Canonical Meta Tag
Some search engines penalize websites for having multiple URLs with seemingly identical content. The canonical meta tag tells search engines which page to index when there are multiple URLs that have identical or very similar content. Using the canonical meta tag can improve your site ranking and aggregate pageviews.
For example, if your catalog is configured to include the category path in product URLs, your store will generate multiple URLs that point to the same product page.
You can avoid this situation by omitting the category from the URL, or by using the canonical meta tag to direct search engines to index either products or categories.
Use Canonical Meta Tag
To enable the canonical meta tag:
- From the Admin menu, select System > Configuration.
- In the Configuration panel on the left, select Catalog.
- In the Catalog section, click to expand the Search Engine Optimizations section. Then, do one of the following:
- If you prefer that search engines index only pages with the full category path, set Use Canonical Link Meta Tag for Categories to "Yes." Then, set Use Canonical Link Meta Tag for Products to "No."
- If you prefer that search engines index only product pages, set Use Canonical Link Meta Tag for Products to "Yes." Then, set Use Canonical Link Meta Tag for Categories to "No."
