The meta description meta tag is considered to be a tag useful to use on web sites, whether they are large or small. For a small web site (<50 pages), it’s entirely feasible to write the meta descriptions by hand. What happens, though, when we’re talking of a web site with hundreds or even thousands of pages (online stores, large publishing web sites)?
A first solution is to automatically take the first sentence in the description/text of the page. The problem with this approach is that the sentence an article starts with is likely to have much more or much less than the recommended size of 110/130 (minimum) to 155/165 (maximum) characters with symbols. In this case, my advice is to avoid using the meta description at all and just let Google determine itself what’s the best text to take from the page.
I want to present, in this article, a second solution for creating meta descriptions for large web sites.
