Here are more detailed tips for creating a best website for Google Adsense.
Give visitors the information they’re looking for
Provide high-quality content on your pages, especially your homepage. This is the single most important thing to do. If your pages contain useful information, their content will attract many visitors and entice webmasters to link to your site. In creating a helpful, information-rich site, write pages that clearly and accurately describe your topic. Think about the words users would type to find your pages and include those words on your site.
Make sure that other sites link to yours
Links help Google crawlers find your site and can give your site greater visibility in its search results. When returning results for a search, Google uses sophisticated text-matching techniques to display pages that are both important and relevant to each search. Google interprets a link from page A to page B as a vote by page A for page B. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.”
Keep in mind that Google algorithms can distinguish natural links from unnatural links. Natural links to your site develop as part of the dynamic nature of the web when other sites find your content valuable and think it would be helpful for their visitors. Unnatural links to your site are placed there specifically to make your site look more popular to search engines. Some of these types of links (such as link schemes and doorway pages) are covered in Google Webmaster Guidelines.
Only natural links are useful for the indexing and ranking of your site.
Make your site easily accessible
Build your site with a logical link structure. Every page should be reachable from at least one static text link.
Things to avoid
Don’t fill your page with lists of keywords, attempt to “cloak” pages, or put up “crawler only” pages. If your site contains pages, links, or text that you don’t intend visitors to see, Google considers those links and pages deceptive and may ignore your site.
Don’t feel obligated to purchase a search engine optimization service. Some companies claim to “guarantee” high ranking for your site in Google’s search results. While legitimate consulting firms can improve your site’s flow and content, others employ deceptive tactics in an attempt to fool search engines. Be careful; if your domain is affiliated with one of these deceptive services, it could be banned from Google index.
Don’t use images to display important names, content, or links. Google crawler doesn’t recognize text contained in graphics. Use ALT attributes if the main content and keywords on your page can’t be formatted in regular HTML.
Don’t create multiple copies of a page under different URLs. Many sites offer text-only or printer-friendly versions of pages that contain the same content as the corresponding graphic-rich pages. If your site has identical content that can be reached via different URLs, there are several ways of indicating the canonical (preferred) version of a page.
If you have a single page accessible by multiple URLs, or different pages with similar content (for example, a page with both a mobile and a desktop version), Google sees these as duplicate versions of the same page. Google will choose one URL as the canonical version and crawl that, and all other URLs will be considered duplicate URLs and crawled less often.
If you don’t explicitly tell Google which URL is canonical, Google will make the choice for you, or might consider them both of equal weight, which might lead to unwanted behavior, as explained below in Why should I choose a canonical URL?
A canonical URL is the URL of the page that Google thinks is most representative from a set of duplicate pages on your site. For example, if you have URLs for the same page (for example: example.com?dress=1234 and example.com/dresses/1234), Google chooses one as canonical. Note that the pages do not need to be absolutely identical; minor changes in sorting or filtering of list pages do not make the page unique (for example, sorting by price or filtering by item color).
The canonical can be in a different domain than a duplicate.
When Googlebot indexes a site, it tries to determine the primary content of each page. If Googlebot finds multiple pages on the same site that seem to be the same, it chooses the page that it thinks is the most complete and useful, and marks it as canonical. The canonical page will be crawled most regularly; duplicates are crawled less frequently in order to reduce Google crawling load on your site.
Google chooses the canonical page based on a number of factors (or signals), such as whether the page is served via http or https; the user’s declared preferred domain; page quality; presence of the URL in a sitemap; and any “rel=canonical” labeling.
You can indicate your preference to Google using these techniques, but Google may choose a different page as canonical than you do, for various reasons.
Different language versions of a single page are considered duplicates only if the main content is in the same language (that is, if only the header, footer, and other non-critical text is translated, but the body remains the same, then the pages are considered to be duplicates).
Google uses the canonical pages as the main sources to evaluate content and quality. Google Search result usually points to the canonical page, unless one of the duplicates is explicitly better suited for a user: for example, the search result will probably point to the mobile page if the user is on a mobile device, even if the desktop page is marked as canonical.
