I like all the reference samples, but MAXLink stands out the most. Open to all designs. I would like to separate the colors on SEM and LINQ in the logo. If you visit Ahrefs.com I also like their logo. I am looking for a unique logo that we can use for years to come and these colors will be the baseline for the website.

Possibly would like to have a link icon in the logo. I like the colors of MaxLink the most. Trying to create a new brand and basing it off the logo design and colors, so good luck and hope you design the next Facebook logo here.

Just an idea, but maybe you could do something with the q on the end of SemLinq. Possibly make it a link. Although I am not a designer so leaving discretion up to all you great designers.
