  Mateusz Mucha: We're about to launch a website with multiple (hundreds) of tools (sorry for the nth intro, I feel I should include it every time). The core element of our SEO strategy is the fact that all of these tools can be embedded on other websites.
  
  I know it's OK now to not nofollow the link to us, but I was advised to include our brand name instead of the tools' names as the anchor text. And that was my goal, but I'm feeling I might be missing out on the value of an exact match text.
  
  I've done some research and I saw a few highly successful examples of doing something similar. For example, if you Google "pogoda" (weather) or "pogoda {name_of_any_city_in_poland}" (example: "pogoda krakow"), you'll get a certain website as #1. They have really nice weather widgets with "pogoda {city_name}" as an anchor text.
  
  My niche is calculators, so I'd like to do something like "[link]kinetic energy calculator[/link] made with ♥ by [link]{brand name}[/link]. What do you think?

  Edwin Jonk: I would stick to one link and one line in the by-line. So you don't scare away the webmasters that use them.

  Mateusz Mucha: +Edwin Jonk: I realized I haven't asked the question properly... should I be worried about Google disliking these keyword-based links?

  Webhosting 4 Business: Not as long as they are relevant and you haven't done it 1000 times.

  Mateusz Mucha: +Webhosting 4 Business: these are embeddable widgets - the whole idea is that (eventually) 1000s of websites use them.

  Webhosting 4 Business: +Mateusz Mucha ;I meant don't over use each term, it should never exceed 2.5 % of your total word count and don't overstuff the URL and you will be fine.
