Keyword research tells you what topics people care about and, assuming you use the right SEO tool, how popular those topics actually are among your audience. The operative term here is topics -- by researching keywords that are getting a high volume of searches per month, you can identify and sort your content into topics that you want to create content on. Then, you can use these topics to dictate which keywords you look for and target.
QUOTE: “Many websites are eager to tell users how great they are. Some webmasters have read these rating guidelines and write “reviews” on various review websites. But for Page Quality rating, you must also look for outside, independent reputation information about the website. When the website says one thing about itself, but reputable external sources disagree with what the website says, trust the external sources. ” Google Search Quality Evaluator Guidelines 2019
Hi Kai! Using synonyms now and then is a great idea. It definitely makes your copy more natural and pleasant to read. And Google will comprehend that you’re talking about the same topic. You might want to use the keyword you’d like to rank for a bit more often than just once or twice, but don’t fret to use synonyms now and then. We’re not able to detect them with our tool yet, though.
Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
Ask for a technical and search audit for your site to learn what they think needs to be done, why, and what the expected outcome should be. You'll probably have to pay for this. You will probably have to give them read-only access to your site on Search Console. (At this stage, don't grant them write access.) Your prospective SEO should be able to give you realistic estimates of improvement, and an estimate of the work involved. If they guarantee you that their changes will give you first place in search results, find someone else.
