from a page where there is a review of a product related to the spot is certainly more important than that received by a generic page” claim always Google.

Although we have still not clear how this mechanism will work, but we can say that Google recently is responding faster and faster to changing market and especially the movements of competition proving definitely a company that tries to constantly satisfy the needs of its customers.

All this movement in the competitive world of search engine marketing I think is very positive even though Google, right now, is it still a cut above all his rivals.
