How much does Google use the Keywords Meta tag in main search results? ” Basically not at all”, according to Matt Cutts a Google software engineer. Too many people have spammed the Meta Keywords tag, so Google doesn’t use the tag to rank sites in their index at all (though other search engines might).
The focus of optimizing your Meta Tags should then be on improving your website’s descriptions. If you have created a good Meta Description and it is useful, the information contained within the tag might be shown as a snippet within the search results page. If your tag is well written and is relevant, the Meta Description can help improve the quality and quantity of traffic to your site by increasing your site’s SERP click through rate.
Here a few things to keep in mind to help create better Meta Tag Descriptions.
Make each description unique. Each description should accurately describe the page. Site level descriptions are allowed, but should be used in places like the home page and other main category pages. All other pages found within your website should use page-level descriptions that reflect the content of each page. The Meta Description doesn’t always need to be in sentence format and can include bits of information. If your page is about a product, the Meta Description is a great place to aggregate pricing, manufacturer or other important product information.
If you are struggling with your Meta Descriptions, start by summarizing the page in a sentence or two. You want to tell a potential visitor what the page is about and the information they will find if they choose to visit. You may also find yourself having to rewrite all of your site’s descriptions, but tackle just a few a week and over time all your site’s Meta Description tags will be unique and more in-line with Google’s webmaster guidelines.
