Does Google search show the title formed in meta-title or h1?

Question

Search Engine Optimization

1. When Google lists a product, does it take data from the title or H1 tag for the title?
2. If the title and h1 tags are the same, will this enhance the effect for Google or not?
3. What is the maximum number of keywords that can be used in a title, title tag, or h1 tag?
4. The hum will not impose sanctions on us for such a headline: Winter tires (rubber, slope) R14 175/70 BAR GUM EXTRA GRIP 84 Q, welding from Poland ......... .. here are 5 keywords?
5. And it’s worth using someone in the headings, for example, in the question above before the word welding, or is it better to write without, do you mean for Google?
6. is it worth creating meta-description and meta-keywords at all? If so, what is the best number of characters for a meta-description and how many keys should I put in meta-keywords?
7. Can Google itself generate a short description for displaying to the user from the text of the description of the product or article?
8. If I have a Ukrainian-language article .., but I see that most of the keys and Google Edword grew up, then can I write like this: Winter tires (winter tires) R14 175/70 BAR GUM EXTRA GRIP 84 Q, welding with poland ... .. so that ruskomovni requests catch or google itself translates and gives out my article .. on request winter tires R14 175/70?
9. And in general, is it worth it if I have Ukrainian .. and Russian. Do you have site localization?
10. Will the query work if the words are rearranged or if the query matches one word from the key, for example, a person entered: buy tires in Lviv, and my heading starts with “Winter tires .......”?
11. The site sells only tires, just different brands, models, sizes. So you need to make a site map and enter there a list of links to the card page of each product, as well as generated links by selection through the filter?
12. And the site itself is on Opencar, is there a system that automatically generates a sitemap?
13. And I noticed that the site often changes something in the name of the product, and, accordingly, a new link to the card, since it is formed from the name ... .. Maybe it's better in this case to form links to the product card by ID?

Answer 1

1. Most often title.
2. Better to cover semantics and write h1 with differences.
3. Depends on semantics. There are no restrictions.
4. No.
5. Reframe the question.
6. Description yes, keywords no. The description has ~160 characters.
7. Yes.
8. Google won't translate.
9. Russian-language requests - for the Russian-language version, Ukrainian for Ukrainian. No need to reinvent the wheel.
10. Depends on what character operators are used in the advertising company. If you have "winter tires..." in quotation marks, it won't work.
11. It’s worth doing a sitemap, and you need to enter there what you would like to be indexed by Google.
12. Xs.
13. The key in the url will be a plus for you in ranking. It is better not to change the names, or make redirects from the old names.
