: SEO: adding your company signature with link to all websites you make? I saw many webdesigner companies adding a small signature on each website they make. Signature could be masked by words

I don't think there will be any penalties for having such links. A lot of popular web services, applications, etc. have button links or badges that are used on tens or hundreds of thousands of unrelated sites—e.g. Media Temple, Facebook, Twitter, WordPress, CakePHP, ExpressionEngine, MySQL, PHP, VeriSign, W3C, PayPal, Creative Commons, etc.

For most designers/developers, you won't be developing enough sites to even come close to the amount of badge links that the above mentioned services have. So if jQuery and Drupal don't have any problems with their thousands of backlinks, then the average web developer certainly has nothing to worry about.

Something to consider is whether or not the linking sites are hosted on the same server and have the same IP address. If they are provided/hosted by the same company then this is quite possible. If the websites in question that link back to the website provider have thousands of pages (i.e. an ecommerce website) and a link is present on every page then there is a possibility these links combined will devalue any potential benefit.

Note: I'm unsure if this would result in a penalty of some kind for too many links from the same IP address, I've never seen this personally, however perhaps other community members have? There are a wide range of theories on this confirming/denying penalties, however based on the known facts about linking it feels sensible not to have thousands of home grown links from the same source.

As a rule of thumb keep it to the homepage only and keep it small and near the bottom.

As always, it's good only so far as the link is valuable. If the page the link is on is unrelated to your website, and in these cases they almost always are, it won't have much value to you. You will get some PR (but not much if they don't get much PR themselves) and some value from the link, but it really won't be anything significant. I would not expect it to push your site up significantly in the SERPs for web design and development related queries.

(I generally don't like this as it makes the client's website look less professional. Always get permission to do this from the site owner and let them know the SEO ramifications to them.)
