What are the tools in services marketing for more penetration into market?

you can penetrate any market if you have a superb customer service and highly demanded products, However, the chance to capitalize on relationships and their connections Integrating and interlinking creates opportunity to increase your customer-base services and marketing your image towards success.

i would add to Ahmed's points the following:
1- try to create a more client-centric service "packaging" approach by shifting the focus to the needs, pains, and benefits of your client rather than your product/service features.

2- you may also try to look for good partners who have complementary/added value services and offer with them that integrated services package; this will help you to stand out from the crowd.

3- try to increase your public exposure, not by the number of show-ups but by making actions/networking for impact.

4- always focus on your client and where you want to have your "positioning" in the market.

5- remember that it's always about making the balance of benefits and interest for all the strategy stakeholders.
those are some hints and there is even more !!
