We see occasional questions, in Blogger Help Forum: Learn More About Blogger.
I know how to enter meta info on each blog post under the Search Description field - but do I have to put all permutations of a subject in the Search Description?Here, we see the possibility of unintended "keyword stuffing", and degraded search engine reputation.
We must be careful to not misuse the meta search description feature - and avoid keyword stuffing.
Well written meta descriptions can help search reputation.
A well written meta description can be part of a well designed blog and of well written posts. It can help search engines index a blog, or a post, properly - and in a SERP listing, can attract readers.
Contrarily, a collection of meta keywords can look like keyword stuffing. The latter can cause degraded search engine reputation.
Search engines are long past benefiting from meta keywords.
Search engines have long been made more introspective, than for a blog to benefit from meta keywords. Search engines now extract keywords from indexed content, automatically.
While it is possible to design blog or website pages to use keywords, keywords now are extracted from visible content. Google is quite blunt about meta keywords.
Google doesn't use the "keywords" meta tag in our web search ranking.
Write good posts, to get good SERP positions.
If you want good SERP positioning, write good posts, using informative, interesting, and unique content. That's the best advice, for Blogger blogs.
Some #Blogger blog owners still try to use meta keyword tags, to improve search engine reputation. They don't realise that search engines now develop their own keyword lists, from visible content.
Good search list positions come from good content, to be read by people - not from jumbles of words, randomly strung together.
